70s - kHz, not MHz

Authored by: Anonymous on Wednesday, January 02 2013 @ 01:28 AM EST

Mh.

The original 8088 was clocked at 4.77 MHz. Not KHz. Not GHz. And the 5th
harmonic of the master clock ran interference with some FM stations if not
properly shielded.

I designed stuff on 4/8-bit CPUs running at 250KHz. They were already doing
useful things, and were a big step forward from earlier generations that didn't
have RAM but only disk memory; they were fun when debugging real-time apps like
controlling a printer carriage :-)

A 4.77 KHz version of the 8088 would be slow indeed.
