Curt J. Sampson 08996975e0 Bus: Address decode mods from third party developer appleii6502 2020-05-24 20:37:46 +09:00
Curt J. Sampson d9f2d1bc8b Bus: Add comparision with RC2014 bus 
The backplanes (though not the cards) are actually fairly compatible,
so we include this information to give guidance on using a backplane
from one system with the other.

This may also provide helpful insight for RC6502 board designers.
