TU-58 questions

Hi Ethan,

I built some magic cables and plug the bare drive & board into a
PC to dump the tapes. If you are interested, I'll dig up the
source to the DOS program I used...

I also have the TU58 tech manual, so I can post the jumpers if
needed. I'd do it now, but Nascar is starting and I need to pour
myself a coke :)
