Norbert's HP calculator emulators for 6502 micros

Not @NoLand but Norbert Kehrer:
HP Calculator Emulators for the Atari 800XL and for the Commodore 64

I wrote emulators for [HP-35, 45, 55 and 80] for the Atari 800XL and for the Commodore 64, which simulate the 4-bit HP calculator CPU to interpret the original program ROMs of the four models.

Also of note, an emulator for the IBM 1510: http://members.aon.at/nkehrer/ibm5110_js.html

and some experiments in direct translation of 6502 code into JS runtimes. (I saw him once in a talk on the latter topic.)
