Thanks for the information however thats not really what I'm after. Ebay is of no use when looking for the proper hardrive for Sony vaio PCG-505TS and it's of less use when looking for the proper memory I need to install. I see where the memory go's but it has been so long since I cracked open a laptop this old it's alien to me all i see is 2 open slots less than 1" long and they don't seem like the standard slots which is why my question on memory i know I need 128mb which is the max, the system has build on 64mb of memory. I have a picture I'd be glad to email to anyone that can guide me in the right direction where i get this memory. Sony is of no help.
