Have a working Intel Above Board Plus 8 with 2MB RAM and would like to
populate it to the full 8MB. It will take 120ns or faster 1mbit chips
-- but where can one find that kind of thing nowadays? Are those still
commercially available or am I going to have to scavenge them from
somewhere else?
Manual lists acceptable part numbers like:
Fujitsu MB81C1000P-xx
Hitachi HM511000P-xxS
Mitsubishi M5M41000AP-xx
Motorola M5M511000P-xx
NEC UPD421000C-xx
NMB AAA1M100-xx
OKI M511000RS-xx
Samsung KM41C1000P-xx
TI TMS4C1024-xx
Toshiba TC511000P-xx
...etc but google searches haven't been very fruitful (that is, the
pages returned when I search for IC part numbers don't return vendors
with plain pricing/availability info).
I just want a few tubes of these to populate the board, I'm not looking
for a box of 'em :-) Any pointers?

Anyone collect and/or need parts to the AT&T Unix PC? I've got a pile
of systems I dismantled over a decade ago, and don't really want or know
how to put back together. I bought them "new" as surplus by the pallet
at the time, and about half of them were defective with only displaying
horizontal lines when turned on. The monitors are perfect, I also have
the 20Mb MFM drives and 5.25" drives, as well as the mainboards,
plastics etc. I'm not sure exactly how many and what I have yet, but
checking for interest here. Please reply if these are of interest at all.
Any suggestions on the line problem?

I purchased an HP85B and a few accessories a while back and I've now
come to the conclusion that I am not going to have enough time to do
anything with it. I've verified that the HP85B itself works except for
the tape drive. It has the sticky capstan problem and will need to be
repaired. The printer seems to work though.
The collection includes the following:
HP85B
ROM drawer 82936A with the following ROMs:
- plotter/printer 00085-15002
- matrix 00085-15004
- advanced programming 00085-15005
I also have the following modules:
HP-IB Interface 82937A
Opt 001 Serial Interface 82939A
128K Memory Module 82909A
Of course, it would be great to trade this equipment for something
interesting. At the moment, I'm more interested in music synthesizers
than in classic computers. I don't really expect anyone on this list
to offer that sort of trade but if you just happen to have some old
music stuff laying around that you don't want, I'd love to hear about
it. In any case, I don't really want to pack this stuff up. I live in
Bedford, NH and would be happy to give this equipment to someone who
is willing to come here and pick it up.

I picked up an old 9-track drive and thus far I've been unable to
identify what, precisely, it is.
I have a couple of pictures at: http://yahozna.dyndns.org/scratch/9-track
It has no manufacturer or brand information on it other than an
"Interface Data, Inc." label on the front and a label on the back
indicating that it is Model No. 9946. I can't find any information at
all on the 'net going by this information. I'm guessing that it's a
rebranded drive. It is a desktop unit, horizontally mounted and
self-threading. As far as I can tell from examining it and fooling
around with the front panel buttons it has a SCSI interface and does
1600 and 3200bpi. In the back of the unit are 5 slots, 4 of which are
filled with cards.
It appears to power up fine, but I can't get it to show up on the SCSI
bus when hooked to a PC -- I don't know if the interface is broken or if
there's some configuration I need to do.
Any ideas? I'd like to find a manual for it so I can figure out what it
can do and how to configure it.
Thanks as always,
Josh
Hi David,
I collect old computers and calculators and I have a hp85b, but no
accessoirs. So I am interested, but, yeah, but I am not near, maybe,
if nobody will pick it up, you may think about packing the stuf??
With best regards
Gerhard
Hi all
Just got my hands on the local library's copy of The New Hacker's
Dictionary, 2nd ed (couldn't pass it up even though I've read it
online), and I noticed that the entry for AOS mentions a joke manual
called "How to Goad and Levitate your CHAOS System". Does anybody have
a copy of this? Bitsavers?
