I’m about to put what I’ve got by now on GitHub. I’m actually thinking of replacing at least all the VDI code with other functionality and perhaps even all the Cassette logic. It would obviously break compatibility with the basic partly, but I’m interesting in trying to even replace the basic statements for the cassette logic with other statements. But first… get all the available documentation merged into the T102 rom. After that I’m planning on adding labels and generally producing a clean assembly code base that can be reassembled into an equivalent rom image.
I haven’t done the hardware mod yet, but that’s what I am planning to do as well with my Rex Classic. Cheers, Erik > On 18 Jun 2020, at 19:31, Brian K.
