[Coco] Stable colours

[Luis Antoniosi (CoCoDemus)]

Well if you go for a DE0-Nano it costs 80 dollars. The daugher board is
pretty simple, 10 dollars and the components pretty available: bunch of
resistors, a variable resistors, a small protoboard and a VGA connector and
a stackable 40 pin header. Got everything from a local store.

But it could be done on a CPLD for reduction costs. I don't have the tools
for CPLD development, nor I don't make an idea how to solder a FBGA chip .
Mark Marlette ? Darren A. ? Who else ?

It would require a CPLD with 550 LEs, 16K bits of RAM and a external SRAM
with 512Kbytes or a SDRAM as the Altera. For a SRAM the code must be
changed since the DE0-Nano has only SDRAM.

Don't know if that would beat the 80 dollars asked by the Altera. But Daren
made de SDC for a 50 bucks cost. Maybe that would be a reasonable price.
