I have a pair of IBM 8" disk drives - they are from an 1980 IBM 5120
I simply won't have the time to give them the attention they deserve for
many years. They seem mechanically ok (they spin) but I don't know much
more about them, or how "universal" they might be as 8" floppy disk drives.
I think I do have to cut them from the transformer they are connected to
(couple thick red wires), but otherwise they have all the original power
harness stuff as well.
Thinking just cost of shipping plus rounded to nearest $10 or $100. They
are about 20lbs (together, and I would like to keep them together - there
is a pin/clip that is used to latch them together, but I do think they can
be separated fairly easily).
Message me if any interest. If you do need/want them for another 5120
project, I can probably include some adapter cards.

So, I was trying to contact "Pete" at vintage-icl-computers.com several
times during the last years. Obiously, the site and/or the person is dead,
no reaction whatever.
I'm hoping that someone on this list might be able to help me:
I still have a Digico Micro 16V computer that, one day, I'd like to
restore. On the ICL site above I can see that they have (had?) the service
manual/schematics for the system, and I would really love to get a scan
(or at least high resolution photos) of these. Does anyone here maybe have
them or can provide me with some pointers? Oh BTW, software (e.g.
papertape images) would be great, too :-)

I am looking for a basic or commercial IMSAI SIO 8080 Comm Program that
uses SIO serial connector 2 for modem communications. Something I can
start from a ROM monitor running from the console running through serial
connector 1.
My system is using the original 8080, I want to avoid the cp/m z80 route.

Looking for information on how to set the jumpers/dip switches on the Xerox ViewBoard (AWPI Bounty) and ViewBoard II.
Apparently there’s one or more hardware installation manuals for these boards, which were also sold as part of the “Network Services for PC” product, so the hardware installation manual for that would presumably also contain this information. Bitsavers has the Network Services for PC software installation manual, which mentions the separate hardware manual(s), but I haven’t yet been able to locate any copies of anything that describes the jumpers/switches.
ok
bear.

Chuck's only saying that because he wasn't invited to "work out."

Maybe this note is off topic but I don't think so: The death of Kevin
Mitnick. His book "Ghost in the Wire" is a classic. Too bad he was a

Hello,
I have a non-functioning VT100. I think I may have isolated the problem to
an Intel 8228 chip (or 88228, the schematic says 8228, the part is marked
88228C). Certainly, the part gets a bit hot and it doesn't seem to be
outputting anything on the I/O W pin (pin 27) despite activity on STSTB (pin
1), DBIN (pin 4) and WR (Pin 3). There is no activity on the HLDA input
though, but I am not sure if that is required because I think the firmware
is just trying to send its status to the keyboard LEDs.
I can find a brief datasheet for the 8228 but it doesn't tell me the logic
for producing the I/O W signal, so I am not sure if it is behaving as it
should. Does anyone have more comprehensive information on how the 8228 is
supposed to work?
I have dumped the ROMs and been able to capture the ROM reads and they match
the disassembled code, so I think the 8080 CPU itself is working.
Thanks
Rob
Hi,

Hello All,
I am wondering if anyone has a private or knows of a mirror for
ftp.compaq.com that is older than 2014? All the ones I have found online,
including the file at archive.org, are from 2014. By then a number of files
and directories had been purged e.g. "/pub/supportinformation/techpubs" and
"softlib1". I am looking for some old documentation and firmware for Compaq
switches and Tape Libraries but if anyone has a full set of files I am happy
to add them to a mirror. TIA!
-Ali
