For those who aren't aware what PCMCIA stands for: People Can't Memorize Computer Industry Acronyms
And obviously PicoPCMCIA means "very small people can't memorize computer industry acronyms".
(Or possibly s/computer/complicated/, that's how I remembered it at least.)
I thrifted a shirt once that said it stood for "Peppy Cheerleaders Move Crowds into Anarchy". Wish I still had it!
"For those who have forgotten..."
If you want to refresh an old memory, it actually stands for "Personal Computer Memory Card International Association" but nobody knew that. And it was later called 'PC Card'... then there was the faster ExpressCard that wasn't backwards compatible.
It was fun being able to expand your computer's IO capabilities by adding on a network card, modem, USB, FireWire, etc. with these modules. It's similar to Framework's little USB-C-based modules, though those modules are just too small for a lot of circuits without a very creative design.
