Stuck in record! That one runied a few of the owners
tapes!
This won;t apply to the ZX81, but IIRC one of the Radio Shack recorders
that was supplied with TRS-80s (CTR80?) had a nasty design fault. If the
tape was stoped by the remote control socket _even in play mode_, it
would put a nasty little glitch onto the tape.
This caused particular problems with LII machines, becuase if they
detected a checksum error on loading, they'd stop the tape and thus ruin
the next block. That tape would never load again.
IIRC the mod (which Radio Shack did for free in the States, but Tandy in
the UK had no knowlege of) was to solder a 10uF capacitor across the
erase head connections (DC erase...) I did that and had no more problems
