Re: General 6809 card for 6502 machines

For atari 800 there is also a very small board with a 6809 that fit the 
6502 socket

+ a boot eprom for nitros9


I've tested this board on several 6502 machines.... no way to use it :(

on a SYM1 it seems to start but crashes immediately...

the SYM1 had a similar product named MOD69
