It has a 68010 CPU, 4MB of RAM (As far as I can tell), and a multibus
interface that has the floppy/hard drive controller, RS-232 line
controller (with a dedicated 68010), a tape controller, and a controller
for a second bus that has an I/O modules of some sort stuck in it.
There's three more slots, so it's possible that additional Multibus cards
could be placed in it.
Right now (or after I get some sleep), I'm trying to determine the pinout
on the console ports so that I can connect something to the machine and
watch the console messages. I love (*cough* *cough*) the non-standard
DA15F and DE9F RS-232 ports on this thing.
The ST-506 interface drives are Hitachi DK511-5's, 41MB each. A bit
smaller than the 140MB drives I had with my Unisys U5000.
Pictures will come tomorrow, and be available at
