I like the odd
angle of the chip peeking thru the hole at the bottom
of the photo which is on the floppy drive.
I noticed that. :)
I took the SCSI interface board off the floppy drive and took two more
pictures.
there is a ram just above it (U3) (28 pins)
U1 is probably the scsi controller
U4 is probably a prom (28 pins)
guessing U5 is a microcontroller (40 pins)
