You can use my emulator to view code execution if it's of any help. You can also modify the HP microcode and it will reassemble it and run with the changes. I used it myself to write the simulation code for the HP-10.

Thanks, Tony: I'm really looking forward to using your simulator. Thankfully, most of the work for the simulator part of this code was done previously when I wrote a C version of it. At that time, I got the java simulator for the HP-45 working in a Windows virtual machine, so I could check if my code was doing what it should do. Most of the work on this version has been (re)learning Python (which, for me, was the point of the exercise).

My C version was compiled for a few environments. I think it's probably the only one which runs on a Z80 under CP/M, and also on a TRS-80 Model I (slooooowly).
