I remember using a Timex/Sinclair 1000 with the TV monitor. When the system was running in "fast" mode I could turn the volume of the TV up and listen to a few different hums as it was doing things. I.E. if it was just doing a large for loop, it was one pitch, saving to tape was another pitch, writing to the screen was yet another pitch, and so on. Rumor has it that when the 100MHz 486 and Pentium were coming about they were "broadcasting" on top of a radio station in the area. Drivers listening to the station got a lot of humming when they drove past the Intel sites... Fact or Rumor?

FWIW: The T/S 1000 "fast" was faster because the CPU did not do screen updates, where as "slow" when it updated the screen in time with the print statements.
