6309 microprocessor project.

Hello,

Working on the memory stuff and it's
a log hard slog., I need information to
speed things up.

Could someone explain how the newer coco3
rom cartridges worked.  The ones that accessed
more then 32K ROM?  Where the ones that did
use more then 32K using the same memory map
and switching methods?  How did these rom
cartridges switch memory in&out?  What was
the most ROM, a cartridge ever used?

Also I'd like to learn more about the Multi-Pak
and how it switched between rom cartridges?

Any help appreciated; thanks.

John Collyer
