Project: CFFA for Apple 1, Replica1, and Obtronix Clones

Project Introduction:

I am now accepting orders for the CFFA1 interface card for the Apple1/Replica1/Obtronix Apple1 clone. The CFFA1's is priced at US$89.95 + shipping.

CFFA1 Status: July 6, 2008:

I have reduced the price of the CFFA1 boards for the Apple 1 computer. Futhure saving can be found at Briel computers when you buy a CFFA1 card from them in combination with a Replica 1 computer.

This is an example of a hand-soldered CFFA1 board from the first batch of production PCBs. Replica 1 TE users can now plug the CFFA1 directly into their Replica1, as this version now integrates the standard 44 pin edge connector. Older Replica1 owners will need the slot expander. Apple1 and Obtronix Clone users can plug my CFFA1 card directly into their hardware.

Below is a sample of the menu generated by the current firmware. The firmware allows reading and writing ProDOS formatted CF cards. You can move files between your Apple // CFFA or CiderPress to transfer programs to and from the Internet. There is also a simple API system somewhat like ProDOS's MLI for interfacing to the underlying code. Keep in mind that this is NOT ProDOS or even an operating system, just a menu system with all the needed code to read and write the prodos file system on the CF card. It also automatically handles reading and writing Apple 1 basic files including the zero-page range.

Currently the Menu firmware has a few limitations, including a single level of directories, and access to only the first drive or partition on a CF card. It is possible that these limitations will be removed at some future time.
