"PrintCopyright trap"

Posted by: atax1a on 2025-06-27 22:40:09 Hey all, Prompted by the G3 ROM egg hunt, we revisited the MacKiDo page on easter eggs and saw the one about the PrintCopyright trap. Nobody seems to have written the requisite code, though, so here's a stuffit archive containing code that does it, and a screenshot of what it looks like — nothing fancy, it's just 3 calls to DebugStr(), but here it is.

Posted by: atax1a on 2025-06-27 22:55:32 nb: running this requires a debugger to be attached, but MacsBug doesn't work in DingusPPC (pretty sure it doesn't work in SheepShaver either). It DOES work in Qemu, in both MacsBug and Jasik's Debugger. 🙂

Posted by: joevt on 2025-06-27 23:08:49 MacsBug is supposed to work in DingusPPC. If it doesn't then that means there's stuff that needs fixing. SheepShaver on the other hand, does some stuff that is maybe not compatible with debuggers.

Posted by: atax1a on 2025-06-27 23:48:53 ah, mea culpa, we meant the web-compiled DingusPPC on Infinite Mac. We haven't tried Dingus as a standalone executable.
