[TUHS] DCJ-11 processor with 20k FPGA

[Jason Stevens via TUHS]

 the code in the repo is for the FPGA, the processor that is strapped to the
FPGA well it runs the real code.

It's like the 'minimig' Amiga emulator platform, a real processor, and FPGA
to do all the IO heavy lifting.

So it's not 100% FPGA but you are executing code on a real processor so you
aren't exactly full emulation either.  And it doesn't cost a fortune,
assuming you can find one of these ancient microprocessors.

I just had a look at it, but he doesn't show the code, which runs on the

TangNano?
