FWIW, I have two 11/70 machines plus a spare backplane. One of my machines
was a complete original, the other I put together from spare parts. Before
anyone dives into this sort of project, they should fully understand what
they are in for. In order to add the conventional core memory used on an
11/70, there is another set of external boxes required as the 11/70 does
not use the ordinary Unibus memory. Then there is the consideration of power,
front panel, etc.

Still, while I would love to have this set of boards as spares, if they
go for some large price tag and someone needs a backplane for a BIG project,
I would be willing to part with my spare backplane.
