Nonpareil status

[teenix]

I recall having problems with the HP-55 code listing and the (dot) addresses, but I still use (regC[12] * 10) + regC[11] as the RAM address calculation.

Some time ago, I found errors in the HP-55 and HP-65 microcode listings and modified them to run in the Teenix emulator, but I cannot recall what I did. I do remember I needed 5 instructions to solve the 65 problem, and funnily enough there were 5 spare ROM locations that I could use.

cheers
