Interesting Caveat For PB 500 Series PCMCIA Expansion Module
Posted by: Paralel on 2014-09-14 11:36:49
I came across this and thought it was interesting:

http://support.apple.com/kb/TA35383?viewlocale=en_US

"Apple does not recommend that any PCMCIA module be used with PowerBook 550c computer. The PowerBook 550c is available only in Japan."

Anyone know the reason behind this?

According to EveryMac.com, it sounds like the 550c uses a different module than the 520 or 540.

http://www.everymac.com/systems/apple/powerbook/specs/mac_powerbook550c.html

Expansion Slots: 2 Type II PC Card* Expansion Bays: 1** Details: *2 Type II PC Card (1 Type III) expansion slots provided by PCMCIA adapter in a "swappable" bay (M2995LL/A).

**This model has a custom "swappable" bay that can be used to hold a second battery or a PCMCIA adapter along with other options.
Question is, does this model number for the PCMCIA ( M2995LL/A ) matches the ones for the 520/540 or is it different?

It matches the one for the US 500 series, and people have successfully run Rev C cages meant for the 540c in the 550c. I wonder why Apple warns against it.

I'm just speculating on this one by saying that Apple had/has a PCMCIA cage for the 550c in Japan which costs more money to get from them. But since that notice is almost 20 years old now, I would not worry it. If it matches one of the cages, then that's the cage to use.
