Do you still have an image of the ROM data?
It can be found with Google. Search for the part number of the ROM,
23-089E2.
I would study it a little, as producing a formatter
(also using TU58
mechanics but different electronic) would be very interesting...
I think it would be easier to use the same electronics. The only issue
is that I think a small modification might be necessary to produce the
"mark" waveforms used at BOT, EOT, and in IRGs. If that does prove to
be necessary, it should be a very minor addition, and shouldn't affect
normal operation of the drive.
