Really? The very similar RS64, as well as the RS11,
both had a formatter device that field service could use to write the timing tracks if
they were lost. Or, for that matter, if the platter had to be replaced, since it arrived
from the factory totally blank.
Oh, sorry, meant the data was lost. I don't think it had the formatter
on the unit though.
Sure, a generalization of Dave Gesswein's MFM
emulator. I was just looking the other day how practical it would be for such a device to
do an RK05 emulation. The answer seems to be: quite practical.
The MFM emulator is an amazing bit of kit.
