I've got my CoCo4... I mean... DE1 board!   :)

I've yet to setup the CoCoFPGA software but reading the docs, I like the
implementation of the 4096 color palette and 256 color mode.

It's implemented in a way that suits the CoCo3 as an extension of what it
already has.

Good work!

Looking at ebay, I found this Altera FPGA board...

I wonder if a "CoCo4" could be built by utilizing a board such as this to
act as the main FPGA board plugging in to a "CoCo I/O main board". This
board would provide all the CoCo specific I/O. The FPGA is already made and
could be upgraded.

Still new to this FPGA stuff so bear with me and sorry if I made you choke
with laughter.   :)
