RE: Wireless - switchless kernal mod

Hallo Nejat,

> After syncing, which is assumed, c64 program sends the chosen eprom bank for the selected kernal. Attiny receives this and switches the kernal.

I beg your pardon but isn't this a bit far sought? What about piggybacking a 6526 on top of an existing one? With a 74LS139 you can either demirror one of the existing 6526s, VIC and/or SID. (Or use IO1 or IO2 to address it but then you'll lose some functionality).

The biggest advantage of this solution IMHO: there is only one CPU you have to program for, thus only one source of possible trouble.


Met vriendelijke groet / With kind regards, Ruud Baltissen
