| | | | | [AI summary] The article details the author's extensive project involving the restoration and enhancement of a Macintosh 512K computer, starting with the goal of experiencing the original Macintosh's capabilities. The process included downgrading the ROM to match the original 128K Mac, installing a custom switcher board to toggle between 128K and 512K RAM, repairing various hardware components such as the floppy drive and keyboard, and integrating upgrades like the SCSI and memory expansion. The project evolved into a complex endeavor with numerous challenges and learning experiences, ultimately resulting in a more functional and usable 512K system that closely resembles a Macintosh Plus. | |

| | | | | Way back in May of 2018, I was unable to get the SparcStation 1+ to stop returning "Illegal Instruction" errors for any attempt at booting. This made absolutely no sense to anyone I asked about it, and they suggested replacing the PROM battery, because at least then we'd have fewer known-broken parts in the computer. I ignored this advice, and just stuck the computer in a corner with the other broken machines for awhile so it could think about what it did. | |
