New HP92 Emulator - teenix - 07-19-2022 04:03 AM

Hi all,

After fiddling with how the 92 internals work and how the switches interact with the ACT, the new HP-92 emulator seems to be working ok. This one runs the real HP microcode read from the ROMs from a HP-92 using a home built ROM reader.

If anyone is interested in running it on a PC, the link is here...

Great work.

Compare to the original simulator this microcode level emulation you can see the screen flickering.

Thank you.
