Hello, all:
"Massimo from Italy" has been sending me more scans and stuff related to
the SYM1. So much so, that I may put up a "SYM1 page" on Highgate. He's now
working on scanning the SYM Physis, a newsletter for SYM users (1979-1982).
If anyone has anything they'd like to post, let me know off list. Also, I'm
looking for a small Web-sized picture of the SYM for the page (I don't have
a SYM to photograph).
Thanks.

An 11/23 would run RSX-11 just not the I&D kernal, same for Ultrix
depending on version.

It was happening when the processors were NEW. Seems it made a very
compact fairly fast system if the DEC box was not used. However early on
getting the bare CPU was difficult so people bout 11/53s, snatched the
cpu
and resold them with commonly available 11/23s (as Micropdp-11s)

Yep, like my 11T03 that has a BA11N and 11/73 cpu or maybe my
microvax-ii
that was downgraded to a Micropdp-11. ;)

To any CP/M 2.2 users with 8-inch SSSD floppy disks...
I'm restoring an Imsai 8080, and at this point my hardware is working
very
well, but I need some assistance with the software.
If any list member can help, I'm willing to trade classic hardware such
as an HP
9830A desktop programmable (in basic!) calculator, a Symbolics 3645 Lisp
Machine
(with 2 monitors, and full doc set), a Solid State Music S-100 bus music
synthisizer, DEC goodies, etc...
Lets make a deal....without eBay.....
All the hardware for trade is located in centeral MA, not too far from
the site
for VCF East!
Who ever gets this deal, and helps get this Imsai up to the A:> prompt
WILL be
made happy.
(and share in the satisfaction of saving this particular Imsai from the
dust bin
of history)
My problem is this:
I need a bootable 8-inch, SSSD CP/M 2.2 disk made with a BIOS for my
hardware...
I do have full documentation for all the hardware installed in my
system.
I have an Imsai 8080 with 40K of RAM, a Tarbell 1101-D floppy controller
with 2
SA-800
drives, and a Solid State Music IO-4 board. There are some old CP/M 1.3
disks
that came
with the system, and they ~appear~ to boot, but I get no console I/O.
Most of the
disks
claim to be for memory configurations larger than I currently have.
I can disable the Tarbell boot code and enter small programs by hand,
and I've
verifed that
the SSM IO-4 boards serial port is fully operational. Attempting to
boot a 24K
CP/M 1.3
disk ~looks~ like its working, the head loads and unloads several times,
data gets
loaded
into memory by the boot loader code from the floppy, but no console I/O.
Who knows what hardware config this disk expects, it appears to be a
very early
CP/M
install for this Imsai, and its clearly been expanded several times
since this
disk was cut.
I'd also LOVE to upgrade the many 2102 based Ram boards with any
non-2102 based
SRAM
board. I do have 22 slots, but 4K and 8K boards just take up too much
room.
So, is anyone out there with 8-inch CM/M 2.2, and who is just dying for
a
Symbolics 3645?
Just 'gottahave' an HP9830A (all key caps, unbroken plastic, etc) LED
dot matrix
calculator?
(check one out on the HP calculator museum site, clearly collectable...)
Drop me a line off the list, and lets make a deal!

Still have 2 left of the ones listed below if anyone's interested:
--------------------------
I have some AC adapters I bought in a lot, I gave $1 each for them and
pulled what I need from them. Input is 120VAC 60hz 800ma and output on a
standard round/tubular "coax" connector is 16VAC, 4A. Fused with a 5A/250V
fuse built in and changeable if blown. They're bricks with about 3 ft of
wire to the 2 prong AC plug and about 3 ft to the coax adapter. Brick
measures about 3" wide, 3.5" deep and 2.5" high. Made by Eltron with the
part number 808061-001.
I have 4 I need to get rid of at $1.00 each plus applicable postage. They
weigh 3 lbs each. Someone can have them all or just 1, 2, etc. I'm in
central KY in zip 42726 in the event someone wishes to calc shipping.

The Apollo Domain DN10000 used up to (was it 8?) 88k cpu's... it
was modular in some way, so that a system could be expanded.
I hope to add a DN10000 to the collection, eventually...

There's a couple of other uses for it:
1) It can run HP-Word from an HP-3000.
2) With a floppy, it can be used to boot an HP-3000 Series 70.
3) With a touchscreen, its a great terminal for a dumb blonde.

It wasn't a bad little computer for its time. But by making it
so incompatible HP missed the boat, as usual.

A friend is cleaning out some storage space and has a couple of boxes of
Kaypro related items available for pickup or shipping only. Each box is
approximately 12x12x16". One contains 5.25" DSDD diskettes containing
an accumulation of programs from his BBS days. The second is of manuals
and magazines - Profile, etc. Sorry, I can't be more specific, but if
you are interested contact Milton Blackstone at 858-459-8255.
He would like to see them go this month.
Thanks.

I am cleaning out my closets and have the following available. I am mostly
interested in trades for older CPUs, coprocessors etc. All the board should
be in good working order, but no guarantees. Shipping is on your nickel.
