[*]Cassette seems to be working right already.
[*]MC6847
does implement (NTSC) artifacts. Why you say it is broken? Because it doesn't implement
PAL-M artifacts?
[*]Implementing Charlemagne/GEM-1000
depends on someone finding info on that obscure machine other than what's found in
Old-Computers.com.
[*]As for MC6845 (80-column card)... In this case we would have the machine generating two screens simultaneously. How is this to be handled in M.E.S.S.?
[*]I'd need a longer description of the other TODOs.
