I can vouch for them as a seller in the same way, I've also gotten reasonable 
prices from them when making offers that account for shipping, and the seller 
actually knows how to pack stuff. Same with eBay seller jonnyadler, though

[Chris Hanson via cctalk]

I just looked at the prices on eBay—yikes! All of my HP hardware from that era 
was pretty inexpensive a few years back.

What are people using the B180L for that’s driven the prices so high? I assume 
it’s another “there’s a piece of equipment that was built around this specific 
platform 20+ years ago, and we’re still running it so we need spares” 
situation, just like the equipment that was built around the VAXstation 4000 
Model 90 which keeps the price on that insane.

Is there a specific need you’re trying to fill? I wound up with an additional 
B- or C-series workstation as part of a deal, I can check what model it is 
(it’s in storage right now) and we can talk off-list about maybe getting it to 
a good home. (I’m in the SF Bay Area if that helps, no idea where you are.)

It’s NetBSD, of course it can run!

The real question is: Does it currently run? If the answer is “No,” it’s just a 
port away as long as sufficient information about the CPU and platform is 
available.

The modularity in NetBSD that enables this is its greatest strength. It enables 
things like the newly brought up “virt68k” platform which is basically NetBSD 
for a QEMU-hosted 68K emulator with VirtIO, which can be useful for things like 
kernel testing and pkgsrc builds.

I have a variety of VME hardware that I use some of the time, and on the 
ClassicCmp Discord we even have a #vme channel.

I've mostly been using a Motorola MVME167 (with some additional VMEbus memory 
cards) netbooted to NetBSD off and on, though I also have 147 and 177 cards 
(68030 and 68060) that I'll use. I also have a couple of MVME197 88000-based 
cards that I've used to port OpenBSD-mvme88k forward by one point release from 
when they dropped support. (I wish NetBSD had mvme88k…) And I have a couple 
other 68K VMEbus cards like a Xycom XVME-600 and XVME-630; the 600 is cute and 
runs Mach2 FORTH from ROM, while the 630 is a more or less generic 68EC030.

I have a variety of peripheral cards that I've been trying to do various things 
with, including a slick RasterGraf RG-750 graphics & human interface card (it's 
34010-based and has AT keyboard and serial mouse ports), a couple NI GPIB 
cards, and a bunch of earlier cards like Motorola HD/floppy, Ethernet, SCSI, 
and intelligent serial cards, and so on.

I also have a few older Motorola 68010 and 68020 boards; I want to bring up 
MINIX 1.5.10.7 at some point on my MVME050+MVME121 and see if I can't get it to 
leverage the MMU. And I have a VME/10 workstation that needs to be put back 
together that I'd like to run Motorola SVR2 on.

Finally, I have a bit of more exotic gear. I have a couple of the INMOS 
Transputer VME cards (as well as the non-VME equivalents for my ITEMs) and I 
have a few Mercury Computer Systems i860 cards for which I really, really, 
*really* want to find documentation someday. It'd be a lot fun to have a bunch 
of i860s rendering a scene or something that I can then output via the RG-750, 
controlled by an 88K...

Oh yeah, and I have a few Suns and a Symbolics that use 9U VME, as well as a 
couple ISI systems that use 6U VME[1].

[1] ISI used their own QBus-style ejectors on the card top instead of the

VMEbus was widely used as a successor to MultiBus in the workstation market, a 
lot of vendors that started with MultiBus (Sun/SGI for example) switched to VME 
because they were using 68K anyway and it a supported full 32-bit address and 
data space, where MultiBus was mostly designed for 8080/8085/8086 (and even 
8086 required some extension to support 16-bit data bus width and 20-bit 
address space).

The biggest uses of VMEbus though were in laboratory automation, process 
control, and robotics, where it was in competition with both MultiBus and 
DIO[1] (the bus on the HP 9000-200 and 9000-300 series, which were originally 
designed as successors to the HP 1000/21MX/2100 series). That's why you'll see 
a lot of analog and digital I/O hardware, computer vision systems, motor 
controllers, and so on in the VMEbus 3U and 6U form factors. This is also what 
got VMEbus used in a lot of American defense applications.

[Chris Hanson via cctalk]

Apple didn't "steal" anything because Xerox received a tranche of pre-IPO Apple 
shares in exchange for allowing SJ and his folks to visit PARC for a bunch of 
demos and do whatever they wanted with what they saw.

Nowadays you can also try out systems like Smalltalk-78, Xerox ViewPoint, etc. 
as well as the original Lisa and Macintosh systems in emulation -- and read 
papers like "Inventing the Lisa Human Interface," published in ACM Interactions 
27 years ago -- to see just how different what SJ and his people saw at Xerox 
was from what Apple shipped in the Lisa and Macintosh 4-5 years after the visit.

- The top-of-screen menu bar was an Apple invention.
- Atkinson's "region" data structure to allow windows to update when partially 
obscured was an Apple invention.
- Open/Save file dialogs were an Apple invention for Macintosh, because with 
128KB of RAM it couldn't run both Finder and an application and thus couldn't 
use Lisa's "stationery pad" concept.

I can't believe people still don't have a solid grasp of these things after 40 
years of both journalism and academia covering them in rather exhaustive detail.

[cctalk] Re: Computhink Eagle 32 - software, docs, info?

[Chris Hanson via cctalk]

I picked up this system from its previous caretaker yesterday, to hold onto for 
a friend. I’ve also inventoried the major functional ICs and archived the 
“IPL-M” ROMs.

Here’s what’s in the Eagle-32:

- Main Logic Board
  - 8MHz 68000 CPU
  - 2x D8255 programmable peripheral interface
- left 8255 is clearly for parallel and user port
- right 8255 I strongly suspect is for hard disk, possibly ANSI or SASI
  - D8253C programmable interval timer
  - 2x 2651N programmable communications interface for serial ports
  - 2x 2716 for IPL-M 0/1 ROMs
- Disk Controller Board
  - FD1701B-02 floppy disk controller
- No video board, whether text or graphics

Since there’s no video board in the system, and a couple of cables internally 
that aren’t attached to anything, I expect it was removed by a previous 
caretaker. This is sad because without one it’s unlikely to come up, not that 
anyone has found any software for it. On the other hand, there are zero PALs, 
so both full reverse engineering and maintenance should be straightforward.

I threw the 4KB of boot ROM in Ghidra and confirmed a couple things:

- At boot, ROM is mapped to 0, and then remapped either by a write to the 
location or by a cycle counter: The initial stack pointer at 0x0 is 0x0001fffe 
and the initial program counter at 0x4 is 0x00ffc026, indicating the ROM is 
normally located at 0x00ffc000.
- The ROM freely interchanges addresses in the 0x00ffc000..0x00ff range and 
addresses in the 0xc000..0x range, which is annoying to deal with 
in Ghidra.
- I/O devices appear to be in the 0x00ff8000..0x00ffbfff range, all of the 
devices accessed via the bootstrap seem to be barely above 0x00ff8000.
- Only NMI, bus error, interrupt 2, and interrupt 5 are set up by the bootstrap.
- The bootstrap is very bare-bones but still has a bunch of indirection in it; 
it’s obviously written in assembly, but it does seem to have parameterization 
so it may support both console and serial I/O.

I suspect that I can figure out from the pattern of I/O accesses which devices 
are at which address in the memory map, at least if I bring up an emulation in 
MAME. That should at least allow writing new code for it, and _maybe_ even 
figuring out which CRT controller the video hardware uses and where in the 
memory map it is. (I suspect the 6845 and/or 6847 just from the time period, 
but who knows? Gotta see what it actually do when trying to show the “IPL IN 
PROGRESS” string contained in the ROM, or one of the couple error strings…)

Does anyone have a list of replacement capacitors to use for NCD X terminals,

I just got my NCD 17c up and running—I showed a pic or two on 
discord://classiccmp/#terminals a couple days ago—and now while I hear the HV 
power up the low voltage power seems kaput and the system never comes on. And 
my NCD 19 won't power up either.

I can certainly take them apart and make lists, and I will if need be, but I 
was hoping maybe someone had already done so so I could get an order in ASAP. 
The power supply for these things is in the display portion, which makes me a 
bit nervous just generally… :)

That’s the difference between the PT68K1 and PT68K1A. The system featured in

PT68K2, which is the version with PC-XT slots, keyboard support, and PCB

I think you have it backwards: The way I read Rich's message, former LCM+L

Microsoft, Google, Apple, Facebook etc. were willing to pay all of the

regular wages through the pandemic even when nobody was allowed in the offices.

LCM+L, being owned by a billionaire's foundation, could have chosen to do that

They and the entire engineering staff should have been kept on until the museum 
could reopen, doing whatever work they could remotely, and should still be 
working there now.

That they weren't shows how little the foundation cares for the things Paul 
Allen cared about.

While I prefer the way LCM+L made working systems available to the public over 
the CHM's mostly-static "behind a velvet rope" approach, CHM has turned out to 
be the better institution since they at least kept people on.

[cctalk] Bubbl-Tec bubble memory (QBus)

I just acquired the several Bubbl-Tec bubble memory boards for QBus, and was 
wondering if anyone had manuals or more information than the couple of web

MBC-11A bubble memory controller
MBB-11A bubble memory board for use with MBC-11A
QBI-11C bubble memory board
QSB-11A bubble memory board with RX01/02 emulation

It looks like I can just drop the QSB-11A into a system and it should work as 
if it's an RX01 attached to a controller, but the other boards appear to need 
cabling and possibly jumpers to configure them for use, and maybe custom

Later Data General (D214/AViiON) keyboards?

[Chris Hanson via cctalk]

No, I'm not looking for old Dasher keyboards because "omg Severance."

I have a couple of Data General terminals (D214) and a couple of Data General 
UNIX workstations (AViiON, using m88k CPU) and only one keyboard. The one that 
uses an 8-pin DIN connector similar to the 5-pin IBM PC XT keyboard 
connector—and it speaks the same protocol over the same lines, but also has a 
couple extra features enabled by those extra 3 pins. (I believe the part number 
of the DG keyboard is 6348, but I'm not positive and can't find my reference at 
the moment.)

Does anyone have any more of the keyboards for D214 terminals or AViiON 
workstations that need a good home, a home which reunites them with appropriate 
hardware? I gather I can use XT-compatible keyboards with the AViiON systems at 
least, because of the compatibility I noted above, but I don't know about my 
terminals.

If this is still available, I would pay for someone to pick this up, pack it, 
and ship it to California. (I'd also send John money for it too, IMO it's only

If this is still available, I would **desperately** like to acquire all of the 
above. Again, I'm willing to pay someone (and send money to John!) to pick this 
up, pack it, and send it to me in California.

I have MacMinix 1.5, but a couple of my disks are bad, and I'd really like to 
have the other Minix bits too. Literally simultaneously with John's sending of 
this email, I was running the Mac IIfx in my office at Apple, and rebuilding 
all of MacMinix 1.5.10.7 at -O2... Seriously! (Part of a personal project to 
port Minix 1.5.10.7 to a 68010 VME board set.)

My first Open Source contribution was to MacMinix. I created a patch that 
flushed the instruction and data cache on the 68040 when necessary (probably 
too often, in fact) so it would run nice and fast on the Centris 610 that I 
upgraded to from a Mac IIci in late 1993.

In any case, if I don't get these myself, I hope they went to good homes, and 
I'd absolutely love it if whoever got them could make and share disk images of 
the MacMinix disks since right now the only publicly-surviving artifact is the

Even when viewing files locally, linearization is important for not having to

PDF requires page independence so linearization isn't what puts the information

the PDF is in presentation order. You can jump around and scroll in a PDF by 
doing byte-range fetches even without linearization, but you may have to do

WTB: HP 9000-340 memory (HP 98268A), AUI (HP 98235A), SCSI (HP 98658A)

[Chris Hanson via cctalk]

I've acquired an HP 9000-340C+ and I'd like to kit it out with the maximum RAM, 
SCSI, and AUI rather than thin Ethernet. Desired:

- RAM boards: HP 98268A RAM board (three of them to get to 16MB, I'd probably 
buy extra just to be safe)
- AUI LAN board: 98571-66534, aka HP 98235A AUI LAN Upgrade
- SCSI board: HP 98658A SCSI Interface Card

Anyone have any of this stuff that they might be interested in parting with?

I'm also always on the lookout for an HP 98556A 2D/integer graphics accelerator 
in case anyone happens to have one that needs a home. That's the integer 
accelerator with a 68020 and some RAM, which piggybacks atop the 98550A 
(1280x1024 8-bit color card) via its extra Eurocard connector.

I think Al has contributed enormously to the archival and preservation of our

better way to do something.

Also, I'm 100% with Al about not siloing projects _on social media sites like 
Facebook_. They're terrible for technical projects because they're specifically 
designed to surface "engaging" social information and push further engagement, 
rather than to actually preserve chronology, or to make it easy to refer back

the whim of The Algorithm.

Mailing lists are by far the best choice when it comes to collaboration on 
technical projects, with tools from project hosting sites like SourceForge, 
Bitbucket, GitLab, and Github a close second.

I was able to build its three component libraries just fine with CodeWarrior 7

It did, but it was also in the process of switching to libssh2, so Brendan 
switched that from OpenSSL to mbedTLS too:

Great work, Cameron!

Another option for these systems is mbedTLS, originally by ARM. It only 
requires C89, it can serve as a replacement for SSL libraries that follow the 
standard API signatures, it is also quite easy to build (a little more 
complicated than Crypto Ancienne, though not by much--you just need to examine 
its GNUmakefile to derive a build system for whatever OS you're targeting), and 
it's fairly complete.

One advantage of mbedTLS is that it works with libcurl, libssh2, etc. already 
so if you need to build more such things you have a good basis to start from.

At some point MacSSH may use it. Or maybe the current maintainer will try 
cryanc. :)

Re: Anyone want to part with a DEC MXV11-B (M7195) and/or M8012 (BDV11)?

[Chris Hanson via cctalk]

Thanks to everyone who replied, on- and off-list! There’s an MXV11-B (M7195) on 
its way to me. :)

Since people were asking about my setup, here’s what I have:

- MDB BA11-clone enclosure, PSU, and 8-slot 22-bit backplane
- DEC KDF11-A (M8186) rev C processor with FPP added
- DEC DLV11-J (M8043) SLU
- Motorola M1132 128KW RAM

And some stuff that’s untested but I’m eager to try:

- (soon) Emulex UC07 SCSI controller
- (soon) DEC MXV11-B (M7195) system controller
- DEC MSV11-LF (M8059) 64KW RAM
- DEC DEQNA (M7054) Ethernet controller
- DEC RLV12 (M8061) RL01/02 disk controller
- MDB MLSI-SCM11 system controller

For the latter two, I need to figure out whether my backplane supports ABCD use 
in the first couple of slots, or if it’s purely an ABAB model. (The KDF11-A, 
RLV12, and MLSI-SCM11 came in the backplane, but I’m hesitant to interpret that 
as ‘these were configured together in this pattern” rather than “these happened 
to fit in here for storage.”)

I’m actually still looking for docs on the MSLI-SCM11, since it looks extremely 
configurable and I have no idea how to use it or what it’ll provide…

As for what I’m going to do with it, I’m thinking XINU. Comer’s book is one of 
the two books via which I learned C (Tannenbaum’s was the other) so I think 
that’d be a fun system to have up and running, especially since it has IP

Anyone want to part with a DEC MXV11-B (M7195) and/or M8012 (BDV11)?

My little LSI-11 system doesn't have a usable Line-Time Clock because it lacks 
the register, which it expects to be in either an MXV11-B (M7195) or a BDV11 
(M8012). My power supply theoretically supplies the LTC but I haven't confirmed 
that, so my preference would be an M7195 if possible.

Does anyone have one they'd be interested in parting with? I'm fine with 
shipping internationally and with paying a reasonable price, and I promise to 
take good care of it and pass it on to another good home if I should ever part 
with it. (Friends don't let friends recycle rare electronics.)

Alternately, is there a "modern" Q-bus board that provides things like LTC 
(both the clock and the register), SLU, memory, etc.?

Yes, the Andrew environment implemented proper layering, so ATK was made to 
work atop X and the applications (messages, ez, console, typescript, etc.) came 
along.

At Carnegie Mellon in the early 1990s, you could (with only a little work, to 
use a console rather than graphical login) use either X or wm on some of the 
campus workstations. On a DECstation 3100 running Ultrix, if you weren’t going 
to run any X applications wm was *much* more responsive. I wasn’t around when 
the clusters had Sun-3 or IBM RT hardware but I can imagine the differences 
there were even more pronounced. (With wm, a DECstation felt as much faster 
than a Mac II as it actually was…)

Applications built against ATK could run atop either wm or X; I don’t know if 
there were distinct builds of ATK or if the conditional logic was in the 
framework itself, but the applications themselves worked just fine with either 
since Andrew implemented a shared library mechanism. (Yes, even on Ultrix.)

The publicly-released Andrew distributions don’t include the wm code, only the 
X version. I don’t know if they’ll actually build against the wm headers and 
libraries if they’re present, or if by the time CMU was releasing them publicly 
they had stripped that code out entirely.

CMU Andrew system (and wm) preservation

[Chris Hanson via cctalk]

Back before X11 took off, IBM funded CMU's development of Andrew, which had its 
own complete window system represented by its "wm" window manager. One of the 
many things that led to X's prevalence was that to get ahold of Andrew and wm, 
you had to license it from IBM, whereas X was licensed freely by MIT and 
available via FTP, tape, etc.

When I was at CMU in the early through mid 1990s, the CMU Computer Club 
continued to maintain a fork of "wm" called "wmc" that was available to club 
members, including source code. While I'm pretty sure I have an archive of this 
code on a Zip disk somewhere, I thought I'd put out the call to the community 
to see if anyone else had preserved early Andrew bits since they're both 
historically important and architecturally interesting.

What's architecturally interesting about them? Among other things, CMU created 
their own shared library mechanism for Andrew, and their own object oriented 
dialect of C (implemented via a separate preprocessor) that was surprisingly 
similar to Objective-C. The entire Andrew system was also component-oriented, 
such that it supported embedding components for handling different media types 
within each other, while keeping the embedded ones editable -- most of what 
developers got later with OLE and OpenDoc.

So it'd be great if this stuff was archived in such a way that it could be used 
with contemporary systems, whether emulated or real hardware. Has anyone done 
any of this yet?

Link-time optimization has been a thing for a few decades, independent of 
whether GCC & GNU ld supported it. And very few compilers actually do anything 
any differently when all of the sources are passed in one go; to follow the 
spec, the compiler must consider each compilation unit independently, which 
it'll typically do by spawning one compilation process per compilation unit.

This also means the build system can't manage the build's parallelism, which is 
something you really want on a large project.

Build times really do still matter. On my modern hardware SIMH still takes long 
enough to build that it's a hassle.

In my experience the more complex the Makefile, the less likely it is to be 
correct, and there's an enormous amount of unnecessary complexity in SIMH's 
Makefile—especially since it doesn't just build the simulators but also runs 
their tests without being instructed to. SIMH's Makefile results in a lot of 
unnecessary rebuilding and waiting.

You don't even need careful dependency tracking to improve this, just regular 
make behavior. What's more, the way the Makefile is currently constructed 
interferes with your use of `make -j4` by producing unnecessary output.

In short, cleaning up the build to work like any other make-based project would 
result in faster builds and make SIMH easier to work on for people interested 
in doing so.

Did you miss the part where I said it would make it much easier to experiment

SIMH improves quickly enough that you won't want to do a 20 minute build every 
3-12 months, but instead perform new builds with some regularity.

Between that and ease of experimenting (or the lack thereof) a bad build system 
can really hold back a project.

Oh yeah, NetBSD 9.0-stable 64-bit also only takes a few seconds to boot on a

Re: SIMH on low overhead platform

[Chris Hanson via cctalk]

One thing that would make it much easier to experiment with SIMH in scenarios 
like this is if its build system wasn't horribly redundant. It genuinely looks 
like someone looked at make and said "How can I turn this into a procedural 
scripting system?" and then wrote the SIMH makefile in that style.

It should only take a couple seconds to build SIMH but instead it takes a 
couple minutes, rebuilds a ton of things redundantly, and runs all sorts of 
testing as a side-effect (instead of having that under a separate target).

At one point I worked out that most of the preprocessor macros fall into just a 
couple of buckets so building SIMH could be separated into building just a 
couple of libsimh libraries from the same sources (one for 32-bit simulated 
pointers, one for 64-bit simulated pointers) and then most of the rest of the 
targets could *just* be the target-specific sources plus the right libsimh.

Unfortunately (1) I can't contribute back that change if I make it without 
jumping through a lot of bureaucratic hoops (employment agreement) and (2) the 
current maintainer appears to not want to hear any criticism whatsoever of 
SIMH's build system.

The originator of the Reddit thread works on this simulator and is the point of

They're really interested in moving off the Sun 3/e rather than continuing to

fuses, especially on the Ethernet/SCSI cards, since the originator claims

Just so you know, the file named MVME332XT is actually MVME332XTFW and the one

macOS switched to launchd from inetd a very long time ago. If you're going to 
use macOS as a UUCP node you'll want to enable the com.apple.uucp service, 
which will ensure uucico is run for you by the system.

That's a macOS difference, not a BSD one. I don't *think* you need to re-add 
any setuid or setgid bits, but I could be mistaken. It's been a very long time 
since I've actually used UUCP. If they do need to be made setuid or setgid, 
that sounds like a bug.

In macOS 10.14-10.15 these files are indeed covered by system integrity 
protection, I think that's probably a bug since they need to be edited by a 
sysadmin to use UUCP.

It looks like what I’m looking for from CSPI (aka CSP, Inc.) is the “SuperKit”

There are mentions of it in the Wayback Machine for http://www.cspi.com/ and

Pine/Alpine should show the text portion of any multipart messages perfectly 
reasonably, and not even attempt to download non-text MIME content from your 
IMAP server. Crispin designed the application and the protocol that way 
intentionally; his approach was always that you should be able to run your MUA

At the fruit company there are a few such employee-curated displays but so far 
as I know we’ve never had such problems. Of course, there’s also the fact that 
only employees have access. (And even before the phone, when some guests were 
allowed in some areas, they had to be personally escorted at all times.)

Back during the mid-1990s there was a small “museum” display by the cafeteria 
of some inactive hardware under glass, and there was also a big lab of our 
products from every era off the engineering support library upstairs in the 
same building. That lab was more like LCM in that you could just go to it and 
work with anything; it was maintained by the engineering support library and 
only accessible to employees, so that’s probably why it never had serious 
problems with people breaking or stealing things.

LCM+L is owned and operated by Paul Allen’s $20 billion estate. They are not 
hurting for cash, though I’m certain some bean-counter at Vulcan sees 
continuing its operations during the pandemic as a drain on resources. 
Management by the numbers.

The actual Living Computer Museum + Labs was *great* to visit, and from the 
outside worked exactly like you would expect a museum about computing history 
to work: A visitor to the museum could actually *interact* with most of the 
systems they had, they weren’t just displaying static artifacts behind a velvet 
rope or pane of glass with a placard describing them. The stuff you couldn’t 
interact with directly you could still interact with through terminals and even 
the Internet.

This is one of the things that disappointed me most about the Computer History 
Museum in Mountain View, CA. Sure you can’t let the public interact with 
*everything*, but since so much of computing since its inception has been about 
interaction with active systems, just displaying them is leaving out a large 
amount of what really makes them interesting. The CHM does a lot of great 
preservation, archival, and curatorial work, but this really feels like a 
glaring omission.

It might be a battle, possibly even a major one, but it would be fundamentally

That may, of course, be why they told Alan they don’t take loans; they may want

Re: Living Computer Museum

[Chris Hanson via cctalk]

The big problem with this situation is that it’s simply unnecessary: Living 
Computer Museum + Labs is not independent of Vulcan, and Vulcan can *easily* 
afford to keep the people who work there on payroll and working from home 
indefinitely.

This is happening entirely because the people holding the pursestrings have no 
idea how to run a museum, or even what a museum *does*. It’s pretty clear that 
they think they can just pack things away for a while, then hire a few people 
to take tickets and put out exhbits when they decide to reopen, without any 
consideration to the kind of historical preservation work the museum is in the 
process of doing or even what might need to be done to prepare exhibits for 
public access, what it means to be ready to obtain, receive, and preserve 
newly-uncovered historical artifacts, and so on.

https://twitter.com/eschaton/status/1265751114953011200

A group of people who actually understand (like Woz and Gates et al) should 
step in, take it off Vulcan’s hands, and endow it as an independent entity. And 
people should stop donating their collections to museums and lend them instead.

These days, the RAM on a lot of development boards is DDR or something else

I think it depends on whether you want to expose *Ethernet* to the device 
you’re implementing, or just to provide access to it *over* Ethernet. Exposing 
serial and other channels via SPI or I2C is certainly straightforward.

Of course, there are also IP blocks for I2C and SPI, some of which may again 
map to dedicated hardware on the FPGA, providing more room for your logic.

So yes, context matters, but you need to look at both what you want to 
accomplish *and* what the tooling and FPGA you’re using can provide.

Why do more integration work than you have to when you can focus on the 
interesting stuff?

I’d strongly suggest that the situation with FPGAs & HDLs requires a bit more 
nuance than that. You *should* probably avoid or carefully isolate vendor 
*language extensions*. However, you *should not* avoid vendor *IP blocks*.

As an example, let’s say you have a design that needs a RAM controller. Do you:

(1) Write your own DDR controller as part of your design; or,

(2) Interface your design to your FPGA vendor’s DDR controller IP block?

In general you *should* do the latter—as long as you can do so via a sane 
abstraction—rather than the former, unless you have an extremely compelling 
case for doing the former.

And “portability” isn’t actually that compelling of a case: Virtually every set 
of tools and chips you might want to work with will have a similar variety of 
IP blocks available, many implemented via dedicated on-device logic (rather 
than consuming general-purpose logic cells), so as long as you can isolate 
their use you can still keep your overall design portable.

This is particularly important for things that have strict timing requirements 
and that might otherwise soak up a lot of your device’s bandwidth, e.g. HDMI 
input/output, RAM control, Ethernet, and so on.

Nope, Mac OS X 10.0 was significantly upgraded and based on Mach 4 and BSD 4.4 
content (via FreeBSD among other sources). It was NeXT that never got beyond 
Mach 2.5 and BSD 4.2. (I know, distinction without a difference, but this is an 
issue of historicity.)

I think only some of the changes from Mach 2.5→3→4 made it into Mac OS X Server 
1.0 (aka Rhapsody) so maybe that’s what you’re remembering.

It was the original Linux port for NuBus PowerPC Macs at least. It was never 
really intended to “get very far” in the first place, it was more of an 
experimental system that a few people at Apple threw together and managed to 
allow the release of to the public.

MkLinux was interesting for two reasons: It documented the NuBus PowerMac 
hardware such that others could port their OSes to it, and it enabled some 
direct performance comparisons of things like running the kernel in a Mach task 
versus running it colocated with the microkernel (and thus turning all of its 
IPCs into function calls). Turns out running the kernel as an independent Mach 
task cost 10-15% overhead, which was significant on a system with a clock under 
100MHz. Keep in mind too that this was in the early Linux 2.x days where Linux 
“threads” were implemented via fork()…

I don’t recall if anyone ever did any “multi-server” experiments with it like 
were done at CMU, where the monolithic kernel were broken up into multiple 
cooperating tasks by responsibility. It would have been interesting to see 
whether the overhead stayed relatively constant, grew, or shrank, and how 
division of responsibility affected that.

Not quite! Sun was a participant in creating the OpenStep standard (the NS 
class prefix stands for “NeXT/Sun”) and *created their own implementation* of 
OpenStep for Solaris. (Just as GNUstep is an independent implementation of the 
OpenStep spec under the FSF umbrella, and OPENSTEP/Mach and OPENSTEP/Enterprise 
were NeXT’s implementations.)

OpenStep Solaris was released, both the user and developer environment, and you 
should be able to find them today and install them on Solaris 2.5 or later. I 
think OpenStep will run on everything through Solaris 7 or Solaris 8, but at 
some point it stopped working because it required Display PostScript in the 
window server.

Indeed, that was post-OpenStep; they weren’t buying companies like Lighthouse 
to get a suite of applications for OpenStep Solaris, they were buying them to 
port their stuff to Java (since Java was based rather heavily on Objective-C, 
and some aspects of the Java frameworks’ designs on OpenStep).

Pink was the C++ operating system project at Apple that became Taligent. I know 
a couple of people who did a developer kitchen for Pink pre-Taligent, and I 
also know a number of folks who worked on the Taligent system and tools—and 
have personally seen a demo of the Taligent Application Environment running on 
AIX.

I’ve even seen a CD set for Taligent Application Environment (TalAE) 1.0 on 
AIX, and I have a beta developer and user documentation set. Unfortunately my 
understanding is that the CD sets given to employees to commemorate shipping 
TalAE were all *blank*—the rumor I’ve heard is that IBM considered it too 
valuable to give them the actual software that they had worked for years on. 
(Maybe there were tax implications because of what IBM valued the license at, 
and the fact that it would have to be considered compensation?)

Taligent itself was only one component of IBM’s Workplace/OS strategy, which 
was a plan to rebase everything atop Mach so you could run AIX and OS/2 and 
Taligent all at once on the same hardware without quite using virtual machines 
for it all. The idea is that Apple would do pretty much the same with Copland 
and Taligent atop NuKernel rather than Mach.

It would be really great to actually get the shipping Taligent environment and 
tools archived somewhere. While only bits and pieces of it are still in use—for 
example, ICU—a lot of important and influential work was done as part of the 
project. For example, the design of most of the unit testing frameworks today 
actually comes from *Taligent*, since Kent Beck wrote SUnit to re-create it in 
Smalltalk, and JUnit and OCUnit were based on SUnit’s design and everything 
else derived from JUnit…

Does anyone have a spare internal or external SCSI cable for the IBM RS/6000 
Model 320 with the IBM MCA SCSI-1 card (3-1)? For those who don’t

than an IDC connector to connect to its internal two-drop cable, and its 
external connector is a **sixty-pin** higher-density Centronics connector.

I can make an IDC cable adapter pretty easily but if anyone knows where to 
acquire working original cables, that’d be preferable to my relative lack of 
mechanical skill.

The CD images appear to be ISO-9660 format, containing piles of “AIX 
backup/restore format file” archives; the floppy images are also identified as 
being that format (no filesystems, just archive content). I’ve seen some stuff 
online that talks about installing from tape using DAT, so it seems like in 
theory I should be able to just push the CD contents to a tape and go.

Can I use the 3.2.0 boot floppy images with a couple of DDS-1 tapes containing 
the files from the 3.2.5 CDs to directly install AIX 3.2.5? In what order 
should the files be put on the tapes? Or do I really need to do a complete 
install of 3.2.0 first?

Another important question: Will I need some sort of key to use the included 
AIXwindows and xlc, or should this stuff just work?

Finally, is there a complete set of post-release patches for AIX 3.2.5 online 
somewhere? I know 3.2.5 itself was primarily a patch roll-up release, I assume 
that with Y2K remediation and other bug fixes in the mid- and late-2000s there 
were a few additional patches released over time.

Yeah, the docs I’ve found say the MMI-110 was sold for the Onyx as Vigrasound 
and used extensively in Discreet Logic installations.

There’s a whole huge chain of acquisitions Vigra went through though (Visicom, 
Titan, L3, Harris) and I fear this information was lost. There are *a lot* of 
jumpers on this card, it’s pretty oldschool VME.

Vigra MMI-210 (VME DSP/audio card) documentation?

[Chris Hanson via cctalk]

I just acquired a Vigra MMI-210 VME DSP/audio card that I’d like to get 
working. Does anyone happen to have manuals or know where I could find them?

The Wayback Machine at the Internet Archive provides some programming 
information 

 so if I can configure the card, I can make it do things.

Unfortunately I have yet to find an installation guide. Since it’s a VME card, 
it has plenty of jumpers that will need to be properly set before it’ll 
actually work.

Anyone have a source for more information, or another place to dig for it?

Re: Data General AViiON AV300D docs?

[Chris Hanson via cctalk]

One thing I’ve done is dump the ROMs in my two AV300D. They’re identical except 
for the last 4 bytes, which I suspect is where their host/Ethernet ID comes 
from.

Unfortunately while the ROM is a JEDEC 1Mbit part, my dump doesn’t look 
coherent, in that there’s no simple ASCII text like appears at boot, and the 
contents at 0 are not proper 88100 instructions. I expect Data General didn’t 
use D[7-0] on the ROM as D[7-0] — and may not have used A[16-0] as A[16-0] 
either. And since my systems have bum power supplies, I can’t boot them and 
dump the ROMs that way.

Anyone have a running AV300 or AV400 system from which you could dump the ROM 
via SCM (the boot monitor)? Then I could compare it with my dump and figure out 
how it’s wired up.

If anyone likes puzzles, here are the last 8 bytes of each system’s ROM:

$ tail -n 1 AV300-10794-01-1AFB.hex 
0001fff0:     7184 f4a2 04fb 67fe

$ tail -n 1 AV300-10794-01-3163.hex 
0001fff0:     7184 f4a2 9cfa f7fc

The ROMs were labeled 1AFB and 3163 respectively. If anyone can see a coherent 
mapping in that, I’d be quite happy. :)

Re: Data General AViiON AV300D docs?

[Chris Hanson via cctalk]

I’ve seen that datageneral.uk at least has a pinout for an Eclipse MV SCSI 
port, which hypothetically might match the AViiON DB-50 SCSI.

In the absence of real docs though, who can say?

Can you post the AViiON AV300D power supply pinout you’ve figured out? Maybe I 
can power on my system with a couple bench supplies or an ATX supply...

Data General AViiON AV300D docs?

[Chris Hanson via cctalk]

Does anyone have AViiON AV300D or related docs? I got a pair that have bum 
power supplies and I’m hoping to find something that will makes servicing them 
easier.

After I get them running, I’ll obviously be looking for software. And a pinout 
for their unique SCSI port, though I hear they can netboot; any details about 
that would be useful too.

Nonetheless, comparing some small amount of lost information to genocide, which 
is a real thing that has happened and is still happening in the world today, 
and which has affected people on the list and those they are close to, is more 
than a bit offensive.

Please be more considerate of this and, as was suggested by the person whose 
correspondence you posted, examine your sense of scale.

I want to do my part in turning the tide and say that I have a serious degree 
of appreciation for all the stuff that you’ve personally done for Lisp Machine 
preservation. Meroko and LambdaDelta are OUTSTANDING work and are a major 
contribution to the field. (Also, the way Meroko simulates every individual bus 
cycle is really something!)

I hope the people who scream at you are the ones who walk away instead. They

Why? That is, what’s the advantage of having 10+ instead of one or two?

The Apple I never did very much, so is there really much to actually show on 
them?

I hope they’re not crowding out anything more interesting.
