I don't expect many people will copy that. A FPGA 8080 runs darn fast as

PS: I plan to have some sort of 20 or 24 cpu bit 2901 running in a DE1
FPGA this spring. 3 - 7 bit bytes (21/20 bit wide memory for the 20 bit
CPU) or 3 - 8 bit bytes with a 24 bit cpu. Might need to order more
Front panel switches how ever.
What have you done, with microprogramming this
part?? In your
architecture,? have you changed the microcode, create an instruction
to enhance your machine?
I would be interested in any hardware projects, stories (or even in
the FPGA, I hear its a popular thing to copy);
I hope you saw this one. Fresh on opencores:
