[Coco] Programs larger than 32K?

[Robert Gault]

Don't know the name of those programs but take a look at the specs for the SN74LS783 (SAM) chip.
You will see that in addition to all RAM and RAM/ROM ($FFDF/$FFDE) you can page switch. With 64k RAM 
installed, writing to $FFD4 gives (page0) normal 32k RAM, but writing to $FFD5 (page1) and your 
unused 32k is active. Since page switching leaves the ROM present, you might be able to have Basic 
programs switch pages and in effect use 64k of RAM.
