Another parallel port page


Si Ballenger

Jan 1, 1970
I've been doing some tinkering with the parallel port and have
made yet another parallel port page that might be of interest to
those that want a very simple computer controlled setup. My local
Radio Shack stores still carry the 74HCT259 chips (276-2868,
$1.29), so this little project can be made from what is still
available at the Radio Shack stores. Pushing things to the max, I
think you can seperately control up to 120 lines from the 8
parallel port data pins. Using the Apache (or a variant) web
server or possibly the AnalogX SimpleServer (It should work), one
can setup simple web control of devices connected to the
computer. Not real high tech, but this might be of interest to
the beginning tinker types or the kids for a simple computer
control project. Programming is super simple too. As usual YMMV!
