The 6x0 and 7x0 have the same video logic, including the 6845 (or 6545,
remember). Simply replacing the charrom and modifying the hardware
(jumper I think) should possibly make it run in the other mode.
VICE has a nuber of switches besides the pre-defined (i.e. factory 6x0
7x0) modes.

The 5x0 has to some extent the same hardware, but with the 6845 replaced
a VIC II, and a different memory layout due to this.


P.S.: Normally I do not write mails from my web mail provider, so I
forget that cbm-hackers does not accept them. In fact I'm fine with the
address, thanks.
