PC Card Manager 2.0 supports PC Card and Socket Services on the PowerBook 520, 540, 190, 5300 and 1400 series. PC Card Manager 3.0 supports PC Card and Socket Services on all machines later than the PowerBook 1400 series. At the time of writing this document, this includes the PowerBook 3400 series and the PowerBook 2400 series. Developers should assume that all future PowerBooks with PC Card support will use PC Card Manager 3.0 or greater.
PC Card Manager 2.0 supports 68K PowerBooks (the 520, 540, 190) and some PowerPC PowerBooks (the 5300 and 1400). Multifunction cards are not well supported. The effort needed to get a PC Card to work under 2.0 involves writing an enabler and a classic 68K driver. There is a default serial driver which works with most serial modem devices. We do not anticipate releasing any new PowerBooks using PC Card Manager 2.0 outside these product lines. PC Card Manager 2.0 supports the PCMCIA specification 2.1.
PC Card Manager 3.0 supports PowerPC PowerBooks with a PCI architecture. At the time of writing this document, these are the PowerBook 3400 and PowerBook 2400. Multifunction cards are fully supported, and are as simple as generating the proper 'ndrv' driver for each function in the card tuples. The effort needed to get a PC Card to work under 3.0 involves writing an enabler and a PCI style 'ndrv' native driver. There is a default serial driver which works with most serial modem devices. PC Card Manager 3.0 supports the PC Card Standard as published jointly by PCMCIA and JEIDA.
