Nope.  That's what mine looks like.  His has some weird spot-welded bracket,
presumably an earlier design.

Onderwerp: DEC BA11-K KY11-L mounting brackets -- how?

Hi all,

I'm reassembling an PDP-11/34 in a BA11-K chassis right now, and am a little
puzzled by the front mounting brackets (the ones that hold a KY11-L of
either sort on the bottom, and a half trim-panel on the top).  In
particular, on the bottom half, the available place for screws to go to
attach the bracket to the chassis is nearly completely blinded by an
overhanging tab.

The engineering drawings I've seen are unfortunately not very clear on
this...  Anybody have an 11/34 in a BA11-K and care to take a peek and tell
me how the hardware here is properly configured? (Hex head instead of DEC's
ubiquitous Phillips truss, to allow tightening from the side?  Machine screw
from back, and a nut on the front?  Other?)

    cheers,
      --FritzM.
