Did you mean 8088 here?
- dwheeler 7y agoYes, 8088. Thanks for the fix. The 8088 was a 16-bit CPU with an 8-bit bus. The 8086 was a 16-bit CPU with an actual 16-bit bus.
- Accujack 7y agoInterestingly, the original "sx" designation for Intel 386 chips (80386sx) meant the same sort of thing... the 386sx was a 32 bit chip with a 16 bit bus. The dx was 32/32. A product generation later, Intel changed what this meant to indicate whether or not the CPU had an on-chip FPU.
