J2: PCMCIA

Integrated ejector: FCI #95620-050CA
The 68-pin PCMCIA socket conforms to the PCMCIA standard for 5V-tolerant Type II cards, and
can also be run at 3.3 V. The socket is normally de-energized; the operating system is responsible
for turning on the socket when a card is inserted and turning it off when the card is removed.
Ejector hardware is standard.
Vpp (pins 18 and 52), which is 12 V in older PCMCIA implementations, is left unconnected in
this implementation. See section 6.2.12 for electrical specifications.
