- It hadn't even occurred to me to just plug in a ZX81 tape and load it in
- with the ZX81's tape code. What a great idea!
-
- I've got a commercial program for the TS2068 (it hasn't been sold for
- several years) that reads in ZX81 programs and does token conversion so
- that you can run the BASIC program on the 2068. They give instructions
- for inserting a capacitor and resistor in the tape lead (some kind of
- filter). I tried to load ZX81 programs without it, but couldn't. Maybe
- there's a subtle difference between the Spectrum and TS2068 tape
- interface? I've never had trouble loading commercial Spectrum software
- by tape.
