The Famous 70s Era Apple Pascal Poster [pdf]

From the Internet Archive comes a PDF of a poster that was popular among my friends group in the late 70s. Most of the crew I ran with had experienced "more advanced" languages than the BASIC that was common as the default on microcomputers of the day. Pascal was definitely a popular option and this poster was just darn beautiful in that 70s sort of way.

And here's the main link for the poster with metadata and a few download options: https://archive.org/details/pascal-poster-v-3-a-1

I first learned programming on a Wang 2200 computer in 1978, which used the Wang BASIC dialect. Wang BASIC was both very primitive (single letter or letter+number names, no local scope, fixed width strings) and very powerful (built array operations, including MAT SORT).

A year or two later I got a book from the library on PASCAL. I recall skimming through it at first and thinking: is this real code or pseudocode? I couldn't believe, eg, that one could test for set inclusion with a built-in primitive.

If it was from 1979, does that mean it is this one for the Apple II: https://en.wikipedia.org/wiki/Apple_Pascal

It was based on USCD Pascal, which compiled to p-code. It required 64kB of RAM and was bundled with the Apple II Language Card, which had 16kB of RAM [1]. The card cost $495 initially, which is about $2,200 in today's money. [2] It didn't fit on one floppy, so required some disk swapping.

Very nice.

Ah, the "train track" diagrams. I saw them in a book, not on a poster, but it blew me away that all the language was just right there.

One thing, though: I seem to remember there being more diagrams than that. Is my memory failing, or is this poster not the whole syntax?

Just finished a losing battle with C++ grammar. I'm envious. :-(
