lo-tech TRS-80 IDE Adapter (rev.2)

The Lo-tech TRS-80 IDE Adapter is an external IDE storage adapter for Tandy TRS-80 model 3/4/4P PCs, enabling connection of standard IDE drives (and CompactFlash cards, with an adapter). Based entirely on 7400 series logic and through-hole components, the design offers a low-cost, self-assembly storage option for these machines.

The design has experimental (i.e. untested) compatibility with the TRS-80 Model 1 and, via the Hans-01 PCB, can be used with the Model II with the replacement of one IC.

These boards can be purchased online via the TexElec Store.
