Martin Richards provides a current implementation of the Tripos
environment that runs as an interpreted guest (under Linux or
whatever). It is called "Cintpos" and is available at:
http://www.cl.cam.ac.uk/~mr10/Cintpos.html
Cintpos is implemented in BCPL:

These and other interesting artifacts are at Dr Richards' home
