HP-2116A chassis (or repairing cast aluminum)

[Bob Shannon]

On HP 2116A's and 2116B's, the core stacks are not mounted on cards
(the 2116C uses the same style of core memory as does the 2100A/S).

There should be one or two large blocks about five inches on a side, and 
perhaps
four inches thick.  Each block should have a set of five or six cables with 
hooded
edge-card connections that connect to the drivers and sense amplifier boards
in the top row of the chassis.

The center row is the actual CPU logic, and is normally only half-populated.

The bottom row is the I/O backplane and only 2 or 3 boards in that row 
belong
to the CPU itself, the rest (16?) are for I/O cards.  Many of the same I/O 
cards
used in the 21MX class machines will work in the 2116.
