Fully agreed. I'm trying to understand the tape routines of one of my
synthesizers and it's just giving me a headache. Counters triggering each
other or error routines...
But since that was a common technique back in the 80s there must be some
information around. Has somebody taken a look into the
(so-called) documented ROM listings of the Sinclair machines?
