| Bare Metal Classic Mac 'OS' and SDK! | |
| Posted by: Snial on 2025-07-15 02:24:12 Well, this is rather impressive! "Ken Designs" has developed a bare-metal SDK (compiled in gcc) which can boot on a classic Mac. He's used it to write a chip-8 emulator (which is fun, but not my primary interest). Check it out. It's also on Hackaday. I'm looking forward to seeing the SDK released when he does. I think one implication is that it doesn't have to rely on the low-memory layout used by the Mac ROM and means you could run an 'OS' in User mode instead of Supervisor mode (making preemptive multitasking easier which also implies one could port a Sinclair QL ROM to it, which I would find appealing). | |
