Modicon PC0085

I need to replace a Relay card or rewrite the logic on a new PLC. Can anyone suggest a contact person or let me know what I need (cable & software) to download the logic from this old thing?

What is the number on the card? I may have a replacement or possibly I can repair the one that you have. The software is an old DOS based program which is pretty simple. The unit originnally programmed in boolean via a small snap on panel. Modicon later added this DOS software to make the program appear in ladder logic and allow the user to up/download the program. The kicker is that cable has a built in dongle that is keyed to the software. I have both. I realy don't want to get rid of either though. These units are/have been pretty reliable. Modicon added them to their line in the early 80's to compete with the other manufacturers low cost units. Let me know how I can help.
