Engine BASIC Memory Map

Hawk

It only just occurred to me that there is no memory map for Engine BASIC.
I was pondering the idea of being able to move the address of the start of screen memory to scroll around a larger bitmap and I realised that I didn't even know if that memory address existed or was accessable.
There are PEEK and POKE commands which imply that there may be a need, but what does the memory map look like?
I know, in general, Engine BASIC provides an extensive list of extra BASIC commands for performing most operations, which is very different from how Commodore implemented the BASIC. I grew up with Atari BASIC, which provided extra commands for graphics and sound, but you could still access the registers directly if you wanted.
Are there any registers in Engine BASIC that can be read/written to?

Hawk Atari BASIC guy from way back in the day, too 🙂 Just in case you've never used it, Fast Basic by dmsc, for the Atari 8 bit machines, it heads and shoulders above other Atari BASICs. It wipes the floor, speed wise, with TBXL. It even trades blows with Advan BASIC on lots of things.

I recall seeing register and memory info for the video chip used in the original BASIC Engine, but not in the NG iteration. It would be neat to do some scrolling by just hitting a couple of registers. The next thing on my plate for the NG was to learn to use PLOT MAP correctly. I look forward to see what you come up with!
