@cda @davidgerard Won't happen till software becomes limited by hardware in a big way. That's how we got very efficient programs back in the #1980s. Can't run programs in more than #640k (famous DOS memory limit). Clean up your code!
Now we have machines that have way more CPU and RAM than a single main program can use. Even if they are bigger, we scale the application laterally, instead of making the code efficient.
According to Wikipedia https://en.wikipedia.org/wiki/IBM_Personal_Computer #IBM wanted to use the #m68k #CPU in the #IBMPC, but couldn't because the #Motorola 68000 wasn't yet ready for production.
That's a pity. If the 68000 was available, #MSDOS would be 32-bit and the #640k barrier would never have existed.
Future project... IBM 5160 I recently got. Has a CGA, floppy, hard disk and lpt boards. Faulty power supply I need to resolve first.
This was my first PC growing up, so a lot of nostalgia fixing one up.

A Full 640K Atari Portfolio! ...but not-so-portable-now, saddled with two Memory Expander+ peripherals. :\
