Joe:
I did install the memory upgrade my self. It's just unscrewing the cover
and a circuit board. Then just plug it in on the pins. No switches to
set.
I can't remember where I got it, but it was a 2 mb board (incase I ever
want to use fonts). You may want to see the difference between 1 & 2 mb
prices. If they have 2 mb boards with only 1 mb on it, sometimes it's
cheaper just to buy your onw chips.
