SEQ files can be LOADed if you use the filename "FILENAME,S"; for USR
files, you have to use "FILENAME,U"

LOAD works for the region $0400-$CFFF without problems. That is, a file
of approx. 52K is no problem. The LOAD routine just stores into the RAM
under the BASIC ROM in the area $A000-$BFFF.

You can also use the $E000-$FFFF area, as well as parts of lower address
than $0400 - but then, you should know exactly what you are doing.
