Those are the RAM locations to which the OS copies large and small font character bitmaps, respectively, in preparation for them to be drawn.

Bcalls seem to change $83EB on the 84+ calculator, however changing it doesn't do anything bad.

Should we maybe make this table some seperate page or somethinga nd keep it up-to-date with new information?

It seems that only happens for app bcalls (an app calling to its other pages), but I've added the information to the table in the first post.

So I took this table and parsed it with regex into some php-usable data. You can see the result here: https://www.omnimaga.org/index.php?page=ram
it's not only finally looking like an actual table, but at the top box you can just enter any address or label and you'll jump to it.

Entering address as HEX:
 - just typing hex
 - or prefix with $
 - or prefix with 0x

Entering address as BIN:
 - prefix with %
 - or prefix with 0b

Everything else will be treated as a label, the first match will be used (case-insensitive). (e.g. "edit" will jump to smallEditCol ($8177))

If that exact address isn't present it'll jump to whatever row contains it
