Hi all,
I have a microVAX 3900 in a small cabinet (approx 90 cm deep, 105 cm high)
that is taking up place that I really need. AFAIK, the 3900 is in working
order,
and I have also an RF215 (?) smallish tower with some disks in it. I need to
check if you are interested. If you don't want the cabinet, you can get the
PSU and the 3900 "crate", but given their weight, I am not going to ship it!
That would get costly, but you could try to talk me into it :-)
Contact me offlist (gooi AT oce DOT nl).

Hi all,
I have a HSC70 in a small cabinet (approx 90 cm deep, 105 cm high)
that is taking up place that I really need. It's too crowdy.
AFAIK, the HSC70 is in working order, and a tech told me that it is
fairly equipped internally. I can't tell, I don't know anything of
the HSC70. If somebody is interested, I can rip boards etc, before
it goes to the trash :-( Somebody who wants the whole thing,
comes first, as I am still hoping it can have a good "life".
Contact me offlist (gooi AT oce DOT nl).

Marginally on-topic (?) -- the watchman is "old", and
the intended application is a "computer" ;-)
I'm looking for a working Sony WATCHman (NOT *walk*man)
for a wearable I am hacking together. Doesn't need
to be in good cosmetic shape since I will disembowel
it, regardless...
Apologies if I have *stretched* the on-topic-ness on
this one :-(
I don't suppose anyone can help, but I'll ask anyway.
I have an IBM 836 Keypunch, which is similar to an
026 keypunch but has a patch panel in a pedestal to
the left of the users knees.
It also has three 40 pin connectors on the back panel.
Does anyone know the capabilities of these? Where
can I get matching plugs? The logic levels are presumably
suitable for the relay logic within, but any idea what
actual voltages and amperages are?
After I dragged it home, I found there was not 1, not 2, not 3, but 4 MSCP
disk controllers installed in this BA213 cabinet. They are, KFQSA, viking
VIA/QTA, CQD223/M, USDC 1108. What a good day today! This is my maximum VAX
3800. My existing VAX 3900 is the minimum, by the way.

SDS/XDS and their Sigma 7 computer (and possibly ran on some of their
other Sigma series computers?) had a hardware diagnostic program
called SEX -- which was short for System EXerciser.

Hi,
A friend of mine needs to repair the power supply of a TRS-80 Model II.
I've found a schematic but without part numbers and values! He needs to
know the type of transistor Q1, there are no markings on the case of the
transistor. I've checked the power supply of my Model II, and there are no
markings, too. The Technical Reference Manual has all schematics for the
Model II, but the schematic for the power supply is useless without
component values. Might a BU208 for Q1 do the job?

How is the checking done? If it's purely by
name then it can easily be switched for
something much nastier without the user
finding out.
There used to be a fake "datatypes.library"
for Workbench 3 on the Amiga. Instead of
containing various datatypes functions/data
(say for JPEG's, GIF's and IFF's etc.) it was
a nasty virus.
Personally I prefer Workbench 2 and have
mine set up with my own custom icons and
mouse pointers :)
NB: For those that don't know, Workbench is
the Amiga version of Windows - or should that
be Windows is the PC version of Workbench :)
