This is not a solution to the >512K RAM problem, but it will (I hope)
give a credible reason for the problem of certain programs claiming
that the PC is "out of memory" when more than 512K is installed.  If
you look at the DIP switch settings for specifying installed RAM size,
you will notice that the first four switch settings for 64K and 576K
are identical.  Ditto for the settings for 128K and 640K.  The fifth
switch is the determining factor here.  If the program you use only
"looks at" the first four switch settings to check RAM size, it will
"think" that only 64K or 128K is there (for 576K and 640K respectively).
While patching the program is the optimum solution, this is often not
possible.  In this case, you may simply want to reset your RAM size
selector to 512K and hope that your RAMdisk and RAMspooling programs
are able to recognize the memory above it anyway (AST software can
do this).
