Subject: Strange machine

Recently recived a slighty strange machine, and wanted to get some
input on it. Its not a bad machine, but a little odd, and in being
odd, may be hard to do certian things...

First off, its called a DE-100 Disk Emulator, from Design Analysis
Associates. Theres two ports on the back: console, and remote. Both
are RS-232C. The console is at 9600 right now, and remote is 2400.

On the front is where the bizzare stuff comes into play. First, its
got a 700k DSDD 3.5" disk. the front panel has a bunch of ports:

a floppy connector (standard 5.25" not 8"), and a whole array of
LEDs that match each line on a floppy connector (track 00, select,
etc)
 
Then theres five other ports for hard drives (5.25"): one address
buss, and four data buss connectors, and the same LED array.

Inside is a card cage, mounted on a hinge, with about 10 cards.
The CPU is a Z80A (or it may be an H). 

It runs CP/M 2.2, comes up with 62k RAM, and runs ZCPR2 and ZCPR
3.4 just fine, it even has a version of MDM and its associated
overlay. It also as a RAM drive at C: with about 189k. Also included 
is the disk emulator software, which of course I have no idea how
to use! One thing, somewhere along the line I ran a program
called MEMTEST, which does some insane diags (takes 41 minutes
to complete!) It states 'STD-buss 256k'. I seem to remember 
STD-buss from somewhere, but cant place it..

Anyone? The machine was basiclly free (part of a trade deal. But
since I dont have a personal CP/M machine, its the best I got. A 
Xerox 820-II is running a BBS, so I cant use that...)
