Consider the very old Packard Bell PB250--22 bit words, fewer than 400
transistors and 2500 diodes, 63 instructions.  Power consumption about 40
watts, exclusive of I/O:

The trick, of course, is to use bit-serial methods.  It seems to me that
one could greatly simplify construction of a homebrew machine that way.
We're not doing this for speed, right?
