What is the provenance / source of the panels?

Mine came from an acquisition by Nick Allen from a collection in 
Georgia.  I believe there was a Multics installation in Atlanta they 
were removed from.

The panels on the 6180 at USL were all inside side access panels for one 
of the rows of hardware boxes. One box panel was usually exposed with 
the door removed, but it could be closed up.  There were problems which 
required access to one of the panels frequently in operations, so it was 
seldom closed.

We probably could get access to Dockmaster with some advance arrangement 
and good will on the part of the CHM when they have time to arrange 
access to the storage to which  it was moved to see actual installed 

I agree, the black panel has about the only interesting display.

I might also suggest that once David Griffith finishes porting the PDP 
10 Panda panel and has that design working and integrated that there may 
be enough blink'n lights there to display a satisfying 6180 display on a 
normal desktop case.

the advantage is that it is at least already 36 bits and has some of the 
nonsense of having that bit count worked out already.  I'd think we 
(someone) could fork and add a second bank of lights, or use two of the 
Panda usb devices to put out a lot of information about a 72 bit 6180.

His main problem now is with interfacing and coding PDP 10 assembly code 
which is obviously not useful for re-purposing it for Multics use 
anyway, and is internal to SIMh PDP10 emulation.

If a lot of people who are interested in blinking Multics Honeywell 6180 
displays were interested it would contribute a lot to him selling out a 
run of his board kits.
