There are many "soft CPUs" around. I wonder
how hard it is to create
a soft VAX CPU core that can be load into an FPGA. Other than to
design from scratch, I think it might be easier if we grab the
VAX-11/780, 750, or 730 schematics, and throw them into an FPGA
compiler. The 780 was implemented with TTL, the 750 with gate array,
and 730 with AMD 2901. I think the 730 scheme might be the easiest to
implement with an FPGA.
So, does anybody have the 730, 750 or 780 schematics? No, I do not
plan to start the project. I just want to make sure whether it is
feasible. Thank you.
I have full schematics for 11/780 and 11/785.
