This is a WD product and has a 21mb model 93028-5-20-1989. its 40 pin IO is IDE and the board has eprom and nus interface parts only. It carries a board date of 1988 and all the chips on the board have '88 or earlier date codes. It is ISA-8 (small card) in a frame that carries the card and the drive with is the 1.5" thick 3.5" format. CHS written on it from my system days using it has c=782,h=2,s=27. FYI its slower than sludge as its a stepper drive for the heads.
I find odd stuff when I go in the closet where I store things.it was under 4 Compaq 1.05 GB SCSI-2 drives.- Allison
