Hi John,
The Source is done - I burned some midnight oil last night on the IIgs and
sent
it back as a textfile. Now looking at it, I can plainly see many places
where I
can improve the routines for speed. Why LDY, INY, CPY, BNE when I could
LDY, DEY and BNE for most of the routines don't break any $FF barriers!
Also my page select code is SLOPPY with a capital SLOPPY. It could be
entirely rewritten to ADC $04 to the page offset desired, then check if it's
past the last page ($4C00) and needs to wrap back around.
Anyhow, here you go:

Enjoy!
Later,
Craig
