Even just a photo of a self-test with all of them visible would be instructive for me.

I've browsed the Free42 sources, but didn't find anything I could recognize offhand yet, and it doesn't seem to have emulated the self-tests. Why on Earth not?

Thanks to anyone who can help!

Press [EXIT] + [LOG] simultaneously, this launches the self-test. Then press [<-], then [ENTER] repeatedly to cycle through various component and LCD segment tests; eventually they will all be cycled on/off, including the BAT indicator. When done, press [EXIT] + [Square-Root] to exit the diagnostics and do a machine RESET (but this does not erase memory).
