These are the three fetchers to implement.
...
They'll look fairly different from the TMS and SMS fetchers, I think, owing to the greater irregularity that comes with the smarter RAM accesses. I might need to play around for a while.

They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.
