The company I work for owned to C3B computers. Each was a 3 user system with 80 Meg hardrives. One system was older and used less reliable boards. The newer had many less problems. Over time the two systems became one 5 user unit with 2 80 Meg hard drives. We ran that computer non stop 24 7 for serveral years after the OSI company was gone. All the boards had tin plate sockets and were fine as long as the unit remained running. If you had to power down for some reason, you had to open the unit up and remove all the chips from their boards. Clean and reseat them. Over the many years that I operated this computer I had changed out most of the sockets and connectors on the back plane with gold plated parts. When the computer was finally shut off for the last time it was a very reliable unit. Kind of sad tosee it gone. I wish I could find one.
