Tim,

No, the DECUS C compiler is a very different kettle of fish.  Sorry to
be so vague - I can only go by memory now as all my archived info is on
CD-ROM's at home.  Back in the mid to late 80's a few folks made available
a bundle put together by the folks at Purdue I think - I believe it was
related to Dr. Comer (sp?) and the Xinu stuff - but this bundle was
intended to provide a compiler environment on SunOS systems of the mid
80's to teach lower level system stuff - I've forgotten if it related
to simulating an 11 or was instead just for a cross-compiler environment
to build Xinu mini-kernels on faster platforms to then download to the LSI
11 testbed.  One place I picked it up (via FTP) called it "sunchip.tar.Z"
or similar, while another I think just called it "chip.tar.Z."

I mentioned you only because I do remember grabbing it from your sunsite
archive while you were still at Caltech and later sending e-mail WRT the
licensing thing.

| Vaguely.  I'll try to track down the exact reference - I'm not
