== Notes ==
Also in 1986, the same magazine released another RTC as part of the [[Schneiderware]] series (published in the normal issues, not in the special Sonderheft issues). Both solutions used similar but not identical 4bit RTC chips (the chips have different pin-outs, and some of the 4bit registers aren't exactly the same, for example, the leap-year bits are different).
