[Coco] 512K AND Beyond??? How FAR Beyond???

[rietveld rietveld]

What about programs like Big Basic?  Would that program be able to use more than 512k?

Actually, if you expanded to 1 or 2 megs with a method that used the MMU
registers $FFA0-AF then you could access that memory from BASIC with a
pretty simple patch since the LPEEK, LPOKE, and other commands were
already designed to access up to 512K. Of course the BASIC program
itself is still limited to the area below 32K without major
modifications.  Other relatively simple patches could open up other
possibilities.
