A project log for Sinclair Scientific Calculator Emulator

A register level TMS0805 CPU emulator on an Arduino Nano runs the original 320 instruction calculator program. A custom PCB houses it all.

After porting all of the CPU functions, the original Sinclair code starts executing in its Arduino host. It stays in a loop waiting for a key to be pressed. This is not implemented yet.

If you look closely, the terminal window says this code is running on an Arduino Uno. For coding experiments, I tend to grab the closest available Enigma Machine Simulator that is laying around on my desk.

Time for a quick tweet:
