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
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.
