Wow, biffo! And I missed it!
Anyway, I hope everything is all tickety-poo now, and that this little
post dosent cause anymore hoo-har.
But I finished the Apple II in system JTAG programmer - this is purely
a fall back gadget. My only fears are for anyone that loses their FPGA
flash config, and isnt in a position to reflash it. It may take half
your sunday afternoon, but it means you and just your apple can get
back to business by reprogramming the affected card. The SD based
flash programming is the way to go for sure! So quick and easy to
manage hardware libraries. Considering how much fun you can have
knocking up your own hardware designs for cb, being able to assure
people they can reflash their card one way or another is what im
trying to create here.

It still needs code from the Apple II side. It uses AN0, 1 and 2 for
write, and PB2 for read. So you can still use your external joystick.
