It was for either the Z80 apu running CP/M making its a terminal/media
thing rather than new version.

Decmate II/III uses 6120 (PDP-8 with EMA).  There is no *nix for the PDP-8
and OS278 is common.  FYI: VMS runs on VAX(32bit) and Alpha(64bit).

If you can fit the game format into a 32Kword 12bit machine it's possible.
Generally speaking there isn't a C compiler for PDP-8 I know of and the
4k paged addressing and very minimalist instruction set would be an 
interesting challenge. I've seen Fortan, Focal, Basic and even algol
on an 8 but never C.


There is also the VAXmate, a flavor of a 286 clone.
