I just picked out of the garbage an IBM XT, it's in original condition
but with the addition of an AST 384K/Clock/Game board and 1200i Hayes
modem. She still boots and the 20 meg drive is pretty quiet!

I've seen that doc and I may actually have it (I have way too much
junk ;-).

S0 - comment section
S1 - 8 bit data
S2 - 16 bit?
S3 - 16 bit?
S4 - 32 bit?
S5 - 32 bit?
S9 - end of record

Oh, I see, I'm doing that with the HCSd right now, it doesn't make
sense to screw up the controller with half ad/l, an aborted one or
a wrong one.

I started as an EET but I learnt ;-) assembly and BASIC. The rest of the
high level languages I taught to myself. The S records and hex files are
a requirement for assembly langauge and EPROM burners (TI 2516 anyone).
