Another 5 phase Vexta motor, but 6 wire.

I have had this one for about a year now, but have not been able to
dig up much information about how to drive it. This one has a label
that reads:

5 Phase Stepping Motor
A2487-9215
0.75A 4(ohm) 0.72deg./step
FH7-1413
C3 VY6 35174
Vexta

The resistance from one wire to the 5 others is 3.9 ohm (4?) and
between all other combos 7.7 ohm (8?)

What I would like is:

1 - Where to get a driver circuit (preferably something
cheap/homebrew) that I use to interface it to computer.

2 - The internal wiring, is it a star? or?

3 - Any info/pointers to info on this type of stepper.

Thanks
Art
