Mike, yes, I considered that approach too. No good if you want
RS-232 or I2C accessibility. However, for simple counting, PAL
is possible. However, you do need 16 output registers [for 64KB],
8/16 inputs for addressing, and 3-4 control lines.
As far as I can tell this would require 2 24-bit PALs in series,
or else go need to go a gate-array. Got any specific suggestions
along this line? PAL or gate-array?
