Probably, the panel with the lights should be universal, it's only the
printing on the plastic which defines which light represent what it
means.
Yes. The lights panel has 144 lamps on it. There are 4 ribbon cables
ending in single-height DEC connector boards, so all the contacts on said
boards are signals. The groudn return is via the power wiring (!). IIRC
it needs 8V, whihc a lot of older DEC PSUs provided.
There are 4 otherwise unused connecotrs in the RK11-C which I am pretty
sure are used for such a lights panel. Sometime I must try it.
Of coruse the printing on the plastic front panel is device-specific.
