Since there seems to be much interest in Turbo MSX (and not only in
this mailing list but in Russian FIDO MSX conference, I am going
to recover the notes for my 10.5 MHz design and put them out
on the Novatec Projects page - with other projects as well.
MSX bus in most computers *DO* support frequencies up to
14 MHz. If you change memories for faster ones, that may
become 20.
