You want an ALU? That is just an logic circuit (no memory) with a bunch
of inputs and a bunch of outputs. You have a lot of EPROMs around? An
EPROM is a circuit with a lot of inputs and a bunch of outputs, the
logic that appears to be inbetween is programmable. So IMHO you have a
lot of potential ALU's, they just need programming!
