(PC-1211) Engineering format

[robve]

I've created a new GitHub repository with an improved version named "prolly" (program roll-y) to reduce the code size after installation on a machine, taking only about 220 bytes of RAM space. The repository includes the full documentation in a README and the annotated assembly source code. Bootloader bas and wav files are included for the Sharp PC-1350 and PC-1360 to install the program.

The program should be portable to the Sharp PC-126x and PC-1403 with some modifications. However, I don't have these machines to work with until much later and the PockEmul emulator doesn't appear to offer a way to load machine code for testing. But perhaps I find a way. Nothing is impossible, after all
