All make the assumption that you must make 8 bit/16bit
or, in your case, 20 bit. One can make a 1 bit alu that
can have data width controlled by instruction. It may
not be fast at math but much processor time is consumed
just looking at true/false. If your model doesn't require
passing data through the alu for mem/mem and mem/io moves,
a single bitter makes sense.
( My Nicolet is a 20 bit machine. )
Darn! All the good computer names are taken. :)
Do you have any more information?

Some day I would like to see a DECIMAL computer in
TLL or FPGA like the early decimal machines.
