Two years ago, I made a cross-country trip, and one of the stops was to one of the last people who was doing third party service on 19xx's in Louisville. I took all of the maint docs, some of the packs and all of the boards from a 19xx because they were cleaning out a storage unit. I had several more stops to make, and had no room for the complete 1900 that he had. The 1900 CHM has came from a hospital in Kentucky and was picked up by someone who was interested in the machine and drove there and back to pick it up. Aren't these rebadged Convergent NGENs ? Marvin Johnson has a bunch of docs on these. I didn't realize how sophisticated the OS was on these, probably should see about getting the docs scanned, if he still has the stuff.
