I have had a response to my request to find a Laser PC-4 Notebook computer from someone here, but they referred me to a reseller that has modified it by adding a larger screen and more memory, which is fine, except now it doesn't have software for appointments and a clock calendar, I don't believe. They call it a Laser PC-5. Does anyone know where I could find a real PC-4 as sold several years ago? I would be interested in a used one. Respond here or at : rotation(a)juno.com
