Yes, it does... same ole' qbus...

You'll need processor (M7270), memory (M8044), serial line card
(dlv11-J, M8043), boot/terminator (BDV11, REV11, etc), disk
interface card, disk, terminal. Of that list, I think you'll need a
BDV11 or REV11, unless the disk controller you have has on-board
boot (which the DSD880 controllers do have).

If I remember correctly, RT-11 originally booted in as little as
8kb of memory. Later we had to increase the minimum to 12 or 16 kb.

I wish I'd known earlier... I have a couple of pdp-11/05,10 chassis
which I am giving to a group in Rhode Island...
