Well, this PDP-11/24 I picked up yesterday doesn't appear to want to boot.
All boards appear to be present (at least, going by the table under the lid)
and in good shape physically.
When I turn the keyswitch to 'LOCAL', the 'DC ON' light comes on and the
'RUN' light comes on for about 1/2 second. When I push the 'control'
switch
to 'BOOT', the Run light comes on or about 1/2 second, then goes out.
Looking inside, there are three lights on the M7133 cpu board, labeled '0',
'1', and 'CLK'. The '0' and '1' lights are on
continuously, the 'CLK' light
only comes on for the 1/2 second after power on, and while the 'control'
switch is held in 'BOOT'.
As usual, I have absolutely zero docs on this system, so any help would be
appreciated.
