Project: CFFA for Apple II, II+, IIe, IIe enh, IIgs

Project Status:

The CFFA3000 Run#4 is Sold-Out. Any outstanding unpaid orders need to be paid for by March 25, 2016. All Run #4 orders will be shipped before the end of March. If there are any extra boards after everything is finished, I will put them up for sale on ebay some time in April 2016. Surely by now the world-wide demand for CFFA cards is filled, but if you would like to express your interest in a fifth run of CFFA3000 cards, please use this email link to let me know.

As of today, there are a total of 24 CFFA3000 boards left in stock! Order soon before they are all gone!
Once I have shipped all of the CFFA3000 boards I will look into making switch covers availables to customers of previous runs. I will send out an email to existing customers if/when they become available.

CFFA3000 Run #4 is currently shipping to customers. We have shipped 97 boards as of today. There are 117 still available to order from this batch 500, and 91 remote switches out of 300 total. Remember that you can check your order status here!!

The 4th run of CFFA3000 boards are ready to order. Click on the Order Form link to the left. This run is 500 boards in size. We will be shipping 100 boards per month. Order soon, as they will go fast. About 200 boards have already sold in the first 9 hours of availablity.

CFFA3000 Run#4 Update: All of the parts and PCBs have been shipped to the board assembler in California.

CFFA3000 Run#4 Update: The PCBs and all parts for the next run of CFFA3000 boards have been ordered! I am still on schedule for November 2015 availability.

Here are a couple videos about the CFFA3000:
1) A high level introduction what the CFFA3000 does.
2) An initial setup tutorial for getting started.

Project Introduction:

This page describes a project to create a CompactFlash / USB-Flash Interface card for Apple II computers (][+, //e, //e enh or //gs) that started back in 2002. Over the years I have build 2000 CFFA cards in 8 batches. The card is in its third generation which dropped the IDE support and added USB flash storage support. It also supports FAT16 and FAT32 formatted devices for easier transfer to/from your PC. I did the original wire-wrap prototype over the span of several months. This project is very much a case of old technology (the Apple II computer) meets new (CompactFlash cards and Altera CPLDs). My reasoning for this project is described in detail in the Background section, but suffice it to say, I wanted to be able to pull out my old Apple II and use it from time to time to reminisce about the early days of personal computers. I wanted a reliable way to store my Apple II programs and data files for many years to come. Due to the long term reliability prospects of floppy drives, and my general laziness, I decided a mass storage device is what I needed.

CFFA3000 project Introduction:

At the end of 2008 I sold out of my 6th run of CFFA cards. Instead of making another batch to meet demand, I decided it was time to design something new. The main shortcoming of the CFFA card was its lack of support for operating systems other than ProDOS. It was not possible to store and run DOS 3.3 games from the CFFA. So I decided to try desiging a new CFFA that would have these new features: 1) Floppy disk emulation at the nibble level and 2) USB flash drive support for storage of .dsk image files. The effort to design a new CFFA now called the CFFA3000 took about 2 years. The long development time was mainly because this is a hobby for me and not my normal job, also the CFFA3000 is about twice as complex as the orginal CFFA.

Great tool for CFFA users:
All CFFA owners who use Windows... Andy McFadden has come out with an excellent tool called: CiderPress. This tool will allow you to read and write your CFFA formatted CF cards right on your PC. It will make an excellent backup tool. Check it out at Andy's Site

Information about the "3 jumper" fix for older CFFA V1.2 cards: (Runs 1, 2, and 3) A problem as been found that explains why many CompactFlash cards have never worked with the older CFFA cards. I was motivated to find this problem when I realized that SanDisk 256MB cards were not working properly. To summarize, the address lines were changing near the end of the ATA bus cycle seen by the CF card. This seemed to be tolerated by the smaller SanDisk cards, but not the 256MB card or many other brands, like Lexar. So after much debugging I found the problem and was able to fix the problem with a new release of the CPLD logic (V1.4), and the addition of 3 "rework" jumper wires to the board.
