Another great magazine that helped me get up to speed on computers was Kilobaud Magazin. I guess it's name is kinda dated in the days of Gigabaud transmissions, as a kilobaud was 1024 bits per second, or 128 bytes per second.
Wow I remember Kilobaud April 1979, that introduction to Quicksort with examples in BASIC, copying it down to carry around with me in a little notebook. Shell-Metzer was also popular at the time. I had a TRS-80m1(Z80) and Kilobaud was like a bible.
Publisher Wayne Greene (good guy) had actually started Byte magazine (sordid details) ... but Kilobaud (as Wikipedia notes) was definitely for more technical readers ... down-to-metal hardware and software wisdom. (I only recently parted company with ish's #1 and #2.)
