I have a Commadore Amiga, 64, 128. But i doubt that they are worth anything. I also have an old IBM portable personal computer that is the size of a suitcase. It has a detachable keyboard, green monitor, and two 5 1/2 floppy drives. I doubt any of these are worth anything but i once heard that if you had an apple mac or lisa they were worth money. Is this true?
