[sdiy] OB-X data needed

[john mahoney]

Anybody have an OB-X, a voltmeter, and a little extra time? If so, please
contact me. Thanks!

I'll explain: I have 2 OB-X voice cards but no OB-X, and I'd need to know
the voltage range that can be present at each of the motherboard connection
points; this is not documented in the copy of the service manual that I
have. The goal is to use the voice cards outside of an actual OB-X. I'd
rather not kill something through ignorance.
