Anyone have a spare PDP-11/84 serial console panel they could part with?

I am probably wrong, but the part number on the cabinet kit for the
serial port with the 25-pin D-shell connector for the PDP-11/83
that I have is 54-16023.  About 1/2" to the right is a second
number 54-16022-01C1.  These numbers are on the solder side
of the PCB board.  Also stamped on this board in ink is the number
7021150-02-Rev A1.  In addition, there are TWO ribbon cables
which connect to the quad board, a 20-pin cable  AND a 10-pin
cable.  I may have another cabinet kit somewhere that looks the
same at first glance, but has different part numbers.  If I find it,
I will reply with those numbers.

As far as I can remember, all of the quad PDP-11/73 and PDP-11/83
CPU boards use the same cabinet kit since the only differences between
the two boards is the J11 chip version and the clock crystal which
supports running the PDP-11/83 board at 18 GHz rather than 15 GHz
for the PDP-11/73 with an older version of the J11 chip that had a
problem with floating point when run at the higher speed.

Finally, since the quad CPU board for the PDP-11/83 is the identical
board used in the PDP-11/84, I would expect that the same cabinet
kit would be used for both systems, but naturally I could be wrong.

If you can't find a cabinet kit somewhere, let ne know in a few weeks
and I will look to see if I can find the second one.  I am in Toronto,
so shipping would be much more expensive outside the USA.
