There were several editions. My copy (sitting on my bookshelf as I speak) was the '73 edition (though I think a later printing), but they did revise it including releasing it for the then prevalent home microcomputers.

I first learned programming converting these things to run on my VIC-20 (and later C64). That earliest effort was prior to those later editions... and I'm kinda glad... I had to learn what different things actually meant and judge what was important and not.
