Re: Local Pickup of PDP-11 Qbus Hardware, Software and Manuals

[Brian Adams]

Hey there, I¹m in Toronto and have an interest in DEC / PDP hardware.

I don¹t have a whole lot of space unfortunately, but I could probably help
you with a BA23 unit and a terminal.

If possible, would it be possible for me to visit and take a look? Not
sure exactly where you¹re located.

My number is (437) 345-6530

Before you ask, 437 is a new area code assigned to the Toronto area
because the supply of 647 numbers is dwindling (they might even be
exhausted at this point).

Thanks!

There was a seller on ebay who had a set of the pre-made keyboard key pads
for sale...anyone here selling these?  Yes I could make my own, I have gone
through the process, but I'd like to buy a set or two as I have a few
keyboards to repair.  it's a time consuming process.
Thanks in advance.

You can not "align it properly" without an alignment disk.
But, you can probably get it close enough to its prior alignment to be

Re: Zenith Z160 Luggable PC aquired

I'm not sure specifically on the z-160 but my z-150 had it (iirc and it's been 
a while ctrl+alt+ins or ctrl+alt+enter) I think put you in the diagnostic rom 
which had a debugger.
Curiously though i dont know if that is a hardware function or a feature of 
zdos?

SGI Indigo Update

[ethan]

I started updating my blog with (hopefully useful) information.

I did a write up on the SGI Indigo so far and will update it with future 
findings. It's at http://ethan.757.org/?p=32


I made a list of all the tantulum SMD capacitors of the style of the one 
that fried. I think I figured out digikey part numbers for most (And 
published the sizes I measured of the caps.)


If the cap that fried belongs to the audio section, I was thinking maybe 
those components use negative PSU voltages (op-amps, DACs) so maybe the 
PSU is doing something funky. Finding a pinout for the Indigo PSU might 
take a little bit of work -- but since I have mine apart I should be able 
to document some of it.


So many projects!

RE: Megatek Series 7000 Graphics System?

[Mark Green]

Megatek was one of the main high end graphics vendors in the 1970s and early
1980s, the other one was Evans and Sutherland.  They were both largely
knocked out of the market when SGI came along.  I always wanted one, but my
employers could never afford something that high end.  Internally they are
vector displays, they connected to a host computer to download the display
program to produce the graphics.  One of the interesting features of some of
the later models is that they could be hooked up to a vector or raster
display.  I think they could also support both from the same controller.
Megatek saw that the world was going raster, and they moved in that
direction a little too late.  A very nice architecture.  I believe one of
the early versions of Foley and van Dam has a high level description of the
architecture.  I've searched the web multiple times looking for information
on them, but had little luck.

If the one that you have has raster output there is a good chance that you
could get a modern monitor to display the output.  If it has vector output
you really need the display unit.  They are less likely to survive than the
other components unfortunately.  

By the way, if anyone on the list has Evans and Sutherland documentation I
would be very interested in talking to them.  I have an E picture system
that I would like to get fully functional again, but I have no documentation
for it.

Local Pickup of PDP-11 Qbus Hardware, Software and Manuals

[Jerome H. Fine]

As I find that there is less and less need for my PDP-11 Qbus Hardware,
Software and Manuals, I wish to determine if there is any interest in my
local area to transfer everything using local pickup in Toronto.

As some of you know, my interest is in RT-11 on the PDP-11 and I have
been doing it since the 1970s.  If there is sufficient interest to come 
by and

do a local pickup, then please send me an e-mail with a local phone number
in area code 416 or 647 (or 905 which can be called locally from 416) so
we can arrange something.

The total volume of everything, including probably at least 30% junk, is
probably ten to twenty cubic meters (100 to 200 cubic feet), so there
will need to be some sorting done along the way.  As for hardware,
the collection is mostly BA23 and BA123 boxes with PDP-11/73
and one PDP-11/83 along with assorted Qbus boards.  There are
many VT100, VT220 and VT320 terminals as well.  There are many
PDP-11 manuals and DOC sets for RT-11.

I download my e-mails rarely these days, so it may take even a few weeks
before I reply.

I think that the Z160 is based closely enough to the Z100 that

In stock configuration the video is CGA, so it is POSSIBLE that connecting 
a composite monitor (if the Z160 has the connector) might not require any 
additional software.
Do not connect an MDA monitor unless you are sure that the sync frequency

Re: HP1631D Logic Analyzer..Software???

[Glen Slick]

I acquired an HP 1630D a couple of days ago. It is a 2311A serial
number prefix with the expected 01630-66512 version CPU board. It
originally had the "HP1630 Software, Tue, 26 Oct 1982, 16:31"
01630-80008 - 01630-80015 version firmware 2764 EPROM set installed.
That is the version with HP-IL tape storage support.

I burned a "HP1631 Software, Mon, 14 Oct 1985" 01630-80054 -
01630-80061 version firmware 27128 EPROM set and swapped those in
place of the original firmware EPROMs and now have HP-IB disk storage
support.

The only two 1630 config/IA floppies I currently have are
10304-13012 8085 Config / Inverse Assembler
10342-13012 HP-IB, RS-232C/V.24, RS-442 Config / Inverse Assembler

I used HPDir to dup the two floppies from a physical 9121D drive into
.HPI image files, then verified that the 1630D can access those .HPI
image files loaded into HPDrive to emulate a 9121D drive.

I can send those two .HPI image files to anyone who wants them.

Introduction and Novell UnixWare 2.02 problem

[Tom Manos]

Hi, I'm new to this list, but I've been on the rescue and geeks list
for many years.

I'm kind of a Unix guy, but unlike many of you, I learned mostly on
AT Unix. I started using Unix in the early '80s and ran a public
access Unix system from roughly '87 to '92, when it turned into a real
ISP, which got to be quite large. We mostly used Dec Alpha stuff then.

I couldn't afford a Sun workstation in the '80s, so ran SVR2/3/4 on
Intel hardware, and even that was expensive. These were the days of
1200bps Smartmodems (which were also pricey) and terminal or BBS
interfaces. The Unix systems provided Usenet, real email and even
rudimentary file transfer via UUCP.

I still love the terminal based interface and won't run X on my old
hardware. I'm really a Unix Philosophy sort of guy. Small tools,
filters, and all the rest.

So, on to my question: I run UnixWare 2.02 on a couple of older
machines here at home. It is a pretty standard version of SVR4 if you
don't install the Netware stuff. It is very stable and runs great on
the older Pentium hardware I have. Recently I build a dual processor
P3 system with an ASUS P2B-D MB so I could run SVR4-MP, which runs
wonderfully. These are SCSI systems with SCSI2SD boards used as disk
drives. Old 50 pin SCSI drives are getting more expensive and have
questionable longevity.

I want to build some emergency rescue diskettes and tapes, and my
problem is that the 3.5" floppy will not format a diskette under
UnixWare. I've tried everything I can think of. The drive is good (I
can format a DOS floppy when I boot up DOS), and the diskettes are
known good.

When I use the format command on the raw disk device, I get the following:

# /usr/sbin/format -V /dev/rdsk/f03dt
formatting.
UX:format: ERROR: Formatted 0 out of 160 tracks:
Failed in write/read/compare verification on track 0.

Doing so without the -V verification just appears to merrily format
the diskette, but it's not formatted.

The device(s) I'm using are:

crw-rw-rw-5 root sys1,112 Feb 14  1995 /dev/rdsk/f03ht
or
crw-rw-rw-5 root sys1,112 Feb 14  1995 /dev/rdsk/f03h

Both yield the same error.

I'm thinking this must be a device driver problem, but i"m out of my
league here.

Anybody have an idea what's going on and how to fix it?

Oh, and sorry for the long post. I thought it might be polite to
introduce myself.

TIA,
Tom

Thanks for that suggestion. I tried some glue from a bicycle puncture repair
kit and it did indeed work very well.

Re: for sale/trade: big list of both old and (relatively) new, deadline: end of November (ideally)

All the SGI systems and most parts (except the DMediaPro DM10 IEEE-1394a 
FireWire/i.Link board[s]), the DEC Multia/UDB, APC Smart-UPS 3000 XLM, 
Wacom Intuos ADB tablets, IBM System x rack rails, IBM System x (x346) 
PSUs, various cables, etc. have been sold or scrapped, the AlphaServer 
(e.g. DS15) memory is spoken for, as is the DS15 PCI audio option, but 
other things are for the time being still available, but won't be for 
much longer.

Excellent news!  I eagerly look forward to this so I can get my 9825T talking 
to my 9895A!  If you spin a PC board, I will be willing to purchase one or two 
if you end up with extras or are willing to coordinate an order.

Compaq TSZ07

[Ali]

Hello All,

I know the TSZ07 is a DEC model 9 track tape drive. I've seen references to a 
Compaq one as well. I am guessing this probably occurred after Compaq acquired 
DEC and simply rebranded the drive. I am wondering does anyone own or have 
pictures of the Compaq branded one (i.e. w/ a Compaq logo etc...)? Thanks.
