Online HP-45 Emulator - First calculator with a shift key

[van2z]

After building the HP-35 calculator, I was looking if there was any low hanging fruit for me to reuse the same code. I found the HP-80 used exactly the same hardware, but I couldn't find the ROM.

I see Brouhaha seems to have manually copied each assembly instruction from the original patent into his Nonpareil code, but I don't have an easy way to compile that to see the ROM binary. If anyone can do this, it would be appreciated.

Moving on after the HP-80, was the HP-45, for which I was able to find the ROM binary, also from Brouhaha, here.

The hardware here was also very similar. The main difference is the inclusion of a "data storage" chip, giving the calculator an extra 560 bits to use. Here it is:

I have never used this calculator before. I see it starts out using fixed notation 2. If anyone has used this calculator before, please let me know if it is functioning properly, or if you see any issues.
