Re: 6569 luminances

OK, you've convinced me!

Mind you, I wasn't just thinking of a single position switch; a 512kb
E(E)PROM or FRAM would give you 8 different 8kB ROMs.

And I think a glued switch is definitely much geekier ;-)

But..

- the number of ROM images is virtually unlimited with today's capacities
- if you have more than two, then one switch is not enough
- images could be easily managed, (updated, added, replaced, deleted,..)
- any combination of all ROMs could be used (potentially including standard
cart ROM software)
- it would be _much_ more elegant than a glued switch (and geeky ;-)

It indeed does something similar (for KERNAL only), but:

- it is a cartridge that has to go into EXPANSION port (mine is long
overloaded, while I would gladly replace power hungry ROMs)
- it does the trick only for KERNAL
- it is only for C64, whereas what I suggest would be adaptable for other
6502 systems with relatively low effort
