That indicates that it's a: GABLES ENGINEERING, MOD. NO. G-1884C

There's a link to Gables products he
http://www.gableseng.com/rotary.asp but I don't see the G-1884C among
them. However, you can request a password he
http://www.gableseng.com/dds.asp to view the on-line documentation for
their products. Surely the eight digits would be explained there.

Also interesting is the 1884C's Volume control!

It's also a control head for a MB receiver.

That control is labelled MARKER, and also selects senstivity.

That would explain 0-9, but these are 0-8.

You've Probably stumbled upon the top secret "Chemtrail" activator. Say
no more about it.

That would be fun just to stick into the empty space on the panel of a
homebuilt.

I find myself holding a 747 transponder control head that I bought on
eBay as a toy for the kids. But, with echos of Spinal Tap's guitarist
in my head, I notice that the selector knobs allow the digits 0 thru 8
to be selected. What gives?

Decade electrical switches are easier/cheaper to procure than octal
switches?

Wouldn't a Decimal switch go 0-9?

Umm... Good point. Oh well....

Perhaps the new New York Airspace Czar has the answer. :-)

I think I have it figured out...

It's actually a USB-connectible transponder for SIMs. In the Sim world, the
kneeboard lists the following emergency squawk codes:

7500 - Hijack
7600 - Lost Comm
7700 - General Emergency
7777 - Military Intercept
8500 - Mom came home
8600 - MP3 player too loud
8700 - Had to pee
8888 - ATF is here doing a drug/alcohol/gun raid.

Here's the answer from a very kind soul at Gables...

The G1884 series started in 1965. I started in this business in
1967. I don't know the whole story but back then ACT control
panels allowed all 8's to be selected. Something to do with a
"remote keyer" function. Apparently this function was never
adopted and later revisions to product and newer part numbers
only allowed 0 thru 7 selections on each digit.

So there you have it! 8888 presumably put the code under remote
control from some other piece of equipment.

What's funny about it?
It's a standard-issue armament panel from a Vietnam era Beech Baron.
You'll find it right next to the ejection seat actuator.

Perhaps 8 is the same as 0 in octal?
