 ; RAMTOP to $6A00, disables BASIC (on XL/XE), disables ANTIC DMA, then

-; This is pretty weird: when loading fnchat.xex from MyDOS 4.50 or
-; (apparently) Spartados X, a 0 byte gets written to our display
-; list. It's up in the $BFxx area, which is to say, where the GR.0
-; screen used by DOS lives... and somehow these DOSes are writing a
-; 0 byte to the screen (a space) in the middle of loading the file.
-; Setting SAVMSC to something else ($0600, here) avoids this.
