That's your console port.
It's a BA11-M chassis. I guess the sticker fell off.
You can fire it up and interact with the machine ("ODT"...a sort
of low-level monitor, and the boot ROM at a higher level) but you
won't be able to do much without a drive. Firing it up diskless will
at least verify that the hardware works and that your serial cabling
is correct.
Do you have any DEC RD-series hard drives kicking around? Here
are the "generic" makes and models:
RD50 Seagate ST-506 5MB
RD51 Seagate ST-412 10MB
RD52 Quantum Q540 32MB
RD53 Micropolis 1325 71MB
RD54 Maxtor XT2190 159MB
RD31 Seagate ST225 21MB
RD32 Seagate ST251 42MB
...though you'll only be able to use the later ones if you have an
RQDX3.

Mmm, nice! That's a BA11-M chassis. I really like those...very
compact. The downside is that we'll need to figure out a way to get
a disk subsystem connected to it. Making cables for the RQDX3 was
discussed here in the past day or so...you have an RQDX1, it'll use
the same cable.
Actually, the RQDX1 is kinda crappy. If you shoot me your
shipping address in private mail I'll send you an RQDX3. I have a
metric buttload of them.
That's a
PDP-11/23, not a PDP-11/03. The M8186 is a KDF11
processor module.
In other words: SCORE!
That would explain why I wasn't finding in any of the cards
associated with the 11/03. So this unit was significantly
upgraded in some fashion? That's
an RQDX1 disc controller board. Pretty limited
actually. Was there anything on the other end of the ribbon cable?
The cable terminates in a DB50female connector and the "console"
cable terminates in 4 wires into a bare db25male connector You are
close...we just need to find you some sort of disk
subsystem. What kind of chassis do you have? Look for a number
starting with "BA" (BA11-xx, BA23, etc). Or take a pic and I'll
ID it for you.
I look ed over the entire chassis but could see no BA series
numbers. There are 2 11/03 model numbers in the back (looks like
some sort of upgrade sequence) but nothing BA related. Where would
they be?
