Since you seem to be the ones who "didn't throw that stuff away", like me :-) Thought you might like to look at this: P.R.CRANE is a Computer Demolition Project that creates a PC-Controlled Robot Crane. You can control the crane manually with the arrow keys, have it learn a series of steps, and create and edit a robot control program. P.R.CRANE is made from an old IBM 5152 Graphics Printer, plus about $25 of parts available at the hardware store and Radio Shack You can find this at www.terryking.us (Hit the PARPORT button), and then PRCrane is a one-liner near the top. Somehow I think you'd also have an old DOS machine to run this... If not, there are ways to force XP to let go of it's IO-Priviledge compulsion... Let me know if you get one of these running... I have some photos of kids running these a few years ago. Also: Anyone have an old XT that you want to know what to do with??? I have an idea.
