So last night I found out that HP sometimes sucked at documentation. Had to look through the service manual for the HP-9895A floppy drive unit to get information on the command set used with the HP-82901 and similar units, so I can make an emulator to work as a boot device for my HP-125. The command set's successor, CS/80, got its own manual so I'm a bit frustrated the original command set doesn't.


Either way, found the documentation I needed. Probably going to make a device to act as either an 82901 emulator, or a general storage device for my project computers. Using an SD card as the storage media, a switch to control mode, and a thumbwheel to select between 8 'disks' on the SD card while the 'standard' mode will use the rest of the SD card for use with my project computers.
