There is scads of this information available on several different types of
controller hook-ups, e.g. bipolar, unipolar, L/R, chopper, etc. A good place
to start is at the following BBS - "www.eio.com\public\stepper" Of
particular interest is the Ericsson and SGS-Thomson Websites. Sorry but I
can't remember then and I don't have them marked. Check out posts by Kevin
Carrol as his design used the Ericsson chips. I used the SGS-Thomson set.
Kevin has since died but I and others have his board design.

Hope this helps...
