The bottom line is that for professional work with S3e the $300 USB JTAG
from Xilinx is pretty much the only game in town. But for hobby purposes
where speed is not very important and you have a PC with a real parallel
port the $12 cable is just as good.


It's a shame that the JTAG to PC interface has never been
standardised. But then, you get Webpack ISE for free, so I guess they
recover those costs in the cable.

I'm pleased you've come up with an alternative non-developer way of
reprogramming the board. I was going to suggest that a 'core' firmware
be developed that allowed access from the actual Apple II host, but
your solution is just as good, if not better.


I was hoping for a way to load the card's configuration while
still in the slot by means of Apple II software...  This would
certainly be much easier if a part of the FPGA was "protected"
as it did its end of the reconfiguration.

An alternative would be for the Apple II to copy a configuration
file from a file system device to storage on the Carte Blanche,
then, via software, trigger a reload of the new configuration.
