My understanding (probably wrong) is that pcmcia was based off the ISA bus and then pc card updated to pci based and express card was pcie

Close! The PC Card rename was because people were confusing the name of the association with the specific form factor.

PCMCIA and PC Card = ISA

CardBus = PCI and ISA - slot was backwards compatible so you could use a PC Card in a CardBus slot

ExpressCard = PCIe

That's also not a perfect recollection, but is what my recollection was until I was looking up this history in the past week and found this nugget and posted it elsewhere. Quoting myself:

>So we know these were originally called PCMCIA cards, then later PC Cards, right? Well, I think I might have found the first mention of PCMCIA in PC Magazine. It is in a Dec 1991 column by Dvorak where he "introduces" the "PCMCIA PC-Card". Here's a quote, "In fact, the card should be referred to as the PCMCIA PC-Card, or the PC-Card for short. PCMCIA is the Personal Computer Computer Memory Card International Association (Sunnyvale, Calif., 408-720-0107), and it's the governing body that has standardized the specifications for this card worldwide. JEIDA works with the PCMCIA; it's specifications are identical."

>So at least according this Dvorak column, these were ALWAYS properly called "PC-Cards" (he used a hyphen), but early on people definitely were calling them PCMCIA cards and I remember the shift to everyone later (much later than this 1991 column) calling them PC Cards.

Ah, completely forgot about CardBus. That was a fun time when we also had NuBus kicking around on some older Macs, too.
