Wouldn't life be wonderful if IBM had forseen the possibility of using 256kbit chips in the AT. No, you cannot replace any or all of the chips in the AT with 256kbit chips, at least not easily. About the only thing that I can recommend is going to a true-blue dealer and seeing if you can buy a piggyback from them. They'll want to service it themselves but you may be able to convince them that you're not an idiot and can actually handle the terribly technical task of pulling a chip out and pushing in another. Good luck, jim frost madd@bu-it.bu.edu
