- Hmmm... Someplace I think that I have the schematics for the
- Kansas City Standard Casette interface. I think that that was
- the interface that most micros of the late 70s used. The
- actual format in which the programs were stored varied from
- machine to machine. Some machines stored the actual keystrokes
- so that loading a tape was just like typing it in at 300 characters
- per second. Others stored interpreter codes (assuming you're
- loading a BASIC program). Some, like the TRS-80 I think, could
- also directly load hex from tape.
