FWIW I'm developing "tiny-titan", a stand-in for Cambridge's Titan mainframe that talks to Heinz Lemke's 1972 PIXIE program over an emulated version of Neil Wiseman's PDP-7 <=> Titan link. It doesn't emulate Titan itself, just the conversation PIXIE had with it, so the unmodified 1972 PDP-7 code dials home and uploads its drawings.

>Titan was the prototype of the Atlas 2 computer developed by Ferranti and the University of Cambridge Mathematical Laboratory in Cambridge, England. It was designed starting in 1963, and in operation from 1964 to 1973.

Here is a photo of Heinz Lemke operating PIXIE with the light pen and 340 display on the PDP-7 (also seen in the video above):

Ostensibly the site is about HyperTIES itself, but I'm publishing other stuff there too like a PDP-7 emulator!

Here's a part of the demo I was giving at EduCom in October 1988 at the Sun booth on the trade show floor, across from the NeXT booth, where Steve Jobs and Bill Joy came by. Because he had shaved his beard, I didn't realize it was Bill Joy when I was showing him a demo of his head popping up! He took it pretty well though, better than Jobs.

Here's a paper looking back at HyperTIES:
as far as i know the control plane on their equipment is still a pdp-10 compatible
