They're both actual Tandon drives, dated from 1981.

I did this to one drive, and got it working, but the other is beyond
repair. A penny was once dropped into the computer by my friends 4 yr. old
cousin. The penny landed on top of the top drive PCB, shorting some stuff
and fusing the penny to a few components. I need at least one drive.

I may just try making my own cable out of an old piece of ribbon cable,
some clear plastic, and some Super Glue. That's basically what the
original one was, anyway.
