Somebody recommended them as a cheap voltage source, but there is absolutely no information on them. |

Some time ago I bought a Ronan X85 Calibrator as a nice weekend project. The only data I could find was a brochure basically saying that it exists. No manual, nothing else. >:( The unit was sold as "Used, fully working". As received: nothing worked. Display lit with all zeroes, none controls worked, output was fixed at around 4 volts.... I kind of expected that something could not work, but not all. :-// The first thing I noticed was that it had a charger, so it probably had a battery. A bad sign, since the 80s it could corrode through. But as it was a "weekend project" I decided not to return it. As you can see, corrosion was not that bad. It was probably stored vertically and the acid did not reach the boards. |

It's interesting that different boards were probably designed by different people. Just look at these traces. ::) |

I have never seen this battery type. Does anybody know if it was a custom or just abandoned type? |
