SITU-SOL

SITU-SOL is a programming environment for 6502-based computers that was written by hand during RetroChallenge 07/2015.

For more information, see the posts to the Bootstrap Zero blog, archived in this repo in doc/bootstrap-zero/README.md.

While SITU-SOL is quite generic, an emulated Commodore 64 was used to host it and test it during its development, so many of the instructions below are specific to the C64.

Supporting tools

This repository contains the following supporting tools, written in Commodore BASIC 2.0:

BASIC sources for these are in src; the tokenized PRG files are in bin.

Note that these programs begin writing to memory at $8100, which is normally inside the memory range that BASIC will also use — thus you are in danger of BASIC overwriting what you enter with its own variable data. So, to safely run either of these programs, you should do something like this:

POKE 56,128:NEW
LOAD "FRONTPANEL",8
RUN

Memory images

Other things

This repository might, at some point, also contain text files containing disassembled machine code that was entered.
