Looking to trade for Emulex UC04 QBus SCSI

[Josh Dersch via cctalk]

Hi all --

In my quest to get my MicroVAX I to do something interesting, I'm looking
for an Emulex UC04 SCSI controller -- this is one of the few MSCP SCSI
devices that I'm aware of that are compatible with the MicroVAX I (the rest
all require a II or later).  I have a nice CMD CQD-200/TM QBus SCSI
controller that I can offer in trade, or I also have a wide variety of
other parts available... please drop me a line if you've got one for trade.

Thanks as always,
Josh

Sure thing! I've set the boards aside as I think I'll likely save them, 
just because they have a local connection - maybe just make a little 
wall-hanging display from them, or something. As usual with stuff that I 
find at the recycler's, it's unfortunate to think that this may have been a 
complete system just a few days ago!

Possibly, although there are quite a few ICs with 1976 and 1977 date codes 
which don't give the impression of being repair parts - I'm not sure what 
the lifespan of the 4200 was. Of course the Wikipedia article is quite 
light on details though, so perhaps there were other models not mentioned, 
or tweaks to the 4200's design to keep it 'current' as time went on.

I've dumped images of the six boards temporarily here:

  (I've no idea what the others are in that photo. Top little one is 
Sperry. There were lots of "industrial" boards in the scrap pile, though - 
CNC control boards and the like - so quite possibly not computer-related at 
all)

Yes, it is red and has a small reader on the front plate. The machine seems 
to be complete (expect the disk drive that is missing the removable platter 
assembly/heads).

I can make some pictures these days.


Hi Christian,

I sent you a message off-list, I think I have a line on some information 
for you. (I'm just mentioning it here too as email doesn't seem to be as 
reliable as it once was, sadly).

CPT boards

[Jules Richardson via cctalk]

I borrowed a pile of scrap 1970s-era PCBs from my local recycler yesterday, 
just to make sure there was nothing important among them before they go off 
for processing. Among them are six boards branded as CPT, which I assume 
(as I'm in MN) is the CPT Corporation that was in Minneapolis.


The double-sided boards are organized in five rows of five ICs, with 44-way 
edge connectors and IC date codes in the 1973-1977 range. I seem to have 
p/n's 910012, 910014, 910015, 910017, 910018 and 910022.


In addition to this there's a smaller board which references "deck 1 heads" 
and "deck 2 heads", and appears to have a p/n of 910025.


Does this ring any bells with anyone? The Wikipedia entry for CPT mentions 
the 'VM' machine in 1976 with dual tape units, so I wonder if they're from 
one of those... if so, I'm curious if there are any surviving intact 
examples out there (or other info, there doesn't appear to be any CPT stuff 
on bitsavers)


cheers

Hallo Christian 
Wie gesagt, ich habe 1974 mit diesen Systemen gearbeitet. Ich würde gerne 
wieder einen Lauf sehen. Ich glaube, du bist in der Nähe von Stuttgart. Ich 
lebte 1969/70 in Maichingen. Ich komme zwar mehrmals im Jahr nach Deutschland, 
aber nach Friedricshafen für einen Urlaub. Was kann ich machen um zu helfen. 
Wenn Sie Zugang zu den ICL-Dokumenten erhalten und sie in Großbritannien sind, 
könnte ich sie scannen.

No, only some non-readable pictures of drawings :-(
I should ask the guy to scan them reasonably.

Datum is known for computer equipment and timing instrumentation. The 
era of such trainers seems a bit late for them, so maybe a different 
part of it.


Obviously the other thing is a trainer board with analog and digital 
bits around the proto area.
