Even my 2010 Toshiba laptop only supports the latter PCMCIA-II standards.
lol, remember getting one of the first PCI-E pcmcia slots. Never could use it, as nothing was available at decent prices.
Moved on by time they were affordable.
In regards to 12v, never heard of 12v PCMCIA. Did however see this.
Supply Voltages
- 5V DC +/- 5%
- 12V DC (when required for PCMCIA devices as programming voltage)
Supply Current (absolute Maximum for PCMCIA cards)
- 1A at +5.0V
- 500mA at +12.0V
(Maximum allowed value according PCMCIA specification for inserted cards)
Apparently, 12v is used for programming.
