Wow those were the days:
Hard Drive IDE Disk ST-157A Seagate 902020-004 85746196
Interface: IDE
Drive Capacity: 40 MB
MPN: ST157A
Rotation Speed: 3600 RPM
Model: Legacy
Heck the on board memory buffers have more capacity now. 64 megs seems average.
Havent seen an old drive like this posted on Craiglist in a while. Just wanted to share for nostalgia's sake.
