If I found the right place, it says 376, 308 KB ram. When we got the Amaya and the original programs for design shop, etc. a tech at Melco said our system was good enough to run both. Nothing else is run on them-everything else stripped out. Not even a printer or scanner hooked up. Ever since the upgrade was installed this summer we get repeated 'low memory' errors and problems running it. Have reloaded the programs several times, and defragged the computer twice. Upgrade to a second computer was planned to run Designshop on a separate system, but since we were convinced not to buy another Amaya I'm not going to bother. Decided instead to spend 3 times as much to get a digital printer/plotter. Once we get it here we might put in a larger (ram) computer with newer processor for the Amaya but we'll wait and see. Using this one just to proof designs and do small retail orders-anything that is a quantity gets farmed out after we proof it.
