Many of the articles in those earlier computer mags were really good and very educative. (I used to stand in regular new-book shops or roadside second-hand book shops in Chennai and Pune, reading such mags (to decide which ones to buy with my limited budget, by reading parts of many articles in them) until my feet hurt, and then leaving, after buying a few to read fully at home.) Ditto with the British Council Library, from where I used to invariably borrow 4 books (the limit) at a time. They had very good books by British computer book authors, on many topics and parts of the h/w and s/w stack.

I remember reading a very good article about Huffman coding with an explanation, figures and C code or pseudocode, by Jonathan Amsterdam, in a BYTE issue. BYTE used to have specials sometimes, notable ones were the issues on Smalltalk and Lisp (one each), in which articles about those subjects filled almost the entire magazine. The Ciarcia's Circuit Cellar column by Steve Ciarcia was great too, so much that I used to read it even though I did not have a background in electronics or hardware.

In fact, for some issues, BYTE's cover art by Robert Tinney became collector items.

DDJ (Dr. Dobb's Journal (of Computer Calisthenics and Orthodontia was the original name, IIRC) and CUJ (C User's Journal, later became C and C++ UJ), were excellent too. Many really good articles on C and C++, both on the language and algorithms for various purposes.
