I think you'd want a BA-11N to stick an RLV11 in there. I'm
reasonably certain, from the top of my head, that a BA-11N has CD
slots and the BA-11M does not, but I could easily be misremembering.
My first -11 hard drive controller was an RLV11 that ran me about
$100. I dropped into a BA-11N w/KDF11, DLV11J, MSV11-mumble (M8044),
and LPV11 that all ran me $300 in 1986. I borrowed a VT220, an RL01,
and an LA180 from my main PDP-8/a, I made a living on that -11 for
almost two years. I still have it in a slightly improved form (I
upgraded the backplane to 22-bit and threw more memory into it). I
ran RT-11 v5.something on it for years (5.3?) Very nice system, but
so is the OP's 11/03 w/floppy.
RT-11 works fine on a floppy-only system. It works *great* on a
hard-disk system. It was one of my favorite environments before I
managed to scrape together my first UNIX system a few years later.
