Ron Minnich: Jon Hall used to love telling the story of the VAX backplane with the glue in the board slots, which clever customers managed to damage and have repaired with a non-glued-up backplane. ===== It wasn't exactly a VAX backplane; it was a QBus backplane, though I don't know whether this marketing-induced castration was performed on anywhere but on the backplaces of certain MicroVAX models. I think one of my saved-from-the-dumpster BA23s had one of those backplanes. I just declared it to be a source of spare parts, other than backplanes. Norman Wilson Toronto ON
