Well, I was expecting to get a Heathkit H11 today, but instead got handed
something else.
1) A mint condition Heathkit H27 (dual 8" floppy drive for H11). Wonder if
it's usable on anything else?
2) An odd Xerox box with two pieces:
A) There's a keyboard labled G25-028409. It has these tilt-up legs of a
style I've never seen before (they turn and come down from the side like
landing gear). The cable coming off the keyboard (keyboard end is hardwired)
has a DB25 on it. There is also a DB15 port on the back of the keyboard with
little lock posts like you see on an AUI port. The keyboard is missing what
I assume to be the ESC key.
B) There's the main "unit" labled product Code U07, and U07-015414. This
white cube has a black 8" floppy drive in the front. On the back is a
hardwired cable that ends in a DB37, and also a DB37 port on the back. I get
the feeling this box is JUST a floppy drive, not a system. There is a floppy
disk in the drive labled "Xerox 8000, applications #5, Master Disk, part
130S01031, Rev OS4.2, code 2Q84, CS#0714". Whatever the heck that means!
Any one in the know about Xerox stuff like this care to expand on what I
have?
Thanks!

Perhaps the DB15 port is a mouse port? Tektronix 9200/4105 9201/4205
terminal keyboards have a mouse port on the back (with a little icon
of a mouse :-).

Could be, no icon on this one though. Given that it's a Xerox
of some age, I
was going to make a wild guess of lightpen or graphics tablet!

I suppose if you opened up the keyboard and called out some part
numbers that were attached to the DB15 we might be able to guess what
was connected there. If it was a tablet or mouse, its most likely
got a serial communications chip, while if it was a light pen I'd
expect some analog conditioning and a simple a/d conversion circuit.

The U07 box sounds like the external drive for a Xerox 820 computer
system. There should be room for two full height floppies or a single
floppy and an 8 inch hard drive. They have 37 pin connectors if I
remember correctly.
However the floppy disk in it may be for a Xerox Star 8010 since it is
labeled Xerox 8000. I would not be surprised to have one of the
external drive boxes hook up to an 8010 Star but I do not remember a
external drive connector.
The second keyboard could be a low profile Xerox 820 II keyboard. The
original keyboard was clunky and they made a low profile one that was
much nicer. Both of these had 25 pin D connectors.
Could be a Xerox Star keyboard (for the 6085 series also and the extra
connector would be for the mouse. The mouse port is a D9 though from
what I remember. I can't remember if it is a D25 connector for the
computer though. I have one in storage but can't get to it now.
My bet is they are two pieces to a Xerox 820 computer and you are
missing the 3rd piece, the computer which is built into the monitor.
The connectors match up for that. The Xerox 820 was a CPM Z80 system
designed around the Big Board Computer from what I understand. The
Xerox 820 was my third computer system. Upgradable to a 16 bit 8086
and could run early MS-Dos besides CPM86.

If the floppy drives stand so the slots are vertical, then this sounds like
an 820 external drive box (I use one to hold a couple of drives). The
drives that I've usually found inside are Shugart SA-800s--nothing special.
I've put some Siemens DS drives in mine. The cable coming out of the
thing contains orange and yellow wires in a black jacket and the 37-pin
male connector on the end is diecast zinc.
On the other hand, if your box is about 2 feet tall and has two 8" drives
with their slots oriented horizontally, you may well have a Xerox 8010
Star.

Just so we dont deluge the seller with everyone asking, I just sent him
a query about what else he may have. I have dealt with him a
couple of times and he is pretty nice. Just don't want to ebay
bomb him.
If he has anything, I'll send it on to Jay, unless someone else has
a burning desire to know.
This fellow is in Albuquerque, and is a relative of someone who
had a surplus business there, and is picking thru a pile of stuff with
what is listed. He has some s-100 stuff right now, including
a TEI frame (which I think he sold the cards out of and relisted),
and some other cromemco stuff. It varies from day to day.

Yup, that's what it is! Seems like I have an external drive box and no
computer to go with it. I haven't opened the cover of this box, but from
looking through the vents it would appear to have a 8" floppy and a hard
drive.
I've checked with the guy who gave it to me to see if he has the
display/computer to go with it. We'll see.

It makes a nice drive unit to use with an S-100 system. I owned
an IMSAI paired up with one of those. It had a pair of SA-851s
in it and was driven by a cromemco 16FDC.
