Not sure how that would be approached, but things like the scroll offset register stuff, and things like the “64/128 column” screens and such are a mystery except for a handful of programs that used them. Stuff like that seems to break emulators early on. A way to test could be useful for FPGA, emulation, etc. > > — A > > > As a hardware guy, I've got to help throw things against the wall. GIME replacements are a growth industry since you can't buy one new. Which also makes them a moving target. Maybe a GIME tester runs after the Diag cart verifies CoCo is healthy enough to load tape/disk? That code could start as an outline of most used functions, expandable to enclude oddball modes, and GIME X/Y/Z could add tests for new functions. -rick -- Coco mailing list [email protected] https://pairlist5.pair.net/mailman/listinfo/coco
