Joe R. was asking about Matrix cards We used to have a VME based x-ray film scanner that was a Matrix product, it was a prototype. If I remember correctly I think Matrix was based in California and made film cameras and scanners for industrial applications. Our initial unit had a VME controller with a micro PDP-11 as the network interface. I think I have the micro PDP-11 somewhere in my garage. Looks like Agfa purchased them. Mike
