How about the same thing on a 68K emulated with an FPGA? (ok it will probably cost more than 5 pounds)

- rbanffy 2y agoUnless you want cycle-accurate interfaces, it's pointless. Software can provide more than good enough performance and be a lot more flexible at that. As microcontrollers get faster, the cycle-accurate timing becomes less relevant, as you can still match external timings with software and have the support of an RTOS to help with that.
- Wowfunhappy 2y agoWhat about power consumption? Could you have a tiny Mac which runs approximately forever on a single charge?
- rbanffy 2y agoI imagine the power consumption of the compute part would be dwarfed by the display in any case.
- Wowfunhappy 2y agoI was imagining you'd still plug it into an external display. I guess you could fairly argue that defeats the purpose of a battery, though... Although, it might be cool with e-ink, low refresh rate notwithstanding.
- rbanffy 2y agoE-ink can have better refresh rate than the LCD of a Mac Portable. And would also be readable. Would be interesting to see how the ROM deals with changes in display geometry (the Portable wasn’t 512x284) - how hard would it be to make a 1024x768 portrait Mac or some other versions that never existed.

Mini vMac lets you change the emulated resolution: https://www.gryphel.com/c/minivmac/options.html#option_xres https://www.gryphel.com/c/minivmac/options.html#option_xres. Works very well in my experience.
