tape for DECNET-10 seems to exist (at least on trailing-edge). Actually there are no less than TWO DECnet-10 tapes on Trailing Edge, but none of them is really needed. Read my other message to Jordi about that. Anyway here they are: http://pdp-10.trailing-edge.com/tapes/decnet-10_v4_0_sup_bb-x116c-bb.tap.bz2 http://pdp-10.trailing-edge.com/tapes/BB-X116D-BB_1989.tap.bz2 There is also this one that appears to be an interim update between the two above (BB-X116C-BB: Oct-88; BB-X116C-SB: Apr-89, BB-X116D-BB: Jun-89): http://pdp-10.trailing-edge.com/tapes/BB-X116C-SB.tap.bz2 HTH, :) G.
