Well, I know some cards are mechanically different, so
that a card of
type X can't be plugged into a socket of type Y (though the converse
works fine). I'm not sure which is X and which is Y - I thought one
was PCMCIA and one was PCCard, but I'm not sure of even that much - and
I'm not sure what the differences are besides mechanical, though I've
heard enough to make me think there are such differences.
It started off with Poqet using them, before they were completely
standardized and NAMED. Is Poqet "PCMCIA"? Almost. Maybe. Sometimes.
Then, the major difference for a long time was just the THICKNESS! A
"type 2" card is too thick to fit in a "type 1" slot.
I'm sure that as they started using it as a BUS, for network cards,
modems, etc., that additional incompatabilites were developed.
And don't get me started about "DB9"
connectors!
Although there can be alternate pinnings, to me THAT means a DB25, with
pins 1 through 8 and 20.
"DB15" is worse! Is that a DA15 or a DE15? I once needed a DE15 to
DA15 adapter to "repair" a video projector whose cable had been abused.
(I did not want to risk having a college administrator catch me soldering,
and wanted "non-adapting" cables so that unqualified staff could do the
next repair) The EBay vendor insisted on calling it DB15 to DB15!
