Actually, our "new" one (which is apparently a pretty old design, and a used
box) is a bunch of PC hardware (386 motherboard, PS/2 style floppy, SCSI
hard drive, and some ISA cards, all in a custom cabinet about the size of a
large microwave oven). The phone tech showed me around inside it and told
me that the current models are built around a completely standard tower PC
chassis. As for the old box... I pulled out several large (~24" square)
cards full of Z-80's, PIOs, EPROMS, A/D & D/A converters, and piles of TTL
chips, six large 110VAC muffin fans, and several large diodes and a 63,000
ufd, 75v capacitor from the power supply. I kept the hard drive too,
although I'm not sure what I'm going to do with it. The rest went to the
metal scrappers.
