VAX ODT console fault

[r.stricklin]

Folks;

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.

Is this a normal sort of well-understood failure mode? In this session excerpt, the only thing I am sending is <BREAK> (giving me the normal chevron prompt), <ENTER> (giving me the repeated chevrons, sometimes with other characters in the pattern), ?, and h. I did not type any colons at the [XQA0] prompt, though I did try to backspace them. The behavior is the same if I remove all boards besides the KA655-B and 16 MB memory board.
