Phil - Search for Push-In Rivets (plastic, nylon, etc.). Two of the largest mfg. of plastic Push Rivets are just east (Richco, River Forest, IL) and north (Fastex, Des Plaines, IL) of me. Both have been acquired by larger conglomerates. — Richco (River Forest) was bought by Essentra Components

All IBM XT era drives. I have, have had or have given away at least one of these before. Find a good working ibm xt and a genetic controller with a manual and a copy of Spinrite software and test 'em. These are all stiction prone and bad cap vulnerable. Bill On Sun, Dec 6, 2020, 9:25 PM Chris Z

I'd suspect that at least a few of these were from PERQ systems, given their provenance.  Vertex V150s and Miniscribes were commonly used in the T2 models.  As another listmember mentioned, Dave Gesswein's MFM emulator will image these (and can decode PERQ hard drive formats.) Probably. I didn

Yeah, the later models used 5.25" media; the rare PERQ 2 used 8" Micropolis drives, and the PERQ 1/1A used 14" Shugart SA-4000 drives. Ok, is there a picture of a Micropolis 8 inch anywhere? If so I can watch for it. The other oddball is the Miniframe, that box had no drives any idea what they
