This Real Time Clock addon was published as a DIY project in a special edition of the the German magazine: [[CPC Schneider International Sonderheft]] (, issue #3-1986).
Like most other homecomputers of the era, the Amstrad CPC did not include a Real Time Clock. This project overcomes this limitation.
== Notes ==
Also in 1986, the same magazine released another RTC ([[Schneiderware Real Time Clock]]) 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).
