My first job out of college was porting the interpreter from Macintosh Pascal (the predecessor to Lightspeed/THINK Pascal, sold by Apple) from the Macintosh back to the Apple II (as "Apple II Instant Pascal", also sold by Apple). Boy, was that fun. Had to tuck the interpreter into a 4K "fold" of the Apple II memory map -- a block of address space that was normally mapped to ROM could be switched to point to the corresponding RAM in the language card that would otherwise be inaccessible.
[Edit: to be clear, neither of these were the UCSD Pascal referenced in the original article; I had that on my Apple II in college, and demoed a baseball statistics program I wrote in it to the THINK people as part of my job interview.]
