[Coco] CoCo3 FPGA project analog boards

[Zippster]

I don’t know, I’m new to the project myself.  But if that’s true that
would possibly eliminate the need to modify new boards and would
be good, though then an analog board would be required.

Am I right to conclude that if someone had a DE-1 with the "wrong" memory chip, they could still use the Analog Board to add 4MB of full speed memory, and simply not use the slower 512K on the DE-1?
