OK, now I realize what people are saying -- the menus in UCSD Pascal were not "drop-down." Sorry, I'm so used to letting the term trip from my fingers that I mistyped. Yes, they were single letter menu commands on a character-based "graphic" screen. They did influence the development of drop-down menus at Apple. - Bill On Fri, Aug 17, 2012 at 1:12 AM, Ian S.

I have 8" floppy media for UCSD Pascal that runs on my MINC-11; I have not attempted to run it on other PDP-11s yet. It behaves as Al describes. -- Ian

UCSD Pascal, BTW, likely embodies the first use of such features as drop-down menus and had a large influence on Apple, which distributed UCSD Pascal as Apple Pascal. Apple employed many of Bowles's students.
The original UCSD Pascal Environment which ran on the Terak is text-based. You are presented with a list of modes on the top line of the display and type a letter to drop down a level in the hierarchy. This same interface was used for the Lisa Pascal Workshop, which is built on top of SVS Pascal, a 68000 native Pascal compiler, instead of the P-Code interpreted UCSD system. The original Macintosh applications were built in the Pascal Workshop environment with Macintosh toolbox library extensions until the native tool chain was available.
The most known Apple employee that came from the UCSD group is Bill Atkinson. Al Hoffman was another, who supported MPW Pascal compiler.
