Have recently an elderly (BJ ~ 2004) Acer TravelMate 4050 get to watch if I still get that up and running New hard disk had to be, I after a long search by store and PC stores ultimately here on Amazon for the lowest 16 (compared Mindfactory 95) and lacked only the memory. Although Komputerbay delivered first derogation to the product memory with ECC, which was not compatible with the notebook, but conversion was straightforward. The second shipment was then correctly and runs great.
