It also contained the Apollo Ring network card to hook up to the network. It may or may not have an extra memory card. It did not have the display card as it was a rack mount server. It also had a Multibus 1 cardcage which held a SMD controller, a tape drive controller or any other Multibus card to drive interface one wanted to hang on the ring. It commonly had CDC 9" hard drives but you could use 8" or 14" SMD drives. Apollo also hung Cipher tape drives on it also. You could put removable pack drives also. It was used as a Server on an Apollo Ring. It did data and program storage mainly. If someone was going to set up an Apollo Ring for a museum it would be great. As to what Jim could use it for I'm not sure. Prob. trading material as I am not sure the Computer Garage has the space for an Apollo exhibit. If someone is interested in Apollo I have a working 580 system that I would like to sell or pass on. Paxton
