See:
http://overton.tamu.edu/aset/krajci/
specifically:
http://overton.tamu.edu/aset/krajci/dobsonian/dobsonian.htm
..and specifically the bottom part of the page that goes.... "you will
see a protractor on the elevation trunnion, and a tape measure wrapped
around the circular ground board. These were used as alt-az setting
circles, with a 386 laptop converting RA/Dec to alt/az in real time. (If
anyone wants a copy of this free, home made QBASIC software, please contact
me.)"

and this picture to show it:

If you have a laptop laying about...even a 286 laptop...you can make this
work.  If you want my QBASIC software just ask.  You will have to modify
the code a bit for your particular telescope.  If you are not good with
QBASIC I'll help modify the code for you.

I hope this helps,
