Mystery stepper Driver

I picked up a bunch of small stepper motors with drivers on Ebay but haven't had any
luck finding a hook-up diagram for the stepper driver. On the back of the board is
reads ROA1172493/1 and RSA 1999.

The large IC on the board is a PCF8591; 8-bit A/D and D/A converter.

The stepper is made by Minebea part number BKE90303/1

Any help is figuring out how to hook up these drives would be most appreciated.

I posted a buch of pics in ABSE

Thanks in advance!

ROA1172493/1 is probably made by Ericsson Telecommunications. You
might have some luck searching their web sites. I have boards started
with ROFxxx xxxx/x

What does ABSE stands for?

alt.binaries.schematics.electronic . To access it, you nead an ISP with
a real news server, and use a real news reader program. Google doesn't
carry binaries.

Good Luck!

A "real" news reader program is not required, OE will work fine. ;-)
