I recently acquired a California Computer Systems model 2422 Floppy Disk Controller Rev B. (S-100) in what appears to be good condition but missing a 2716 EPROM presumably containing the onboard BIOS. Does anyone have this card and the capability of providing me with a copy of the PROM or at least a dump of it? I'd also love to get my hands on the docs, if available. Thank you, Erik
