I think you are correct. I had assumed that the panel only displayed the normal 360
registers, in which case
the VHDL could easily route these to a panel, but on reading the 360/65 Functional

I can see several registers are displayed that are not mentioned or defined elsewhere so
you would need a
Set of ALDs for the 65 (or possibly a 67 as that?s basically the same machine) to get a
full panel display. It would
Also be nice to see what is on the roller selector switchs as that page in the manual has
not scanned very well..

Sure, a generic one would be simpler, but the point of doing an accurate one
of a specific model (65 in my case) is to accurately drive the panel that shows
the internal registers and opening of gates. find 360/50 ALDs...

It actually might be easier to produce a generic S/360 clone in FPGA
using the POP rather than individual ALU's.
Having built a very simple CPU (in VHDL not Verilog) and planning to
start on a more complex (Ferranti Pegasus) Of course it wouldn't be
cycle accurate, but perhaps that wouldn't be important.
