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

Project Introduction:

In this project I took the main functionality of the original CFFA for Apple II and ported it to the Apple1. I added 32KB of SRAM (for non-Replica1's) so you can run Woz Basic and provided a file menu system that can read ProDOS formatted CF cards so you can move files between your Apple II and Apple1.

CFFA1 Status: March 23, 2013:

The CFFA1 for Apple1 / Replica1 / Mimeo1 is now available to order. I have built 200 boards and have them in stock. The cost is US$109.95 + shipping.

CFFA1 Status: Feb 19, 2013:

I have just shipped all of the parts for 200 CFFA1 boards to the assembly company in California! It will take about 5 weeks assemble the boards and get them shipped back to me. In the next week or so, I will open up the order site for pre-orders. I believe I have built many more units than the current demand. So anyone who wants a CFFA1 should be able to buy one. I would be able to start shipping orders by early April. The units will ship with a minor firmware update to v1.1 which adds support for the Replica1's Multi I/O board's ACIA. Also in development right now for v2.0 is FAT16 support, making file tranfers to and from your PC or Mac much easier. -Rich.

CFFA1 Status: Jan 2, 2013:

I have now ordered all of the parts for a batch of 200 CFFA1 boards! Once these parts arrive and I can build up a couple test PCBs I will send everything to the assembler for assembly. I am hoping to have boards to sell by early March.

CFFA1 Status: Dec 4, 2012:

It has been a long time since I updated the status for this project. There is finally enough demand to merit making another run of CFFA1 boards! I have order the production of another batch of PCB for run #2. I am also in the process of buying parts and will update this page again once I have sent all of the parts to the assembler. This process could take several months.


CF for Apple1
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 Mimeo 1 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.


CFFA Project Definition

CFFA1 Project Specification

  • A CompactFlash Interface for Apple1 computer and its replicas and clones
  • Support for up to 32 MB (1 drive) using the ProDOS file system. Firmware developed by Dave Lyons
  • Onboard 8K EEPROM contains operating menu and allows for user updates
  • 32KB of expasion SRAM allows running basic on Apple1's and Obtronix clone
  • Built in Menu system provides access to ProDOS formatted CF cards, from your Apple II or CiderPress
  • NOT currently compatible with A-ONE Apple1 replica

CFFA1 Run #1 Product Features Notes
Similar form factor to Apple1 Cassette interface. CFFA1 is slight wider and taller Only one CFFA1 can be used in the system at once. "T" memory select line must be mapped to $A000 on Apple1.
32KB of additional SRAM is built on CFFA1 card. Systems with additional SRAM already built in, like the Replica1, can disable or partially disable the additional SRAM.
Cost: US$109.95 + shipping Does NOT include CF memory card.
8K EEPROM holds Menu driven system capable of reading, writing, and formatting ProDOS formatted CF cards. Load and Save Woz Basic programs is a snap!

CFFA Status History

Status History

Here is a chronological summary of the project status:

July 13, 2011:

I will be making another run of CFFA1 boards after the CFFA3000 project is up and selling.

July 14, 2010:

After 3 years the first run of 100 CFFA1s has finally sold out. There were about 5 or 6 boards that never worked and I kept a couple for myself. So approximately 90 boards were sold. This was obviously not a high demand item, but I was happy to make something for the Apple 1. If there is enough interest in another batch I would consider it. Please let me know you are insterested in a second run by sending me an email using the following link: Send E-mail.

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.

Oct 22, 2007:

I will be showing off the CFFA1 interface card for the Apple1 again this year at VCF X on Nov 3 and 4, 2007. Stop by and say hello if you can make it to the show.

June 1, 2007:

All paid order for CFFA1 boards have been shipped on June1. Included with the CFFA board is a CD with a copy of the manual in PDF format. Also on the disk is a copy of Woz's old Apple1 basic and two games: LUNAR and basic games STARTREK. I appreciate everyones patience with me getting this project done.

May 25, 2007:

I am on plan to ship all the current CFFA1 orders by June 1. I have programmed the CPLD logic and EEPROM firmware into 23 units and I am putting the final touches on the manual. The manual for the CFFA1 will only be available in pdf format. If you need a different format, contact me via email and I will try to accommodate you. I will be including a CDROM with your CFFA1 that will have the manual on it.

May 6, 2007:

Feedback from two testers of the production lot has been good.
Progress on the manual and final release version of firmware is going slower than planned. The API interface has been added to the firmware, but still needs to be documented. I have revised my ship date to be June 1, 2007. This board has been 30 years in the making so I hope everyone can be patient for a few more weeks.

April 20, 2007:

I have received the assembled CFFA boards!!!
I have tested a couple random boards and they appear to be working fine. More testing needs to be done, and I have to finish the manual and get the 1.0 release of the firmware ready.

March 24, 2007:

I have just begun accepting pre-orders for the CFFA1 interface card. I soonest I would see cards back from the assembler is about 3 weeks from today. This will translate into about 4 to 6 weeks before customers start receiving orders.

March 19, 2007:

All of the parts and PCBs have been shipped to the Assembler. The assembly process will take about 3 weeks to finish including shipping back and forth. Assuming nothing is lost in shipping, I shold have a batch of 100 CFFA1's to sell in about 4 weeks. Pre-ordering will begin in a couple days. I just need to finish up the web site first. If you contact me about this project you will be contacted via email as soon as I am ready.

March 11, 2007:

Well, all of the production PCBs have arrived and most of the other parts too. I have built one board from the production lot and it seems to be working great. I still have a couple more tests to run. If all goes well, I will be shipping all of the parts off to FlexOne next week sometime. Once they are in the mail, I will open up for pre-orders of the CFFA for Apple1. The run of boards will be a total of 100 boards. As always, some boards will be bad, and I will keep a couple, so I expect to have about 90 boards available to sell.

Feb 16, 2007:

I have just ordered a batch of 100 PCBs for the CFFA1 project. I will be ordering all of the other parts next week and in about two more weeks I should have all the part needed. I will then be sending all of the parts and PCBs to FlexOne for assembly. Once I get my order site up and running I will send out an email to announce that I am accepting pre-orders.

CFFA1 FAQ

FAQ

Q: Are you taking orders?
A: Yes. Run #2 of CFFA1 is now available. I have started building run #2 of the CFFA1 as of Dec 2012. I hope to have something to offer in March 2013.
Q: Will the CFFA1 work with Briel Computers' Replica1 and Mike Willegal's Mimeo1?
A: Yes. This board will plug directly into the Replica1 TE and the Mimeo 1. If you are using the older Replica1 SE, you will need one of the three slot expansion slot boards.
Q: Does the CFFA1 support IDE harddrives, like the old CFFA for AppleII cards did?
No! It is only a CF card interface.
