Lately, my 520ST has been havng problems.  The screen begins to show garbage.
It seems like the memory is being corrupted because the mouse will be going
and the garbage is still on the screen.  What happens is the pixels in the
even columns (of a mono screen) get garbled.  The end result is a screen
of clean columns and dirty columns.  The dirty columns also show 
bands of white and black.  I suspect this is a memory problem because the
garbage shows up on byte boundaries.  Could it be that one bank of SIMMs
is not being refreshed properly?

This is my system:
520ST circa 1986
JRI RAM+ with 2 meg simm (total 2.5 meg)
2 external floppies
1 hard drive w/ ICD controller
1 modem, 1 printer
Spectre GCR

Auto:
Fatspeed
Pinhead
Maccel2
ICDTime (in this order)

Daccs:
Quick ST 1.26
Control Panel/Install Printer

What should I do!!!!
