Hi Bojan
You have stirred up a little interest for me. I still have the motors (I will need to make some sort of a gearbox to attach them) and I have a cheap equatorial head (something like an EQ3). It has a RA drive. The standard type Sid, X2 and x8.
I also have the black box I built to drive them and a Qbasic program I wrote that controls all with a two star alignment, planet calculator, alignment star data base, M, ngc and IC data bases etc. I used to sit with it connected to a computer and watch it go through its antics while the motors drove a couple of threaded rods with pointers on them as I did not have an equatorial head at the time. At a I arcsecond per pulse gearing I got a slew rate of about 1 degree/second.
About this time I got an LX200 classic and did not do any further development.
