Hi -
I saw the note about upgrading a 520 to 2.5Mb when it already has an extra
.5Mb added.
Well... I am a friend of the guy who has the Atari shop in town, and I do
the tricky business there. I have spent a few hours on 3-4 machines of that
kind, to manually solder in 2 1Mx8 SIMMs in 520s with junk on top of the old
chips. Put the CAS of those pigs to +5V, and then testing. No customer has
come back with complaints. Just glue the SIMMs with silicon glue somewhere
in the box.
