| The AI lab PDP-10 had a "10-11" interface with up to eight Unibuses. Each Unibus is mapped into PDP-10 memory and can be used to attach a PDP-11. Or other Unibus processors like the CONS Lisp machine, or the CHEOPS chess accelerator. The TV-11 was a PDP-11/20 attached to 10-11 Unibus number 0, suggesting it was the first to use this facility. It was shortly followed by the XGP-11, an PDP-11/10 driving the XGP printer. The TV-11 has bitmapped framebuffers, a video switch, and a keyboard scanner. It was used for raster display workstations around Tech Square. | The AI lab PDP-10 had a "10-11" interface with up to eight Unibuses.

| There is a software emulator for the TV-11 and its Knight TV and keyboard hardware, called tv11 and tvcon. The tv11 talks to the PDP-10 emulator through TCP/IP; this provides the 10-11 interface. When ITS has booted, the TV-11 software must be loaded. This is done by running //:STUFF TV//. If the 10-11 interface works, the software will be written to the PDP-11/20 core memory. Next, ITS must be told to reinitialize its communication with the TV-11. This is done by depositing 1 to ITS location TT11P. STUFF and TT11P are normally automatically handled by the program CHANNA; RAKASH TVFIX. | There is a software emulator for the TV-11 and its Knight TV and keyboard hardware, called tv11 and tvcon.
