With Alex's new FPGA programming from SD card option, the upgrading of
the card's FPGA will be very quick! and very easy to keep track of the
cards different configurations (ie - keep the bit stream configuration
on a labeled SD card as a back up). We have also put together an Apple
II insystem JTAG adaptor as an experiment, which we'll try out after
CB, but the concern is, it will take a long time to upgrade the FPGA.
The upside (for the patient), is that it is insystem and uses the
joystick port to communicate with the FPGA (ANx and PBx).
