Wasn't CEJ/MEJ a field-installable ECO? Maybe there's paper on that somewhere. ECS to me would be the real bugger, since it isn't just a box of core sitting off to the side. On the Cybers, didn't it also include the ILR? That was too many years ago. I do remember that it made the business of RCH/DCH much simpler in PPRES--no need to go through MTR. Well, when you're done with the 6600, you can work up a STAR 100 :) I'm not aware of even a software emulator being available for that one. --Chuck
