Dumping Sharp PC-1500 ROM modules
I mentioned in another thread recently about dumping a couple of Sharp PC-1500 ROM modules. I have uploaded the preliminary results to GitHib. The raw files, the files converted to source/text (BASIC) and some notes are included.

PC-1500 ROM Modules

I will be putting together a bit more information about how the process works and making a video. One of the modules has four banks and uses a couple of flip-flops to switch banks. This is done to fit a 64K BASIC program into a 16K ROM address space.

It might be interesting to upload the program from the Pygmy module to the PC-1500 as text (tokenized on the fly by PC-1500). This can't be done with the banked cart though Smile
