Bliss Compiler wanted

[Kevin Richardson]

Hello,
   Curiosity has gotten the best of me and I've been wondering
whether or not I could recompile some code that I discovered.
The code is written in BLISS (Basic Language for Implementing
System Software), a language developed at Carnegie Mellon in the 
mid to early 1970s. My question is whether or not anyone has or 
knows of the existence of a BLISS compiler for a UNIX System. Any 
referral or response would be appreciated.
