I recently have been getting into making a lot of small swift apps for personal use AND now have MacOS 7 and 8 running on my iPad since they’ve added mouse pointer support. Excited to dig into this article!
The first is more stable, and recently got the pointer support added, but doesn’t go up to MacOS 8 AFAIK. I copied a bit of the stuff from that to the MacEmu one to get the pointer working ok.
I don't know if this is the way, but ~20 years ago I was curious about running emulators for 68k Macs on PCs.. there was vMac which emulated black&white Mac Plus, and basilisk II which emulated a macII. They could both run system 7. That was true circa 1998. I imagine the hardware needs are not that high.
