Hi Joe
Al Kossow has schematics for this board. I don't recall
which ones were which but one of boards ( with a little bit
of modifications ) could have CP/M-8000 brought up on it.
If you want to try this with one of your intel floppy
cards, I'd try to help you. I can compile the code on my
Olivetti M20. It is mostly just getting the BIOS done
and a little fiddle faddle with the addressing.

So long as it's FM/MFM it's pretty much the same for any controller --
otherwise disks wouldn't be so interchangable :-)
If you want an external floppy, why go to a lot of effort when all you
need is one of the old cards that had an external connector? It's
normally a 37-pin D-connector, with a few pins used to supply the
power. Of course they're ISA cards, so you'd need a machine with ISA
slots, but your reference to "ISA bus hang-ups" implies you have that.
You also need to be able to set the card to be the second floppy
controller (but most of the ones with external connectors have that
capability) or disable the on-board floppy controller (if there is one
-- but most older boards can do that too).

I just posted some pictures of the AMC/AMD Z-8000 Multibus chassis and
cards that I found last week at <http://www.classiccmp.org/hp/amc/>. The
chassis and CPU card are marked Advanced Micro Computer. AMC was a short
lived division of Advanced Micro Devices (AMD). The CPU card is marked
96/4116 Monoboard. The other two cards are wire wrapped. Most of the ICs on
them are SSI ICs but the one card has a bunch of Singnetics PLS 105N
Programmable Logic Sequencers.

Hi all,
Thanks for contacting me privately. There were two people that were off by the same amount so I will contact them seperately. The number was 53 for those who were interested. I had one guess of 48 and another of 58.
Thank you to everyone that responded and I am sure that these boards will go to a good home.

The only thing I could contribute is that there is a Software package
that emulates the HP64000
In compiling code, free to download. You probably already know this.
Is there another HP64000 available?
I could possibly get copies of manuals and SW from a place I used to
work at.

This list supposedly allows for Off-Topic posts. cc-tech is the list you
want.
I stumbled across your question whilst looking for something else. I don't
know much but.......I can tell you that in a Linear Accelerator (used for
treating cancer with high energy photons (X-rays) or electrons, there is
sometimes a system called Portal Vision which allows digital images of the
treatment site to be taken during treatment. For Varian machines, the
cassette holding the image capture device is on a retractable "arm"
controlled by a control system on a GESPAC G-64/96 bus. CPU is MC68HC000 and
the operating system is OS-9. You may have an R arm controller or more
likely some other OS-9 based system.

I need as much information as possible - but at least the DIP switch
settings - for a Cromemco 64KZ II memory board. Note, this is the 64KZ II,
which is a different board from the Cromemco 64KZ (No "II"). If someone has
a manual that they will loan me, I will scan it into a PDF file and return
it.
Thanks,
