Version 1.1
Orcad based. Note: There is a nasty bug in this schematic. The 74HCT245 databus buffer is backwards.
The B side should be connected to the Apple Bus not the A side. Will be fixed in Version 1.2. (Date Found: 02/07/02)

Third Party software
Dave Lyons' GS/OS Driver
- CompactFlash v1.0 in Shrinkit format
- CompactFlash v1.0 in Binascii format
Note: The CFFA card will work under GS/OS without this driver, but
additional volumes and significant speed increase result from using the
driver. You can also download the same GS/OS driver files, including source code, from
Dave Lyons' Web site
