[Coco] RAM expansion options for the CoCo 3

[Sean]

Sorry to bump a 6 day old reply, but I remember an ad and also a booth at a
Rainbowfest advertising "Big Basic", that could take more advantage of more
available RAM.  I don't remember any specifications other than being
interested in it at the time, but seeing this thread rang a bell.
