All:
I was contacted about an Apple //e system available in Montreal. The
system consists of the //e, a DuoDisk drive, monitor and manuals but no
software. If anyone?s interested, contact me off-list and I?ll give you the
person?s email address.
Thanks.

I have a 68000 MECB clone board and a large number (70+) seven segments
that I would like to do a project with - I'm open to interesting an
novel suggestions!
My first thought was to create a 'snapshot' board with a set of eight
displays giving the value of each register at a breakpoint in the 68000
code to aid in debugging. However, I'd quite like to do something with
remote sensing such as a weather station or the like.
I remember such displays being used for telescope controllers, alas, I
have no telescope.
Any suggestions gratefully received!
Mark.

With the recent discussions of the PDP-11/20, I've been thinking of
what all I'll need to gather to restore mine. It's been a long time
since I pulled things from the pile, but I'm pretty sure that before
it was pitched, the fans and PSUs were harvested.
I've found pictures on the 'net of the fans - looking at the wiring,
they appear to me to be pretty standard 110VAC boxer fans. ISTR
hearing that the fans in the 11/40 or 11/45 are bizarre, but I'm
expecting that the fans in the 11/20 are ordinary. This leaves the
PSUs. If I were going to go with MOS memory, I wouldn't worry about
what to use - the Unibus itself only needs to provide +5V, and +/-15V.
Because the 11/20 routinely held core, it's expecting +8V (unreg)
plus -22V on top of the usual voltages.
Since the "easiest" solution is to get the original equipment
reattached, I'm curious how much an H720 might fetch these days. If
it's too much, I can always come up with some other way to provide
power to run core (or skip the core and use MOS).
My question for those that have tried recently, is it feasible to go
searching for 1-3 H720 PSUs, or are they old enough that the chances
of running across them are slim enough to make building a functional
replacement a preferable go (preferable from the standpoint of ever
being able to finish).
Thanks,

My newest pdp8 has an OEM Dataram DR118A memory module as well as some DEC
core. Does anyone have a data sheet for this or know what size it is and how
to check/set the field addresses for it?
Thanks - Bob
I really meant SGI 4D/310 VGX. It turns out the machines I picked up
at gummint auction from NASA Langley were better than I thought!
Thanks to some help form fellow local cctalk'er Tim Riker, I was
able to move these from a neighbouring business to the warehouse.
For some stupid reason Estes freight delivered them there instead of
calling me and leaving me a voicemail message. After they delivered
them to the wrong place they never bothered to call me and tell me
about it. Grrr.
Anyway, these look like nice systems. They are in good cosmetic shape
too. Now I need to find some power cords, disk drives and IRIX media
for them and get them up and running again.

As I've mentioned in the past, we had a family friend when I was
growing up that had a Challenger III. I got to go over a few times
and play on it. At one point, I was helping him recode a BASIC
program in 6502 assembler, but my skills at 13 weren't quite up to the
task with his tools (I did OK at home poking out simple stuff).
I've never seen another one, though I'm sure they sold more than one.
In fact, OSI was two hours from my house, and I've only ever seen that
one C3P and a couple of "Superboard"s in the wild.
If I ever saw any OSI stuff at a hamfest, I would have bought it, but,
alas, no. I'm not sure I "need" to own a C3P, but it would be great
to play on one for a day or two. Anyone one the list have one they
could hook up to a serial line that's net-accessible?

Bit of an odd one this, rescued along with a Seiko graphics tablet (but
no puck) and a 15" rather nice Sony monitor that needs 110V.
It seems to have a 286 and a 68000 (or similar) on several boards inside
a case about the size of a biggish PC tower, with a 3.5" half-height
hard disk and floppy drive. Seems to be Japanese and for the Japanese
market, judging by the labelling.
No idea what it does, no idea what it is, never even fired it up, it was
just a bit too good to skip.
If anyone wants it, pick it up in Glasgow - mail me offlist for details.

Item 160329193774.
Sure, it doesn't work. And it's missing most of the parts. But it's an
Old computer, and the bidding starts at under $4000! Sounds like a great
deal to me!

I have a photocopy of some pages from a book of BASIC computer games from the 1980's.
The copies I have are of the games "Freebish!" "Crops" and "There's Gold in Them Thar Skyscrapers"
1) can anyone ID this book they came from?
2) Does anyone know of an updated version (java, etc) out there?
