Forgive me for my iqnorance but I have searched and I'm still not finding the info I need. I bought a PCI parallel port card since my compter's card was disabled in bios. (turns out bios update fixed that) The new card puts out 5V until the onboard card at 3.3V. When I test the pins I get the 5V toggles. I've traced the board down and when I connect the cable to the controller my voltage drops to almost nothing. Is the controller loading the the port down to bad? Is there a way to correct this? I know I've purchased one of the chinese boards off ebay but this is for fun and hobby. I'm trying to do this on a budget. I have electronics experience so I'm not afraid to work on the board and I have access to a surface mount soldering station. Any help is greatly appreciated. I've been at this for weeks. Thanks.
