Slowly, we're starting our house-building project now, so I've got a bit
more than usual on my plate.

The power-grid thing is solved for all I care, the Traco TEN60 DC/DC provides
a 24V rail stable to within a millivolt for EUR100
http://phk.freebsd.dk/hacks/HP5065A/20150930_dcdc/index.html
My plan is to design a new A18 containing:
* Traco TEN60
* Suitable -24 V DC/DC converter (to replace the one on A15
* Filtering
* "ideal-diode" input circuit to choose between AC and DC supplies
(Currently using:

Just need the time to do so...
