Need a source and info on a memory chip

This is off topic but I know that someone in this list will have the answer. What I need is a surface mount memory chip for a PDA 16mb upgrade of internal memory. The chip in it is an 8 and I've seen a unit with a piggybacked chip on it with a jumper run from the Motorola Dragonball cpu (I basically drew out the mod on a Wendy's napkin it's that simple). Here's what's on the face of the present 8mb chip (the piggy back will be the same or suitable sub): ---------------------------- HYUNDAI GM71VS65163CLT5 0040 AG2 KOREA ---------------------------- It's a surface mount chip that is a 50 pin DIP package (2 rows of 25 pins). I'll need one initially and end up needing around 25 so I might as well get all 25 at one time. Does anyone know where I can get a specs and/or pinout of this and a good source for purchase of small or large quantity? I want the pinouts/specs for curiousity and the source obviously for purchase rreasons. Any help is greatly appreciated.
