It's simple to convert the h9270 q18 (11/03) to q22. Just wire the additional
address lines. It took me about an hour to do mine.
Don't put an 11/03 in it after conversion. The added lines are not addresses on
the 03 CPU.

Since identify and read buffer return consistent data, timing would appear to
be ok. I would change the parameters used for read. iIRC you used chs =0/0/0.
Try chs=1/1/1

The current loop is actually "proper" .
There are 3 parts to current loop
1) transmitter (switch)
2) receiver (opto coupler in dec stuff)
3) current source
You will have problems if things don't match. An active transmitter has to
connect to a passive receiver.

Perhaps "card cage" is overstating what MITS did. Plastic guides screwed to a
PCB is far more accurate.

It not the rev 0 back panel for sure. I don't think it was a mistake either. If
they used the same layout as rev 0 the transformer would interfere with the

4-40 is the correct size. I would remove the jack screws on one side and
replace with sockets. If you use standoffs the screws May bottom out too soon.

This list seems to me to be populated with "build your own" types, so make your

There is a plastic bumper in the head/disk assembly that turns to goo.
When the head retracts it hits the bumper and gets stuck in the goo. The goo
will eventually win. The head will no longer load. I can't say For sure this is
your disk problem but it was a verry common Maxtor failure.

They still have them. They pulled the bin and put your name on it. It's about
100 (my guess) pieces at .15 each. I already did a lifetime buy myself.

There's a surplus place here in Orlando that has a bin full of dec style

The 74f parts may be too fast. Try adding damping resistors (10 to 30 ohms) in
series with the outputs to slow things down or just switch to 74ls

It had a rom but it wasn't a debug monitor. Disk boot of some sort.
I ported a monitor to the board using clues I found in the rom and a lot of
multimeter time figuring out where things went.
I'll look around and see if I can find it.
Thanks for the manual!

I'm trying to find docs for monolithic systems 8009 board.
multibus I, z80, RAM ROM 2 serial, FDC.
I see references to the board online but no actual docs.
I'm looking for information (schematic) for the on board interrupt logic
and bus interface.
I've figured out enough to get CP/M 2.2 running on

Take a look at the tu81 manual on bitsavers ek_tu81-tm_002_nov85.pdf
The appendix describes the m8739 unibus klesi. It's tmscp but it applies to
