Chip versions(8086)

The clock frequency was originally limited to 5 MHz (IBM PC used 4.77 MHz, 3/4 the standard NTSC color burst frequency), but the last versions in HMOS were specified for 10 MHz. HMOS-III and CMOS versions were manufactured for a long time (at least a while into the 1990s) for embedded systems, although its successor, the 80186/80188, has been more popular for embedded use.
