I believe that the IIGS uses $C073, which is the same as the RamWorks
III card, to access banks from ($01 - $7F)($7F being the maximum for 8
MB).  Has anyone tried the Z80+ card with Pascal on a IIe with a
RamWorks III card to see if the entire RAM is recognized?


Also:
A couple of good nibble articles that might help are, in the April
1987 nibble magazine, the Pascal Ram Disk is described in very good
detail and a short driver is also included but only accesses the Aux
memory.  But it can be easily rewritten to use the memory above 128k
by following the RAMDisk 3.3 article in the April 1990 nibble
magazine.

RAMDisk 3.3 uses the "mvn" command to move memory to any available
page up to the limits of memory.  The Pascal RAMDisk article shows
which bytes of the RAMDisk are used to display the size of the
RAMDisk, which will need to be adjusted, and also how to create the
RAMDisk.

The articles are for Pascal 1.2 or 1.3 and also requires the Attach
Tools disk from the Pascal Device Support Tools series.

Hopefully this info is of use to this topic.
