[SCC_Active_Members] Agenda for 8/25/04 SCC

[Gio Wiederhold]

Paul,
   I'd love to have the $tudent compiler material scanned in.
Tell me what's the best way to get it to you,

I recall that the prefix $ indicated an operating system command to
the 7090 operating system.

I also had the following discussion with Dave Redell.
Professor Austin Hoggatt was the director of the Computer Center then,
He was succeeded early 1965 by Prof. Abraham Taub, since deceased.
We might still contact prof Hoggatt:

Hi Gio,

I'm not at all sure what you are referring to here. The $TUDENT
compiler
ran on the 6400, so none of the above description seems to apply. It
sounds like you may be referring to the funny dual-core 7094 that sort
of arrived but wasn't actually put in service and ended up at LBL. The
dual 6400s had 64K and 32K (x60bits) respectively, but it doesn't
sound like that's what you're talking about either. As far as the
front
end processor for the 7094 DCS was concerned, that was a 7040. The
1401 was gone years before the $TUDENT compiler appeared on the scene.

Am I somehow misreading your email?

Dave,
   It may well be that the $tudent compiler was moved to the CDC 6400.
I am quite sure that the dual core 7090 (then) was initally installed
in  Campbell Hall.  Correspondence in my documentation is from 1962
and mentions the 7090.
I went in 1964 from UC Berkeley to ITT Kanpur, and lost contact then.

   The person who wrote the compiler originally was Gary Breitbard.
Another participant was Gerald Miller. I am still on contact with
Miller (now Joaquin Miller), who now lives in Berkeley. Gary
Breitbard lives in Palo Alto.  They might know soome others. Ken
Thompson (of UNIX fame) was also around at that time. They may have
links to others of that time. Another name is Jerry Johnson, who
followed me a year later to IIT Kanpur and now also lives in Oakland.

   If it's worthwhile it may be nice to organize a meeting at the
museum to get a good timeline on this piece of history orally from the
survivors.  Maybe you can bring it up at a museum software meeting.

   I am quite busy with some crtitical high-leverage consulting, but
would be willing to devote a day or so to that piece of history.

Thanks for the followup.

Gio
