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
panels.
I agree, the black panel has about the only interesting display.
+David Griffith
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.
thanks

they look like something too complex to let operations level

but are these used with exactly WHICH Honeywell system? If we
are going to display them need to tell the right story in the museum.

The panels would be pretty much un-used Unlike 360 panels these
were hidden behind doors for most of the time. Assuming the work
the same on a Multics box as on a regular L66/DPS box the only
time they were really used was if you split a 2 x CPU system into
2 x 1 CPU system, or changed the memory configuration from
interleaved to non-interleaved. Pretty sure you could IPL from the
console.

*Subject:* Honneywell multics? from panels. the inline phots in
this message folks -smecc
ok sent to all the people cc on the multics stuff.. will not go
though on main listserv probably
here are some of the panels think there is more there are at
least 2 of each type
one set will make display her at smecc museum in az the other
set??? maybe someone want to wire into an emulator <<<grin!>>>
aside from a little dust and bad lighting these things look
like they were pretty unused thanks ed# www.smecc.org
