I'm looking at the memory dumps and comparing them
to the original file. It
appears for every 128 byte block, the order is backwards. I.e. if I look
at five 128 byte blocks on my PC they appear in the Z80's memory to be
as 5, 4, 3, 2 and 1. Not the 'correct' way.
I don't know if this is relevant, but records in CPM3.SYS are stored in
reverse order; the first record after the header is loaded at the highest
address, the next one 128 bytes below it, and so on.

Yes, that would appear to be the case. Thanks.
