Regarding a memory upgrade for a Mega 2ST..

Kenneth, if your Mega 2 is one of the early ones, before Atari
"redesigned" the motherboard, upgrading the memory is a relatively
straightforward process, although one that requires some 
technical expertise.

Essentially Atari used the same motherboard for both them Mega 2 and 4,
simply leaving out half the RAM chips for the Mega 2.  There are holes
where the second half of the RAM can be installed.. the only problem is
that they are all soldered shut during the manufacturing process.

The upgrade consists of unsoldering the holes, installing sockets and
bypass capacitors (and one Mega2 that I saw already had the extra
capacitors installed), and plugging in the RAM chips.  Then three
resistors have to be added, and you'll have a Mega 4.

The costs involved are the RAM chips themselves and the time needed.
Depending on who you get to do the job, it should cost considerably
less than $100.

Also, since the chips are mounted directly to the motherboard, you're
likely to find it to be more reliable than any "solderless" upgrade.

If there's anyone near you who can perform the technical work, this
would be an ideal thing to do for your Mega..

(You'll probably have enough of your $100 left to get Warp-9 too..!)
