Rev. A of the IDE Interface card populated with a CF to IDE interface and 16MB CF card. Jumpers select the I/O ports for IDE control and data read/write.

Description

This design is borrowed directly from Mike Riley’s 8 bit IDE Interface. The only change is the addition of some jumper blocks to select I/O ports. This is required to support compatibility of some older software of my own that used the original ports.
