i looked again, it's not a 2000, it's an A1200
(i used to have the 500 when the 2000 was "the hot one to have", so i guess i just got mixed up)
it's got a Seagate ST9096A 85.3 MB
it's got the 3.0 ROM chips in it
a motorola processor on an expansion board with an additonal memory slot, a realtime clock, a BIOS battery and a copyright notice that reads: 1993, Microbiotics, Inc, Made in USA
next to the processor itself, written on the board it says MC68881/2.
