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 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
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
