Started a new module to support the VGA component of SPAM-1.
I wanted 32KB of dual port ram for video but wasn't willing to shell out for it. I found a couple of 16KB PLCC modules so I need a board to support them as part of SPAM-1 and the new sub-project is a PCB to create a 32KB module that's R/W from the CPU side and Read-only from the GPU side and fast enough for 160x120 approx video.
It's a work in progress.
I want it to fit amongst my breadboards so it's size constrained.
