I currently have a standard 520ST that I
would like to upgrade to 2.5 Meg (I already 
have the 16 1 Meg chips).

Could someone please summarize the hardware
changes required to convert a stock 520ST to
2.5 Meg?  I have build hardware projects before
and would rather do the modifications myself.
Besides, the RAM chips I have are surface mount,
not DIP, so they wont work with any of the RAM
boards that I know of.

Thanks in advance,

dan k.
