I'm looking for information on how I can add a couple RAM chips 8K x 64, and
a 28C256 EPROM with the
68HC11E1 uP. I want to know how to map out the memory locations using the
74HC138 3 to 8 line decoder.
I've seen the schematic for the old EVB from Motorola which is not available
anymore.
Can anyone explain how to "ADD" and then map out memory locations with the
68HC11E1 with the hardware I described
above? (Logic levels for ModA, and ModB equal 1)
Thanks
