Unlike today, in the 1980s most computer magazines like BYTE, Compute!, and PC Magazine had lots of articles about programming and programming languages. BASIC, Pascal, Prolog, Lisp, Forth, assembly language; you name it. In 1987 C was a very popular language and a good C programmer made good money so I decided that I should learn it.
I found an magazine ad for MIX C headlined "C for yourself". They had a very special deal called MIX C Works and this included the compiler, a split screen code editor, and a source level debugger for only $89.90. The ad claimed that the included book would make learning C easy. I paid for this software myself, and it was so exciting to open the package when it arrived in the mail. Nice new crisp books and disks. It all felt very professionally done. It was a great investment.
It was very exciting to dig into the C tutorial and use the editor and the source level debugger. This was really well written software and book was as good as the ad promised. C is a nice, small language and well written C is actually quite pretty to look at with those curly braces.
We had some simple applications in engineering that were perfect for learning a new language. Open a file, translate the information in some way and write it back out to a new file.

COMPUTE! Magazine
Computer magazines used to be so much fun. First of all most of them had a very strong focus on programming and they would have articles about how to make electronic hardware to plug into your computer. Very much fun indeed.
Since I was the owner of a Commodore VIC-20 I would buy issues of COMPUTE's Gazette which catered specifically to Commodore 8-bit computers.
I remember one issue which included a machine code monitor listing. The program was in BASIC and it would POKE a machine code monitor (in machine code of course) into memory and then it would start up. I experimented with 6502 assembler using this monitor. I would write the assembly code down and then I would translate it myself to hexadecimal numbers and type them carefully in.
This was one of the great things about the computers of those days. A fifteen year old kid could figure this stuff out by reading magazine articles. There's probably no reason why it can't be made relevant to young people today. Why not make a cool and easy game programming tool for the Nintendo DS for example?

The VIC-20
In 1980 Commodore introduced a new 6502 based $299 home computer called the VIC-20. http://oldcomputers.net/vic20.html
It was essentially a version of the Commodore PET that plugged into a TV set. For the price there was nothing like it. It had Commodore BASIC built-in, color and sound, a joystick port, and a cartridge expansion slot. It didn't have graphical sprites, but it was still capable of video games and it cost about half the price of an Atari 400.
I wrote a lot of software for this machine at NEECO where I hung out. It didn't have full screen graphics, but you could program the graphics characters on the fly. It did have a very low screen resolution (22x23 text mode, 176x184 graphics mode) and it only came with 3.5K of available RAM out of the box, but we were very used to limited memory back then.
Compute! magazine had some really great software listings for this machine, like a graphics character editor for example and a machine code monitor. Just type it in and go. :-)
