I've been tinkering with a Tandy 102 lately. Recently picked up a TPDD2
drive with no cable. I have to construct one so I can use it, and then I
don't have the Utility disk, so I'm not sure how useful it will be.

The one I got needed a new battery backup battery, and I had to repair a
trace. The system would work, but the memory wouldn't retain contents. The
AA batteries leaked on the power supply trace and etched it away in a small
section, enough to sever the NiCad connection to the RAM, but leave the AA
to power the RAM once turned on.
