  I've recently upgraded my 520 ST to 2.5 megs with an EZ-RAM board and I've
had a few problems. The first 2 megs of memory (from address $0000 to $200000)
is fine, but I have problems with the 512 K bank at the end
of memory($20000-$27FFFF). When I do word-length or long-length reads from this
area, I sometimes get the wrong value back. With byte reads, this almost never
happens. Secondly, only the lower half of a word gets munged up on the read.
Has anyone else had problems like these and does anyone have a solution?
