16 bit video RAM. 16 bit audio. 16 bit processor. Seems like
a good match.
DRAM is more difficult to interface and is not as fast.
12 nS RAM means 50 million pixels a second. 1/2 million actual
pixels (800 X 600 or is it 600 X 800?) mean 100 Hz maximum refresh.
Not tops. But decent.
Minimal memory manager needed.
Slow clock for startup under EPROM. Fast clock for
running out of RAM.
