Ok, I had to do it...

Here is the CPUV function that returns 1 if the CPU executes PC=(A), otherwise 0.

I got 0 on my oldest HP71s, but 1 on my 2842Axxx machine.

Note that both Emu71/Win and Emu71/DOS return 1 since they support the new opcodes.

Forth/assembler needed to enter and assemble the CPUV keyword.

When you don't like to fiddle around with the Forth/Assembler module like me, I added the original sources, sources which can be compiled with the HPTOOLs package and a compiled L71 file for importing with the DOSLINK interface.
