Who wrote
Amiga-OS?
IIRC it was based on Tripos, which came from Dr Martin Richards at
Cambridge University... I really must get Tripos running on one of my
PDP11s sometime....
You are correct. Dr Richards ported Tripos into a machine-independent
BCPL representation called Cintpos. It will run on most systems, including
x86 and PowerPC.
Tripos was also written in BCPL, or at least much of it was. I have the
sources, and the sources for the BCPL compiler (and guess what that's
written in...) As I said, one day I must get it running on the PDP11
again (which is one of the machines it originally ran on).
I think you misunderstand me. The special bit about Cintpos isn't that it's
BCPL, it's that the BCPL compilers he maintains compile to a bytecode and
this is machine-independent.
