Over the weekend I dissected two commercial alarm panels people had saved
for me. While I was grateful for the thought, I didn't give my donors much
credit for being discriminating. Boy was I wrong.
When I opened the first panel, the board inside had a 6805 sitting smack in
the middle of it. It also yielded a 2716, a 2764, a 6821, and a pair of
6116 static RAMs, along with numerous other Motorola-branded support chips
and passives. I thought that was a pretty cool find, especially considering
my short-sighted view of its potential.
Panel #2, however, seems to have been the real gem. The large board within
didn't look that interesting, just the usual myriad passives, and the panel
was clearly very old (looked 20 years or more). It had a daughter board
about six inches square and fully enclosed in shielding, hiding its
contents. I removed the board, stripped it of its shielding, and found...
an RCA CDP1806, two 1852s, an RCA-branded 6116, and three other support
chips. The label on the 27128 EPROM on the board says "(C) 1984".
Simple stuff, but I was jazzed. Classic computers are
everywhere... --Patrick
Dear List,
What is the concensus on disposal of 286 and 386sx
hardware -- should they be consigned to the bin, or
are there any folks out there collecting them? (or
needing spares?).
One is a Schneider 286 Tower PC (10Mhz), and the other
is a Philips P3345 (16Mhz).
Personally, I do not view either as being particularly
noteworth (other than, perhaps, for sentimental
reasons) .. but seems such a shame to turn them into
landfill :-)
Best regards,
Roger

Hi,
I was looking at a vendor site and it looks like they are offering an
DEC 11/750 for $158.76. It's not quite clear, but since I don't have
room for one I cannot simply order it. If you want it for the price,
you can go on their web site to just order it and then call and ask
them that you want to pick it up, that way you can find out what
really they offer here and if it's not a real 11/750 system you can
jump off (but if it is, you have a pretty good price.)
regards,
-Gunther
New toys:
Apple II Mouse Interface (I have one somewhere in a box that I haven't
seen in years, so it was faster to buy another one ;-)
Apple II Network Workstation Card (2). I've done some Googling, and it
appears that I may not be able to use these in any Apple II I currently
have (they seem to require an enhanced IIe). Ultimately, I'd like to
lay hands on the Mac server software (3.x?) that will let me boot an
Apple II over Localtalk and treat the Mac as a remote disk drive.

ps. Still no luck on the Teletype Model 32 documentation. I started
going through the model 33 stuff. It's close BUT still not it. I think
as I work on this project I'm going to take pictures and document what
I do. I'll post it on my web site to help other Model 32 users.

Well today's been interesting.
There was snow on the ground this morning.
At a Lotusshpere today I won a pair of tickets to the hockey game this Friday.
And I just returned with an Arix 800, (quite large, hard drives have been
pulled but the tape drive and cards are there), a Wyse 60 terminal, a box of
unisys docs for u5000, a tape with PDN-5000, and windows 286 in the plastic
wrap, a scanner new in box, and two clones that are missing the drives but
still have the cpu's and ram.
I was also offered a very old telephone switchboard this past weekend.

You might try dropping these folks a line, and see if they still have any.

It's been a few years since I got one from them, but I only payed $30 for
one, IIRC.

When I got several Kaypro II etc. machines several years ago at the
thrift store, I also found a bunch of related floppy disks. Several of
them are apparently copies of disks from Micro Cornucopia at Bend,
Oregon (a mid 80s magazine?). They appear to have lots of useful
software, I think public domain...assemblers, utilities, etc.
I finally got round to getting 22disk running on an XT, and I've been
reading these old floppies, and copying the contents to the hard drive
on my main computer. No read errors yet, and I've done a dozen!
amazing....
Is there any interest in this stuff, such as on a CP/M archive server
somewhere? I should be able to zip it up and email or ftp it somewhere.
I don't have room on my home page (url below).
Here's a sample of what's in them, from part of the .doc file for one of
the disks:

CROWECPM.COM
CROWECPM.DOC
CROWECPM.Z80
This program is for all of you that wanted a Z80 assembler without spending
hundreds of dollars for it. We modified the CROWE assembler so that it
would work under any CP/M system. CROWECPM accepts standard Zilog mnemonics
and creates a .HEX and .PRN files. The .HEX file is in Intel format and can
be used to create a .COM file with the CP/M LOAD.COM. A symbol table is
listed at the end of the .PRN file. It is a good assembler and the source
code is included if any one would like to make it even better.
See CROWECPM.DOC for information on using the CROWECPM assembler.
-----------------------------------------------------------------------------
LASM.COM
LASM.DOC
This is another assembler. It is a rewrite of the standard CP/M ASM
assembler. The difference is that this version can link assembly language
programs together at assembly time. This version also runs faster the
ASM.COM. This could be a the begininning of a linker for our Small C+.
See LASM.DOC for details.
=======================================================
Neat stuff, obviously.

You know, I really should put my copy up on eBay, the shrinkwrap and box
aren't as perfect as that, but I could sure use the cash for some software
upgrades for my Mac!
