Hey all -- Picked up an A&J System 100 drive -- this is an Exatron Stringy Floppy with a serial interface, meant to be used with the TRS-80 Model 100/102. I found what purports to be software for it (see here: http://www.club100.org/library/libups.html) but I haven't found any documentation. It would be interesting to know what the protocol is for talking to this thing. Anyone have any info? Thanks, Josh
