and you were still right. software-intermediated volume is far from uncommon these days in consumer electronics

typically you're not gonna find any datasheets because they tend to be custom-wound for a particular customer application
>measure the reistances between each terminal
they often use different gauges of wire. that's not going to work very well
the best way is probably to pump a 1V sine wave into one winding and measure the voltage at the other(s). also, for these sorts of transformers, which terminals are start resp. finish is also important
but, you won't be able to make very good use of these without a short course in ac-dc converters. if you try to hook them directly to mains voltage without appropriate driver circuitry, they'll burn out
