There was the PDT-11/150, which had a free-standing unit with two 8" floppy drives and a number of serial (synch/asynch) and parallel ports. The PDT-11/130 was built into a VT100 case (essentially) with two TU58s as the system devices. The PDT-11/110 was also in a VT100 case, but had no storage. It was supposed to be down-loaded with the same protocol as the GT40 used when being downloaded from a -10. The chipset consisted of 4 chips, but there was an option which replaced the 3007/3010 microms with a single dual microm, which freed space for installation of the EIS/FIS chip (I know, I've done the modification to several PDT-11/150s). RT-11 ran on both the 11/130 and 11/150, using the same PD device handler. In fact, the rom code on the 11/130 and 11/150 knew about RT-11 Qelements, and all the handler had to do was pass the Qelement structure to the rom code for it to do the processing.

I >>thought that the 11/10 was that unit. Oh yes, there was also the VT103, which was a VT100 with a more gutsy power supply and a Q/Q backplane. I had one of these in my office when I used to do RT-11 Development (system device was a DSD880... I still have them). Since the backplane was Q/Q, you could install any of the Qbus CPUs which would run in a Q/Q backplane. I'll have to pull out the system to check, but I think I had a KDJ11-A in it when I moth-balled it...
