Hello,
My layouter uses PADS PCB 3.5. Yeah, it's old and long since out of support but works perfectly, so no need to switch. Unfortunately it needs a dongle of the parallel port kind. He had to replace his computer and bought one with a real parallel port but the dongle won't work anymore. He says the dongle is too slow internally and that this is known as the "pink or green dongle problem". It was discuss in a forum a long time ago but that forum is no longer existing.
He said some environment variable(s) in Windows have to be changed but doesn't remember which ones and to what. Does anyone here remember?
