I couldn't say for sure. I have seen conflicting information in sources
dating from the 70s when the TV-11 and XGP-11 were very much in use.
For several reasons, I believe the TV-11 was the first machine attached
to the 10-11 interface, and the XGP-11 came second. This would lend
some weak support for the theory that the first would be a 11/20 and the
second a 11/10.

Replacing or changing machines around would explain the confusion, but I
haven't seen anyone remembering such events, or any written record to
support that.

I did bring it up with TK at some point. He said the TV-11 must have
been a 11/20, because at the time there was no other PDP-11 model
available. But as far as I can see from file timestamps, the AI lab TV
project was started in 1973 or so when the 11/10 would have been
shipped.
