Len, steppers makes this problem very easy and it has indeed been discussed before. Searching on the term "two motors" I was able to retrieve a number of my own posts about this.
http://article.gmane.org/gmane.linux.distributions.emc.user/8147/match=two+motors is an older post describing a possible solution in words. http://article.gmane.org/gmane.linux.distributions.emc.user/10276/match=two+motors is a later posting with some boolean algebra (not HAL though - I decided to use standard 74LSxx gate logic). There are more mail about this. Use http://news.gmane.org/gmane.linux.distributions.emc.user to search the archives - it's nicer than the sourceforge archives ...
