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

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!

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