But most available cards are somehow user-friendly with little flexibility. One of fewer exemptions is the card from Motion Research Institute. It does not have host processor. PC can access any axis at any time. But you maybe need to do more work on your PC host. Independence will not be a problem. But I am not sure about multi-interruption because controller chip probably doesn't have input buffer. This is a new product I don't know much about. BTW, Oregon board is one of the best boards with a very good command set. I don't know why it is not suitable for your application?

I just received the "Byte deck" of advertizements from my Byte mag subscritpion. One of the pieces of advertizing was from Micromint Inc, 4 Park St, Vernon CT 06066. Phone (203)871-6170, Fax (203)872-2204. They manufacture low-cost experimenter single board computers and industrial controllers. One of their products is a Stepper Motor controller board, for $199. It is not a PC card, it plugs into a 44-contact edge connector. But this may suit your needs. -- John Dudeck "You want to read the code closely..." jdudeck@Polyslo.CalPoly.Edu -- C.
