I was just thinking about the use of odd sayings to remember technical terms.
EMS (Expanded Memory System) = My waistline is expanding sideways. Because the 16K pages kind of expand (memory above the 640K, but below the 1M mark) sideways.
XMS (Extended Memory System) = I wish I could be taller (extend) myself to be 6 Feet tall. (Once upon a time, the minimum height for the Police was 5 feet 9 inches, which is my height)
PCMCIA (Personal Computer Memory Card International Association) = I prefer "People Can't Memorise Computer Industry Acronyms"
Electronics resistors band colour
values = Betty Brown Ran Over Yellow Grass But Violet Grey Walked. I think some of the older telco techs had much more memorable ones.
