Was there ever an indicator panel for the RC11? .. I have a set of RC11
modules .. No backplane though. I've not found any docs for these, I suppose
they're probably on bitsavers and have overlooked them.
Looking at the manual
and engineering drawings (at BitSavers, as you guessed), no lights.
I've added links to those to the CHWiki RC11 page:
https://gunkies.org/wiki/RC11_disk_controller
The engineering drawings have the wirelist for the backplane, so it would be
possible to wire a new one. (I'm in the process of doing that for my KE11-A.)
Not sure it would be much use without an RS64 drive, though.

One could perhaps emulate the RS64 data stream using a fast-enough micro, ala the MFM
emulator.
Quite easily, I'm sure. The RC11 runs at a word per 16 microseconds, a megabit per
second. The RF11 transfer rate is the same. So either one could easily be emulated: a $4
Raspberry Pico is more than enough for the task (the BeagleBone of the MFM emulator would
be massive overkill).
