I think fab a real chip would be a better idea -- but then how many
people want a vax?
Ok, I don't . Looking at a different post the vax has large microcode,
so a FPGA that
can have internal ram be configured as micro-code tables would be handy.
extra ram for your register file too.
No but they do here:
