hap, I thought this adressing scheme should work on the real machine.

RAM gets adressed from EC00 to ECFF (in fact only bit 13 toggles RAM or ROM access, and RAM uses only 8 bits).

So if I place the 64-bytes table in RAM at 20C0 or EBC0 or ECC0 should result in the same thing.

Now if the DCO (Data counter) accesses the RAM at EC00, then decrements to EBFF, that should still access RAM at 2xFF or EBFF..

(The table HAS to be before RAM start, on the wrap-around.)

Am I wrong somewhere?
