Oops... wrong key...
I have an SC21 on the way (as I mentioned elsewhere). I have some 10" and
14" SMD drives I could steal from an SI9900, but I'd like to find some
lower-power drives to play with - I'm thinking 2BSD on a Unibus PDP-11,
so anything from a couple-hundred megs and up would be great. Are
there any non-SMD-E drives in the the 5.25" size? Would anyone know
where I could pick up a couple? I remember there were SMD drives up
to 600MB in that size, but I don't have part numbers and I don't remember
the exact interface type (I just remember the ads on Usenet where the
seller was warning people that these 600MB-for-$600 drives would *not*
work on your PC).
Thanks for any help locating some smallish SMD hardware,

I didn't know that any of hte 75's or 90's had the FDIV bug... learn
something new everyday

Got lucky today and picked the following items:
BYTEK Multitrk-2000 Universal EPROM programmer with 3.5 FD in the side with
the software diskette in it.
BYTEK 135 Multiprogrammer
BYTEK MPM-1
Four Microvision games in the boxes with manuals; Connect Four, Mindbuster,
Star Trek - Phaser Strike, and Bowling
NEC Pinwriter P3300
For those looking for up-to-date VMS media for you Classic (or other) Alpha's,
I just noticed that Montgar has the OpenVMS Alpha 3.0 kits available.
Finally!

A friend of mine at work got the 11/750 recently offered for free in
Pittsburg. I don't yet know how it's loaded except for the L0022
mem controller and 14MB of RAM. My friend would _like_ to get a CI750
for it, since he already has an HSJ40 at home. Barring that, he's
considering the $$$ for a Unibus SCSI controller.
Besides the actual L0009 card, I'm reading that there appears to be
an external enclosure to house part of the CI750. My 750s were always
a local-disk affairs (UDA50/SI9900/etc). I have no experience with
CI hardware and don't know what advice to give him. Can anyone here
describe what you need to pull this all together (he already has
an SC008 and cables).
I'll try to get him on the list... he currently has about a dozen
Alpha Servers and is in the process of working backward in time
in the DEC world.

I have this dual-height Qbus card that I was told was a SCSI card
(got it from a former boss). It has a 50-pin connector and gives
the appearance of being a SCSI card, but I can't find any docs on
it online. The logo reminds me of Systems Industries', and the
model number appears to be "CS-1". I checked with Al's site and
there's no SI docs there at all. There's a good chance that this
is a TMSCP device, not an MSCP device, but I don't know that for
sure.
Is this board familar to anyone?

Here is the latest information on the Monrobot XI computers that have
become available in Virginia. I'm afraid that while I am quite
interested in these, I will probably be unable to acquire one. It seems
they are interested in selling them rather than giving them away to
good homes. Any reasonable sale price in addition to the considerable
cost of shipping a 500 pound machine will probably put them out of my
price range. I'm hoping that some public computer collection will
acquire at least one of these and make it available for viewing. I
would be happy to help in the rescue if anyone here decides to buy one.
I would even consider contributing to the purchase and transportation
of a machine if it ends up in a publicly accessible museum or
collection.

I have a bunch of older National Instrument data acquisition cards
available. Best offer or trade for older CPU processors.
NB-GPIB, macintosh Nubus GPIB card
AT-AO-6/10, ISA bus analog output card
PC-TIO-10, ISA bus timer/counter card.
I have manuals, cables, and signal breakouts for some of these.
thanks Norm
