(I've got one I could sell, if anyone's interested..) Going to 48K is a little more complicated because there aren't enough address lines on the RAM card socket... the 48K card I installed in my 400 required soldering a little template pc board onto the bottom of the motherboard. It gets the missing address lines from the cartridge socket... installation was quick and painless... (I'd sell the 48K memory board too, but I'd have to see about removing it and the template from the motherboard) BobR
