All you need is a JTAG cable to connect between your PC and the Carte 
Blanche and Xilinx ISE Webpack software (very powerful stuff and free).
Verilog the programming language I use has a syntax similar to C but 
programming hardware is quite a bit different than software.  It was 
hard for my feeble brain to deal with the fact that everything is 
happening at once.  Take a look at my site for more information on how 
I've stumbled along learning this stuff.  I haven't updated it since I 
started playing around with Super HiRes on the //e but will when I get 
it all together.

Yes, my stuff is just an extension of what Alex Freed and Steve Howell 
did.  My main "claim to fame" was adding Super HiRes to the Carte 
Blanche VGA output on my Apple IIgs.  With that I came up with a cable 
and code to output 12 bit video so that all 4096 of the SHR colors could 
be displayed.  It seemed to me that it wouldn't be that hard to add SHR 
to a //e, but I mainly use the IIgs and never got around to it till now.

GS video conversions would be nice additions to your already great site.

I just plod along with whatever hits me as fun at the time.  Right now 
this is fun.
