Is the NVRAM battery still in place in the console bulkhead panel? Those

first guess would be battery corrosion on the bulkhead panel is causing the
problem if it happens with multiple CPU boards.
I have a BA23 VAX of unknown provenance, which
tonight I moved from the
project backlog to the workbench. It comes up and passes
selftest. But any
key I press on the console terminal is repeated a couple dozen times (to
the limit of the input line length?). This makes it impossible to interact
with ODT.
If I install a spare KA630-A and 8 MB memory board, I get a similar fault
where chevrons repeat to infinity. This seems to suggest it's a fault
between the CPU and my terminal. Can this be the result of a bulkhead or
other cable problem?
