I have a listing (green bar) of the PDP 8/e and /l music compiler. Is
this something of value to someone, or has this already been archived
someplace?
As far as I know, this may have been written here at the U of Minnesota.
I assume the Pascal Compiler that was written here is already available
someplace (it was once distributed by Decus). I have the original
floppies that were submitted to decus and returned by decus.

ACONIT recently acquired an Apple Lisa. It appears to be fully
functional except that the video signnal is shited right horizontally
about an inch or two. Doeas anyone know of an adjustment for this?

Originally, the SIPP was considered much more reliable than the SIMM. The
SIMM sockets were a new product at that time and failure rates were pretty
high, and it was easy to package a system more densely with SIPPs than with
SIMM's. It was easy to bend the pins on the SIPP's, though, and retailers
soon tired of having to hand-hold customers whose problems were simply bent
pins, as, once bent, the pins tended to bend again and again until they
were broken and repair was improbably if at all possible. Consequently,
SIMMs, though less reliable but easier to install, and less likely, in
either event, to sustain long-term damage took over the market.
Ultimately, socket problems were defeated by persistence, educating the
user public, and improved socketing technology.

I bought an S-100 card today at a hamfest for $1.00, now can someone tell me what it is ?
It's a "65k byte SupeRam 2" P65D2 Rev. C by PIICEON, Inc.
It has 64k of DRAM on it, 4 rows of 8 4116's, but the rest of the board does not look very "Ram-like", AND it has a 34-pin board edge connector at the top of the board. I realize that this suggests a 5" floppy drive interface, but a combined RAM and FDC card ????? Plus, the edge connector is VERY un-floppy like, normally a floppy connector would have half of the pins being ground, this clearly looks like it has active signals on almost all 34 lines.
Anyone who has information, it would be appreciated. I'd most like to get a manual and switch settings [there are FOUR dip switches on this thing], also the IC at 9B is missing and the board screening does not identify what should go there.
Regards,
Barry Watzman

It was exactly at T+73 seconds and Christa's mother is my next door neighbor
then and now. It was post max-Q transistion at main engine power up. Every
time I see a launch I get a knot at that time. FYI the speed attained at
that point is some 3600mph far from orbital velocity.
FYI: TLC had a special on space flight just that last week and that footage
was part of it. It's a reminder that I didn't need.

A magnification from one of my other posts:
Prior to doing a websearch, has anyone on The List any info about
the Sord Socius machine that I brought back from TRW?
It appears to be in the same evolutionary tree as the early NEC APC
series, ie; it uses soldered-in 8086 and 8087 (haven't looked for
multiples) and twin 8" drives vertically mounted to the right of a
12" color monitor in a large case with seperate keyboard.
Like the APC as well, is built like the proverbial masonry
defecatorium.
I also have the original (OS?) disk and another, that were in the
drives.

PS: I am just going out to unpack the haul from TRW, and I will
fire up the Nicolet scope and see if it works...
Zane H. Healy mentioned reading Mac disks in Windows:

There is a freeware utility called TransMac or something like that. It is
also possible to use Mac CDs and disks using the Executor Mac emulator.

Thanks... I'll have to recheck the manual, I guess I missed it. Now
I have to figure out what 'off' means... shorting pin 4 to what other
pin (shorted low or high).
I'm thinking of trying a KA630 as a coprocessor in a qbus pdp-11
system.
The KA650 manual mentions using the same board, but it says that only
the off-off configuration is supported. I wonder if the KA650 can
be a co-processor as well... But then, the KA650 doesn't have on-board
memory.

Whilst aware that I'm breaching netiquette by copying personal email, I
think in this situation that Chris won't mind, as he's trying to sell these
items. I can't afford the prices he's asking (I'm not saying they're BAD
prices, nor am I saying they're GOOD. I just can't afford 'em), and felt
that rather than waste the time of both of us by attempting to significantly
haggle-down, I'd let everyone have-at him.
Top part is his response to my letter in response to his newsgroup ad.

A guy said 10 days ago he would send $200 (plus shipping)
for the Unix docs, which I accepted, but I haven't seen the
check yet so maybe it will be available again.
The vic20 had a price.
I would like $250 for a stack of pdp11 hardware fisch.
$70 for a folding fisch reader.
How about $100 for H-11 doc 3-ring binders, and
$140 for the paper tape media software. This is unused,
partly sealed.
$80 each for a couple rk05 packs containing rsx11m, rt11, ?
What do you think?
Rebate if you convert my 9-track unix tar tapes to CD or TR-3
tape (windoz). Also, you can then keep the 9-tracks, contents
are probably interesting to you.

Hi
I'm a classic computer collector, very interested in your Heathkit items,
and also the RT-11 docs. I have just aquired a PDP 11/23 PLUS, and would
love any documentation for that, too. You don't list prices for these
items - if it helps, I offer a good home :)
Please let me know if these items are still available, and I'll try and make
a swift and easy transaction - if the price is right!
Cheers
