8Leds

Do you remember the good old days while sitting in front of your Commodore 64, fumbling around with the user port, trying to get some selfmade add-on to work?
Why stop having fun when you can have it with you PC as well?
8Leds makes use of the inpout.dll provided by logix4u.
It controls the LEDs on a little circuit attached to the lpt1 of your PC and displays them at the same time on the screen.
The patterns can be edited with a normal text editor in the file 8leds.pat.
 

Prerequisites:
If you only want to run this program on the screen nothing else is needed. If you really want to control real LEDS you need to download the inpout.dll from logix4u and place it in the same folder. Finally you would need a soldering iron and a little execise to put the circuit together without burning your fingers :)

Disclaimer:
I can not be held resonsible if you manage to fry your parallel port! Use a cheap Lpt card instead of the mainboard for testing.
