That’s interesting — that wasn’t apparent from the parts of the manul I
glanced over.  (I hope that doesn’t sound like I doubt you!)  The HP
3000 didn’t do memory security the way the B5000/B5500 did, did it?
With segment descriptors granting fine-grained access to memory, like
CHERI today?  I had the impression that it was a relatively conventional
16-bit mini except for having an instruction set that was a more
convenient compile target — more like the HP 9825 than like the
Burroughs 5500.

What did SPL do to expose the hardware that C doesn’t do?  That’s
exactly the kind of insight I was hoping for when I saw your post!  It’s
difficult to extract such informtion from language manuals.
