I remember this from the "old" days, but never investigated it.
I never looked into it, so never learned about it.
Trying to wade through a Wikipedia article about it, but it's a bit over
my head at the moment.

On the Atari, "Bank" would be a section of memory substituted in place or switched into the same area. Ramdisks do this as do Supercarts but each is using a different method and memory area, both bank switching blocks of data by various means. Very similar to switching Operating Systems by means of several different eproms that you select with a switch prior to booting. Just another flavor of bank switching in other words. If the light doesn't even glow a little now maybe you could come back with a better question? One that deals with what you can't grasp about it.

This answers my question, Lee, thanks. It came to mind when I was
having a discussion in the Apple support groups about virtual memory.
I'm surmising that, on the ST/TT line, programs like Revolver are doing
essentially a similar process, except it stored the entire contents of
the RAM to the disk drive, not just portions.
