Nor was my answer.
Rather, could the VT14 have been relatively

The VT8-E was a set of modules that turned a PDP-8 into a terminal.
In one mode, it DMA'd a chunk of memory and displayed the contents.
Interesting to fire it off when running memory checks, but that's about
it. It also had a bitmap font generator.
You could run an OS with the VT8-E running, but you couldn't run
anything like OS/8 with the VT8-E as the console as it ate too much
memory and wasn't in any way KL8 compatible.
I don't know anyting about a PDP-14, but it it used a VT8-E, it had to
be an Omnibus machine with Omnibus memory, so it could easily be turned
into a PDP-8/E with the right CPU card set.
