[Wear-Hard] Twiddler-1 conversion to USB?

[Harmon Seaver]

   I just dug out my Twiddler, haven't played with it for years. It's
the old style, not a #2, and has the old PC din connectors, although I
added PS2 adapters on those. Anyway, I'm wondering if anyone has rewired
theirs for USB?
   Since the DIN connector is just for power, and the actual key codes
go through the serial connector it seems doable, maybe even just with
PS2 to USB adapters and a serial to USB adapter, but that also would be
pretty clutzy. Much better to totally rewire the thing, if I had a
schematic for doing it????
