For people with technical questions about their CFFA Interface card. You can use this forum to communicate with me and with other CFFA users. If you are posting a problem, please be as detailed as possible, including any necessary sequence needed to cause the problem, your system information and any error messages.
You made reference to trying to come up with a way to update the CPLD from the game port in order to change the logic to allow for updating the config menu without removing the jumper, when updating earlier cards to firmware 2.0.
Has this been done, or do we have to send boards back to you to be updated?

Getting the CPLD JTAG code from Atmel to run on the Apple II has proved harder than I had hoped. It is a bit of a black box and hard to debug.
I have stopped trying for now so I wouldn't wait for that solution if I were you.
Keep in mind that you don't really need to update the CPLD logic, unless you want to. It will only get you the convenience feature of not
having to remove the Write Protect jumper when saving changes made on the config menu. Well, and only small bug fix that seldom
caused anyone trouble.
But the two ways that come to mind just now:
1) Send me your board and I will update it for only the cost of the return shipping.
2) Buy a JTAG programmer called a ByteBlaster or ByteBlaster II, or ByteBlaster MV. I bought one
off ebay for about $15. And it works with a program called AtmelISP which requires windows.
You will need a PC with a parallel port to connect it. Do they still make those?
