U of O also had FOCAL running on it, which may have been a local port

Yes, thanks for the correction - a slip of the virtual tongue. I
didn't realize the Bell Labs machine was so basic - in fact, it was
my understanding that the basic machine was 8Kwords. The machine at
LCM actually has 16K, with a DEC field mod to allow it to be
addressed in PDP-9/15 fashion.

OK, we're good then. :-) I have a soft spot for the 12-bit
machines, if it doesn't show. -- Ian
