Aside from the cheap SBCs like the Pi0 and CHIP there are a number of dedicated RS-232 or parallel to USB adapters that are _almost_ ready to go, just needing a level shifter/clamp and some simple software.

I was wondering if you could use any USB Flash drive to save files. Maybe have some software written for it so the Model 100 would understand it. I heard of the NADSBox and Raspberry Pi. But the NADSBox is expensive and I am not sure if it is available anymore. As for Raspberri Pi. It is $35 dollars. I have even seen one for $15. Even a CHEAP one for $5. But I am not a very technical person or software programmer or hardware engineer. I am just a basic user and owner of a TRS 80 Model 100. Any suggestions or opinions that I can get. Duane A.
