Bob,
I'm not far away, Maybe I can help. FYI I have NO data on the tarbell
controller but if the disk is standard SSSD I can help.
No interest in the HP or symbolics though, too far off my collection.

Subject: Will trade classic HW for CP/M 2.2 help!
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!
