NatAmi 68070 design draft

Hi Crumb,

Is there any brave FPGA coder who wants to include 68020 instructions to Tobiflex "FAMPIGA"? :-)

We toyed with this idea once before:

Probably not TOO difficult to make a 68020 "CODE COMPATIBLE" version, but with 16bit data bus and minus 68020 goodies like:

256byte caches.
three-stage pipeline.

Odd-word aligned data is probably the biggest enemy, though most high-level compilers are unlike to produce such code.
Normally there would be a compile option to avoid producing odd-word aligned data anyway.

"It was only when the motherboard entered final prototype that the design was demonstrated."

Presumably they finished the HDL code used on the 2000 prototype model.
From the pics it appears the 2000 prototype used 3 small (by today's standards) Altera flex devices.

Does anyone know if the HDL code the BoXeR team wrote still exists, or who may have it/where it might be?
Perhaps they could be persuaded to release it?
