Micro-TPDD SD Card Drive

TPDD2 emulation PCB for the Tandy Model 100/102/200. Highlights:

  • Uses Micro-SD card supports up to 16GB.
  • Rechargeable Adafruit LiPoly battery.
  • Supports the TS-DOS100/200 protocols.
  • Supports multiple boot options.
  • Uses USB power supply for recharge and running.
  • Can use a boot loader to update firmware from the SD-Card.

It should be capable of supporting the NEC machines but not tested.
