I don't know how they will be able to manufacture CPUs on Mars, I'm guessing 8-bit CPUs will be more possible than modern day CPUs. I think even Motorola 68K will still require advanced manufacturing equipment to transport to manufacture.
I guess with close to 50 years of CPU design knowledge they would be able to design a decent 8-bit CPU with 16-bit address space. Maybe they would use first 512 bytes as a data/code cache to speed up certain calculations (trig functions) (Not a EE, studying Mechanical). Although there is a lot of code available for Z80, 6502, 8080 CPUs.
- reitzensteinm 2y agoI think rather than experimenting with fabbing on Mars, you would probably be better off sending an absurd amount of CPUs from Earth. A 300mm wafer weighs 150 grams and can fit 30k Raspberry Pi Nano CPUs on it, 2mm^2 on 40nm. If you send up a wafer per person, which can be laser cut and placed into more easily constructed electronics locally, you've got hundreds of years to solve the fab problem in a worst case, Earth no longer exists situation.
