motor needs specific controller

Recently visited Jeroen's web site (had seen this before when researching my Super Polaris mount).

Heard back from Jeroen today.

To run the MT-1 motor unfortunately requires a controller of some form. The MT-1 is a so-called unipolar stepping motor that consists of a number of phases that need electric pulses of exactly the right length in exactly the right sequence. This requires non-trivial electronics. If you have knowledge of electronics you might be able to build such a controller. The simplest (but most expensive) option would be to use the Vixen SD-1 controller.

Looks like I need to go shopping again...
