I am reminded of the IBM 1620... :-)
I've sometimes wondered how much the Cadet saved with the addition
and multiplication tables in memory. One still needed to implement
an incrementer, decrementer and doubler to handle routine addressing.
Could a 4-bit BCD adder have been that onerous?
While old architectures are interesting, sometimes you have to
wonder.
I think a serial ALU might be interesting for a variable word-length
machine. I'm not aware of any recent ones that have been built.
