http://www.homebrewcpu.com/ http://www.homebrewcpu.com/ User/data segments, 16bit data operations, user/supervisor modes, address translation, mmio and DMA. 8meg address space, 128K per process. Runs Minix (Precursor to Linux). 200TTL logic chips. How quickly do you think you could build that? My bet, is if you had a dedicated group of people within 2 years you'd have a mhz computer again. It's easier the second time around.
