- PCMCIA 2.0 is the most recent version. It includes both an SRAM
- interface and a PC-like 8/16 bit I/O interface. The standard also
- includes a bunch of software stuff.
-
- I'm not sure exactly what was in version 1.0, but I suspect that
- this might mean memory only, without the I/O capabilities.
-
- Size-wise the cards a "credit-card" sized. The interface supports
- up to 64 M-byte of address space, but unless the system has a 32-bit
- address bus, probably only part of the space is accessible, perhaps
- with a page register to allow access to the remainder.
