Needd to know

If I can get an older version of RS5000 what will it work on and what is involved in an upgrade through AB.
This is a previously owned original from AB it still has floppy's so we know it's old.
Thanks In advance

Get with your AB distributor. They can give you pricing on a Tech Support contract which will include upgrades.

Are you trying to verify that your version will support all the Logix processors you have in house? You will have to know the current firmware level of each processor.
