Haven't got a lot of money to drop on classic computer goodness, but I
do brew a varied and drinkable selection of beers.
OK - here are some things I'm trying to get hold of.
Cable to go between two RL02 drives
Serial printer, ideally a DECWriter of some sort ('cos it's to go on my
PDP11)
VAXStation SCSI cable (with the funny half-pitch pins)
Some kind of CP/M box, with a reasonably well-documented disk controller
and console (can be internal, or an external serial terminal - I'm not
bothered).
Will swap for beer or toys, can collect.
Gordon.
Well, it appears to be a good moment to place my wish-list. For europeans
providers mostly, even when I don't dismiss offers from the other side of
the Atlantic ;-)
My first field of collection is over old unix-ish systems, in particular
Sun, AT&T and DEC systems, but I should like to put a hand in other more
"exotic" systems, like Masscomp, Sequent's Pentium and 486 systems, Data
General, Tandem...
The second is about old CP/M systems. One Morrow, Cromenco, or S100 system
(capable of use 8", 5"25 and Hard Disk) would be fine. And one Apple II with
CP/M board installed (trying to kill two birds with one shot). Not much,
isn't so ?
The third is about old IBM PC items, mostly peripherals (One Corvus device,
for example) that could be used too with the CP/M systems, but software too.
I have already over 100 original software packages, but recentrly I've obtained
more space to store this items.
In the DEC (more or less) side:
* One Decwriter, plus cable set
* A couple of RL02 units, plus cable set
* A couple of Pertec Units, Cipher or TSV05 type
* Two 42" Dec racks
* One RX02 unit
* One MFM HD-FD controller for Qbus
* One Teletype
* One serial Paper Tape reader-puncher
* One Unibus PDP-11
* One PDP/8-E
* One Decmate
* One GT-40 terminal
* One VT52 terminal
* Some VT10x terminals, like 103, 125 and so on.
In the AT&T side:
* 3B2/400 spares (boards) and software. Docs are welcome but I have a lot
already.
* One 3B1, operative, with lan capabilities, plus software and docs.
* One 3B2 "high" (600, 1000, etc)
* One AT&T/NCR StarServer
In the Sun side:
* One Sun1 system
* One Sun2 system
* Monitors for Sun3 monochrome systems. Eizo Flexscan 6500 perhaps ?
* Keyboard/Mouse for Sun3
* Some kind of "High" Sun3 system(s)
FInally, I should like to obtain in some moment of my life one HP-1000 or
2100, and one HP-3000 of the old-style. This one was the first computer where
I worked. I had the instruction to mount the disk of work and use the Cobol
Compiler.

If anything they are both generic S100 crates. Most S100 systems needed at
least two serial ports. One for the console and often if there was a modem
one for that. In my case I used a DEC 100 printer which happens to be a
serial interface rather than parallel.
Those that did run multiuser often had many more than two ports. I have
a few S100 4 port cards and have seen systems easily capable of running
8 or more users.
If anything S100 was the PC of the era in the sense that there wer plenty
of crate (bus and power) vendors and a plethora of board suppliers. At
times mixing and matching was like PCs post XT era in that most boards
nearly worked but there were variantion on interpretation on bus standard.
The Apple and SS50 bus machines (6800 and 6809) were also common too in
the way of machines with some kind of bus that multiple things could
be plugged into. In Europe there was ECB bus and I suspect others.
So in most cases S100 implies generic system but little beyond that.
For example for S100 the cpu list included everything up to
and including 386s!
By specifiying a vendor of S100 system we are usually talking about
box/CPU/FDC as an agragate system from vendor. It was common to
have memory from the same of multiple vendors and possibly added IO.
A pure single vendor S100 system is sometimes uncommon. It just so
happens that NS* marketed the Horizon as complete systems that were
business ready and modestly priced as a complete hardware and software
package.

Hi,
I recently got my NorthStar Advantage up and working, it had suffered when I
first powered it on with a failed tantalum capacitor on a SIO board. I
didn't originally spot the soot and debris as the machine has two SIO boards
and of course the failed cap was on the hidden board :-) Followed advice on
earlier thread 'Smoke on the Horizon', I replaced the 6 tantalums with new
ones. I also now have a variac and the PSU was bought up gradually, no
problems at all on that side.
It now boots into either CP/M or NDOS 1.0.0, and on the latter it has GBASIC
which is the extended Basic supporting the wonderful graphics ability of
this machine.
Unfortunately GBASIC often crashes with a 'RAM Parity Error' message, I
guess most of the RAM is OK else it wouldn't boot. The Technical Manual
refers to the dealers Diagnostic Diskette, and shows a series of tests to
identify faulty RAM chip. I don't wish to try and re-seat all the chips as
when I tried this on my Pet it has failed to display anything since (another
pending repair project).
I've just bought some hard sector floppies, so can send a blank floppy to
anyone who can copy the diagnostic disk for me, I would be very grateful.
Regards,
John
I thought someone posted to the list recently wanting a DSD drive (RX01/02
replacement) for their PDP11. Whoever it was, please contact me offlist.

Many thanks to those of you who have commented on this thread!
I probably have at least a couple dozen IBM PCs, XTs, ATs, Convertibles,
Jrs, PS/2s, RT, etc. along with a fairly complete set of IBM technical
documentation for them. I've also got quite a few IBM cards and
motherboards, so these are not something I am looking to get rid of.
Tony mentioned the IBM professional graphics card and monitor, and that
is something I would like to get hooked up just to see how it looks.
AFAIK though, I only have one PGA monitor and card.

Ah yes, do you know how to store tighter :)? I've moved out/tossed
perhaps 1000 - 2000 cubic feet of stuff, and can kind of see a
difference. Another thought we've had here is to sell tickets at maybe
$20.00 a pop for people to "tour" certain areas of the house/garage/etc.
We figure the biggest market would be to people whose wives complain
about the amount of stuff *they* have :).

Hi gang:
I have 3 cases of tractor feed fan-fold paper for postage if anyone is
interested.
This is the 9 1/2 X 11 NOT 8 1/2...cannot be used in TTY printers...
Some with 1/2" greenbar, and some plain.
If you are interested please contact me off line.
If no one wants it, it will go to the landfill.
73, Tom

AFAIK, that was a standard mod, at least for anyone doing any
development work. I remember working on a clients machine that still had
the reset switch in the back ... what a pain!!!
Can someone recommend a freeware 6802 disassembler. The Micro General
postal scale that I have (circa 1983) has a 6802 processor with five
27c64 Eproms. I've copied the eprom binarys to disk, and now want to see
what the program does. It has lost its calibration (the backup battery
died) and upon replacing the battery, it is calling for a calibration
and I've not been able to find any informaton on the web regarding how
to calibrate the scale. So it looks like time to do it the hard way :).
Thanks!
