There should be a test program embedded on one of the many Test/Demo
disks floating around on the 'net. Funet will be a good place to
start for manuals, schematics and documentation.

I wouldn't expect so - the memory is paged into one of the expansion
blocks, and BASIC doesn't know anything about it. AFAIK, you had to
write special programs that could take advantage of the memory. Since
it was somewhat difficult to use (compared to writing simple BASIC
programs), and since it was so expensive, they weren't very common.
