The 8MB hard disk subsystem for the II/16/16B also works under XENIX and
can use the Quantum 2000 hard drives.  The Q2080 formats to 61MB under
XENIX 3.2.  The Quantum drives bolt in; line 5 of the data cable must
be pulled high (from the yellow insulated connector on the write protect
switch).  

>I have also heard mention of a cartridge tape subsystem. It shows

It was distributed by Radio Ranch, and had a 20MB cartridge.  The Bernouilli
Box was a better backup device (works also).

There were three - the 8" and two 5 1/4".  The two 5 1/4" 
controllers seem to behave the same.

I added double-sided Shugart 860's to a Model II with a 6000 CPU; could
not copy boot tracks, but everything else worked fine.

The 3-port cards don't work well with modems; the standard ports work fine
at 9600 driving a Telebit TB+.

It's a 386 now, but the XENIX 68K sources and binaries are still there.
Bob Bownes of beowulf also has some stuff.

"sir-alan" is moving on 9/15, new numbers not yet available (sigh...)

I also have 50 of the graphics cards (NOS).  Any interested people?
