LCM+L owned a real Honeywell 6180 front panel.
Stephen Jones owns the panel; it was on display at the LCM as a loan.
The folks in their lab interfaced it to a microcontroller (I think it was
an RP3 or 4, but it could be something like a
BeagleBone, I never knew).
The LCM built a FPGA board to interface the hundreds of little unlabeled
white wires on the panel to a RS-232 serial line.
The simulator runs on an Intel NUC, and interfaces with the panel through
an USB RS-232 dongle.
It was running Multics Release 12.8 on a SimH-derived Honeywell 6180 [I'm
not sure if those changes ever made it back to
OpenSIMH - I have not
personally tried it myself].
SIMH based initially, but SIMH was unable to support the needed
functionality and has been mostly replaced and the kept bits heavily
modified; trying to merge those changes into OpenSIMH would break every
other simulated system.
This system seems to have been moved to SDF's new
site.
Yes; I went and visited it last weekend.
