The RX-50 is a 80-track version of the 360k IBM-PC 40 track floppies.
It was formatted at 10 sectors per track with smaller inter-sector padding
bytes than normal. It uses the same rotation rate and data transfer rate
as the older drive, which is different than the AT formatted floppies
use.

So RX-50's use 250k transfer rate, 80 tracks, usually 1 side (though
the controller supports 2 sides, the physical RX-50's don't). 512 byte
sectors. 16 bytes between sectors (as opposed to either 35 or 42
for IBM-PC floppies) with 46 bytes format gap (as opposed to 80
for IBM-PC floppies). This is how you got 400k out of a single sided
80 tracked disk. IIRC, the rotation rate is 300 for RX-50 and old
IBM-PC vs 350 for the IBM-AT drive. All these niggling differences
cause problems...

> I'll look deeper into those issues when we find some media.

One thing to avoid is disks with hub-rings. On the Rainbow they
caused nothing but grief. You might not be able to at this late date,
but if you have a choice.

Something like

http://www.ebay.com/itm/NEW-BOX-OF-10-MAXELL-MD1-DD-SINGLE-SIDED-DOUBLE-DENSITY-5-1-4-FLOPPY-DISKS/131848023428

may work. These are single sided double density but list 96tpi, which
means they will go to 80 tracks easily and should be able to
be formatted in the Rainbow for use on the PDP-11. The 11's
controller, like I said, won't format.

Hope this helps.

The controller for the PDP-11 can't format them. The Rainbow can format
them w/o problems. You won't be able to use PC formatted 5.25" drives.
The IBM AT 1.2MB floppies can be reformatted and perform adequately,
but it's much better to use the proper quad density disks. By "adequately"
I mean "in a pinch until you can get something better because the data
is at risk" Some of the disks I used back in the day worked OK, while
others didn't work so well.

If you are talking about he ALU CNTL ROM on page 40 of the PDF and the
truth table for it listed on page 48 of the PDF the part is listed as
DM8598-AD, where a DM8598 is a 256-bit (32x8) tri-state bipolar mask
ROM.

Some substitute T.S. PROMs include the Signetics 82S123, AMD 27S19,

My BP Microsystems programmers support the 82S123 and 27S19, but maybe
not the DM74S288.

Many/most of the common bipolar fusible proms are Schottky class, so are quite 
fast.
Take a look at  74S188 / 74S288 as a starting point. Down in the 20-30ns range.

Are there pull-up resistors anywhere along the output/data lines? If not, it is 
more likely a tri-state device.

Probably more than you want to bother with, but blowing fusible proms generally 
isn't all that difficult, I've hacked a burner on a breadboard with an RPi 
(substitute other microcontroller as desired), 2-3 common TTL ICs and a few 
transistors.

contemplating selling my VT52

2016-06-24 Thread rescue


I've been saving the VT52 I've owned for years (used it with a modem 
back in the late 80s to dial into school) with the thought of paring it 
up with a PDP-8/E, PDP-8/F, or PDP-8/M  but I don't know that the 
PDP-8 train will ever stop here.  I've come close a couple of times, but 
have either missed the train on a good deal, or not been in a position 
to stomach the pricing some of them fetch.


So, I'm contemplating selling the VT-52.  It has age typical wear, but 
last time it was powered on, it was working.  There was a touchy 
connection that would act up once in a while requiring a tap on the side 
to bring it back around (something in the video connection no doubt).  I 
never dug into it to resolve it 100%, as it didn't happen often, and a 
'love tap' on the right side always brought it around.


I'd like to hang onto it, but it is big.

I'm entertaining offers which might sway my decision to keep/sell it.  
I'm located close to the intersection of Sharon, Easton, and Stoughton, 
MA.
I don't think shipping is an option, unless your willing to pay, and 
take the risk on something like this being transported.  If I can get a 
big enough box, I can pack it well but I'd prefer not to do it due 
to the risks involved.


Keep VT52 in the subject line of any e-mail you send so I can find it 
easier.  Sometimes I may only check mail here once a week, so if you are 
inquiring and don't hear from me for a while, no fear, I'll get around 
to you.

Thanks for the info, Don -- learning a lot about this stuff as I go...

I had wondered if the part might have been a mask ROM rather than a 
PROM.  And wrt. timing, I was certainly mistaken to call the nominal 
interval between the clock pulses a microcycle.


So after staring at the flows and prints a little more closely, it looks 
to me now like the IR will be latched at FET.10 t6 (which is really 
IRD.00 t1?) then there is the rest of intervening IRD.00 during which 
time control signals can propagate to and through decode logic and the 
subsidiary ROM and ALU, then the ALU results are latched into the 
shifter at EXC.80 t2 or EXC.90 t2.  So that's a solid 150ns there minimally?


From the prints, it looks like this is an open-collector part -- I

ACARD ARS-2000SUP versus SCSI2SD - round 1

2016-06-24 Thread Swift Griggs

Tested using "Raw block speed" test in LIDO 7 under MacOS:

[SCSI2SD v5]
  READ: 891 KB/s 
 WRITE: 728 KB/s 

[ACARD ARS-2000SUP]

  READ: 1621 KB/s
 WRITE: 1277 KB/s

More info:

The ACARD device contains a Samsung 850 Pro 128G SSD. The SCSI2SD contains 
a Samsung Pro+ 64GB micro SD and is running firmware v4.6, IIRC. Both are 
were attached to a Quadra 700 Macintosh running System 8.1 with 68 megs of 
RAM (4 onboard + 64MB in 16MB SIMMS, the max on the Quadra 700). I had 
them hooked up at the same time so I could use one to partition the other. 
The hard disk "driver" was the one provided by LIDO, but I also tried 
LaCie SilverLining 5's driver as well, but the performace was slightly 
worse. I tested in LIDO using it's raw speed test feature. It's probably 
only a rough measure of sequential speed. I just tested three times and 
averaged the results, but it was within just a few KB/s each time.

Once I'm done I'll hook both of these up to a FreeBSD box, dd off full 
backups, then start over again and try with ZFS under FreeBSD via a PCI 
SCSI controller. Then again under IRIX if I still have the energy. I'll 
give some results from 'fio' or 'iozone' under FreeBSD. Those will be a 
lot more detailed and break down sequential versus random results and show 
the results of various other permutations.

I'd also like to test the SCSI2SD v6, but I can't get my hands on one, 
yet. The only place that talks about the v6 is the codesrc wiki and the 
American ebay retailer seems to only have the v5.0. I'll wait, I guess.

Re: Grey Wall (VMS) available (Retrieving things from another zip code, several removed)

2016-06-24 Thread Jim Stephens


It is just that he is independently employeed, and makes these trips 
maybe every one or two months to recover someone, frequently for another 
agent in one of the 5 or so counties he covers.  It is hard to find 
people that can just drop things and go, but in his business, others out 
of his office can cover his reportees, and if someone skips the process 
of going out to knock is done by someone he works with if he is away.


So he is a unique resource in that regard, and because he is a bonded 
person for his work, I feel that is a plus so you can rely on something 
showing up, rather than a pig in a poke (and just have Jim's word that 
his cousin is a good dude).


Anyway, if someone wants that, or for that matter in the future if 
something shows up, he and his friends could round up and drive a load 
for you at cost+ basis.


My current Kansas City friend who is reliable is currently swamped with 
A/C business, which as you might guess has his feet glued to the KC 
area.  So if something in that area was needed, wait till the weather 
cools off and he might be available.


might be useful to have a thread with people who know relatives, friends 
or the like to do rescues to look back at when you see the odd large 
load that you'd like but in the wrong zip code.


thanks
Jim

options for replacing failed small ROMs in PDP-11

2016-06-24 Thread Fritz Mueller

Hi All,

In bringing up and debugging my PDP 11/45, I found that one of my GRA 
(M8101) spares has a failed ALU subsidiary ROM.  It's a pretty standard 
little 32x8 ROM in a 16-pin DIP, and the truth table is in the 11/45 
print set.


I wonder what the replacement options are for parts like these?  In 
particular, given the 30ns micro-cycle on the KB11-A, and the fact that 
the propagation time for the ALU downstream of this is roughly 20ns on 
its own, I'd be worried that an off-the-shelf bipolar PROM might be too 
slow here.


I'm still a little slow on reading the microcode flows, so its not clear 
to me exactly how many micro-cycles there are on the critical path for 
the E-class instructions where this ROM is used.  Maybe its not an issue.


Anybody every try replacing one of these with a bipolar PROM?  Any other 
suggestions for how to repair parts like these?


cheers,
 --FritzM.

KM11 uPB question

2016-06-24 Thread Fritz Mueller

Hey folks,

While working on my 11/45, I built up a KM11 replica based on Tom Uban's 
ExpressPCB layout.  I noticed the following behavior when trying to use 
it in uPB mode on my KB11-A CPU:


 * If I set up uPB, set KM11 S1 on and S2 off, and resume execution,
   the breakpoint fails to stop the processor
 * BUT, if I depress and *hold* CONT, while it is held down the CPU
   will be held in T2 on the target microword
 * If I then reach over and flip on S2 before releasing CONT I can hold
   the machine there in T2

Documentation on the KM11 seems to imply that the machine should just 
stop at the target state holding in T2 without having to do the 
holding-down-CONT-while-flipping-on-S2 thing.


I was wondering if this was an oddity of my KM11, my CPU, or is that 
just the way uPB mode works on these things?


thanks,
--FritzM.

10MB is better than 0MB.  I'll mention it to him.  In the meantime,

Yes, but you need the right type of PC floppy because RX50 are
single-sided and 80 tpi and 10 sectors-per-track (400K on one side).
I'm sure there are FAQs and instructions all over about the process...
I just don't recall off the top of my head which keywords to shop for
that are merely good enough for TRS-80s and C-64s and which will do
for RX50s.  Single Sided Single Density will not cut it, not that uber
cheap floppies abound these days (Elephant?  BASF?  Only if you like
cleaning your heads between each diskette).

Back in the day, I mostly used raw RT-11, but I did dabble on a

of boxes, I do plan to dig out the TSX+ stuff and play with it.

Re: Tektronix terminals and terminals in general (Re: CDC 6600 - Why so awesome?)

2016-06-24 Thread Pete Lancashire
Not Tek but I've seen directly two instances where simple terminal
UI's where very much missed by the end users.

The one I remember the most was a nationwide auto parts company who I
wont mention who. The stores used
80x25 ASCII terminals with forms and fields and just about every
function key did something.

Once the UI was learned watching a counter person was quite amazing,
someone with an account would walk
in ask for a price on something and if say ok you would in less time
it would take for one to move a mouse and
click a button on a modern UI, a dot matrix printer had printed out
the three part NCR paper invoice. Other then
going to get the part and rip the 'holes' off the invoice paper the
guys hands never left the keyboard.

After conversion that simple terminal became a PC with a mouse, a
fancy gui front end, blue screens of death,
virus scanners, and software contract for the O/S, the fancy gui
client, etc. etc.

Not to mention pissed off customer because it went from a few seconds
hit half a dozen of F keys, hit the tab
key a few times to a good dozen mouse moves, clicks, open windows,
wait for a megabyte or two of data
to go back and forth, reboot the PC in the back room because the
Printer Spool crashed, and ..

I don't need printers (I have *lots*, but the old LP25 did not make
the cut when I was clearing out my office in 1993...), but I was
making the suggestion to Mark that there are many options he could
explore if he's willing to make a converter box and not just run a
DC37 cable from a line printer to his interface.  Sure, the right
printer is just a passive cable away from working, but line printers
can be expensive to ship and hard to maintain and it's not the only
solution.

A crate will protect better against being squished by other cargo, but it's 
still up to the shipper to know how to secure the item inside well enough to 
withstand shock. A fully assembled heavy thing inside a fragile plastic case 
may not make it intact no matter how good the padding is.

It's amazing how much stuff UPS had managed to destroy "for" me, also. 
It's like them drop the boxes off a crane or something. 

 I wish one of these shippers would develop a glass-coke-bottle style 
business model. You ask for a secure container and they can either be 
delivered for $$$ or you can pick them up. The containers should be made 
from real materials (wood or something strong with nice foam suspension or 
padding with FRAGILE printed all over them). When a buyer decides they 
want this service, they pay a small deposit fee which is refunded when 
they put the empty container out by the street for the shipper to pick up 
the next day. Then they refund your deposit.

I'd definitely pay extra for that for many delicate items. Maybe someone 
already does that sort of thing but it's just not the kind of thing I've 
ever heard of from OOOPS, Federal Compress, or USPS.

Sure you can pay extra to insure your items, but what if they were super 
hard to get?

That is very true. I could use one of those large black plastic pieces that

HP 264X terminals on the other hand, do ship well because they are most
definitely built like a tank. That being said, I did have one shipped to me
a few years back (posted pictures to the list) that a shipper managed to
completely destroy. They put it in a box that was twice the size of the

Most definitely. Having dealt with a *lot* of terminals, and had many
of them shipped to me - I have had at least two VT100's broken in
shipping. The problem is that there isn't much holding that upper
housing on, and it gets pretty brittle with age. Even a well packed
one has a good chance of being broken in transit. Other terminals that
are difficult to ship include the Zenith Z19 - the picture tube tends
to break the posts that hold it in - that plastic has gotten kind of
brittle.

The VT50 series, while big and bulky, is fairly sturdy and shippable,
but the sheer size is a real problem.

I don't even want to think about shipping a VT05. That thing is heavy,
deep, and fragile.

That reminds me vaguely of RIP at the end of the BBS era. It probably 
could do a partial-refresh/erase, but if you watched it "paint" images, 
that's how it appeared. I was glad that the Internet-era came along, but 
it's sad RIP didn't come along earlier. 

I also remember some kind of BBS terminal emulator that I only saw over 
someone's shoulder. It was for the Amiga and appeared that it could 
transmit/receive sprite-based graphics over the modem connection. I just 
remember watching a friend of a friend connect to a BBS overseas and I 
they had some kind of welcome screen with a little sprite-based unicorn 
running across the screen. I dunno, maybe it was a rigged demo, but it

Yes.  They are nice.  I have one (Qbus interface).  They are not as
abundant, however.

(but I was thinking mine had a pair of Tandon TM848s - maybe that's
just my Dataram PDP-11 clone - that one could also format floppies via
ROM on the 3rd-party controller)

It can be tough to ship CRTs (step 1, don't put them in a tiny box...)

I don't get out to Seattle, but if you drive out to a VCFmw or VCFe
some time, I've been known to bring dumb terminals to sell.  I don't
want to ship them either.

None, unless you count the fact that both are green and both use electrons.

The Tek 401x series displays are terminals (connected by a serial port).  They 
use storage CRT technology to create a persistent image (no refresh).  They do 
dot matrix ASCII text, line drawing, and have a crosshair cursor for input.  
They use ASCII based text communication, at 9600 baud (I think they go that 
high).  The 4010 is rather a small tube, 24x80 characters; some other models 
are much larger and can do quite impressive graphics at fairly moderate cost by 
the standards of the time (mid 1970s).

The CDC 6000 series console (Data Display Co. DD60) showed up about 10 years 
earlier.  It's essentially a dual oscilloscope with X/Y input -- like typical 
oscilloscopes it uses electrostatic deflection.  The display itself accepts 9 
bit X and Y coordinates, plus analog X/Y offset signals that are used to 
produce the character outlines, a size selection signal (small/medium/large) 
and a left or right intensify signal.  The X/Y deflection signals are applied 
to both tubes, but the intensify signal controls which of the two lights up.  
In theory you could light up both simultaneously; the CDC controllers would not 
do that.  There's also a keyboard, with a 6 bit data signal plus key up/down 
signals.

The 6612 or 6602 controller ("synchronizer" in 6000 terminology) connects a 
6000 I/O channel to the DD60 (or, for some models, to a pair of DD60s).  It 
interprets commands to produce the X/Y position signals, advances X after each 
character, and converts character data into the X/Y offset waveforms.  The 
waveform generator is essentially a counter feeding a ROM which feeds a set of 
D/A converters.  In the 170 series, it was done that way, but in the 6000 
series display controller, the waveform generation uses a large complex 
collection of gates instead of a ROM.  Why, I'm not sure.  A possible answer is 
that a sufficiently fast ROM (100 ns lookup time) wasn't available in the early 
1960s.  The controller, when in keyboard input mode, would read the keyboard 
lines and deliver the data (or 0 meaning no key down) to the PPU.  No rollover, 
which meant that typing fast required some practice.

Since the DD60/6612 hardware had no refresh machinery at all, the driving 
software would do the refreshing.  This made the display very dynamic.  By 
contrast, a Tex 401x is a storage tube, which puts it at the other extreme: 
once you draw a character or line, it would stay without any further action.  
You can't erase it; the only erase available is a full screen erase.

That still sounds great! I'd also love a DEC terminal of some kind... I got
rid of a VT-100 years ago and regret it. Some of the AT machines were
interesting too!

Just don't tell them, that they do ;-)

If you really think about it, the terminals just got faster and
got more colors. (and you call them smartphone, thin clinet, tablet, win 
PC, ...)

Otherwise:
a.) most data is somewhere in the cloud (before it was called mainframe)
b.) a lot of applications are running in the cloud (before, mainframe)
c.) you connect now via wireless internet (before: modem)

You'd be better off looking for a DSD, which also had PDP-8, Q/Unibus
interfaces. They use Shugart drives, and can format disks.

I was just looking at those things, too! I've always liked Tektronix and 
these are wonderful. I found some picture of people doing what appeared to 
be CAD on them. There are descriptions of all kinds of creative things 
being done with them.

About 15 years ago I did some work for a lumberyard company. They had 
the most consistent IT setup I've ever seen. They had very few actual 
computers anywhere. 95% of the company used terminals fed off serial 
MUXes tied over 56k or 128k leased lines back to their corporate 
headquarters. They used portable battery-powered hand scanners that 
plugged into the terminals' keyboard interface, IIRC. Those were for 
scanning their inventory. I noticed:

* They had almost no IT staff, yet things ran pretty smooth.

* They never had viruses.

* Replacing "workstations" (terminals with more access to their business 
  apps) took about 10 minutes.

* They had some weird office automation package (word processor, time 
  management, spreadsheet, etc..) I'd never seen before that reminded me a 
  bit of that one office product from DEC for VMS (I can't remember the 
  name, but I think it was written in DCL). I don't know enough about VMS. 
  The bosses and admin assistants ran that and they absolutely loved it. 
  It was very fast and the kind of thing were once you memorized the 
  keystrokes you could just fly through it.

* They had a coder who wrote some really cool blackberry-like features for
  the Palm Pilot. They could sync all kinds of business related stuff from 
  their Unix boxes (mail, order information, inventory, etc). The bosses 
  all had those. 

It's the only place I ever saw, besides the (extremely well funded and 
very nice) Don Harrington Library consortium that was able to really get 
some mileage from a hub-and-spoke, terminal based, WAN distributed, highly 
integrated, centralized system. From a sysadmin perspective, it seems like 
it makes a lot of sense. Just cluster a few robust systems and tie 
everything you can into them once you've got your confidence up!

However, I think most folks these days would faint if they were forced to 
work on a terminal. 

1. They couldn't play minesweeper when they got bored. 
2. They couldn't refresh Twitter & Facebook every 5 seconds.
3. They couldn't run an IM client.
4. They'd have to actually read the screen. No icons. 
5. How would they do their jobs as users and infect the thing with 
   crapware and viruses?

I often setup terminals on my desktop as "extra heads" to display logs or 
monitoring information, or sometimes use them for debug output for coding 
projects etc... When I'm working at a big corporation it absolutely freaks 
just about everyone out and their reactions are mostly quite annoying. It 
pains me to hear people use the words "text" like it's a curseword. Plus, 
they also just stand there stunned and say "but but that's OLD!" 
as if I were violating some local ordnance not to poop on my desk. 

I smile when I go to the auto parts store and they are still using 
terminals. Never say die! 

I think terminals were, and actually still *are* cool. Computers might be 
cheap now, but that doesn't mean that having centralized control with 
users on terminals isn't still useful in many instances/situations.
