Also, Intersil had their own disk (floppy disk, that
is) operating system
for the Intercept I/II called IFDOS. I have a manual for IFDOS, but it
doesn't describe the floppy disk hardware for the Intercept. Was it a clone
of the RX01/RX8E? Have any copies of IFDOS media survived?
Charlie Lasner wrote it. I'm sure he must have a copy.
