Doug Gwyn made MAJOR contributions to the VT11/VS60 simulation.
It also has "Type 30" support for the PDP-1.
I started (but never finished) "Type 340" support.

Someone was looking at (re)integrating it with modern SIMH.  I'd
encourage anyone who works on this to use some modern display layer
(e.g. SDL), rather than the primative adaptation layer(s) I wrote.

is a checkout of the "latest" files from my CVS repository.

There is also http://www.ultimate.com/phil/xy/kit2.zip
(dated Feb 2004) which includes SIMH from back in the day.
