"three phase" sig gen?

[Merlin Zener]

G'day all,

I was wondering if any of you gurus could help me out with a
simple cct for a signal generator. The outputs I want to be
like this:

     __
1.__|  |______|
        __
2._____|  |____
           __
3.________|  |_

It has to run off a 9V battery, other than that there's no
particular requrements I can think of. It's for a new type of
universal cable tester I'm thinking of.

Once I get it up and running I'll post a link to the complete
cct back to the list.

TIA
