Part 1 of the [[Schneiderware]] DIY series from Peter Richter released by german German magazine [[CPC Schneider International]] contained some theoretical background on the DIY projects that followed in the next issues.
The introduction explained basic questions - like "what is a data bus? what is an addresss address bus? what are control signals? what are AND and OR gates?" and so on.

Some articles also contained barely described jumpers, undocumented I/O addresses, and example programs in machine code (as hex dumps since printing the complete source code would require more pages), which meant that one needed to do some reverse engineering to understand the software and hardware. For some projects, the source code was released on the magazines Databoxes that could be purchased optionally (instead of entering the type-in listings).
