Hi Chris
I have been doing some experimenting with that AVIO systems board and have worked out a way that might be usefull to drive a telescope using two of the boards suitably modified to allow both to be operated from LPT1 (not LPT2 or 3 etc). By using Qbasic's LPRINT command I can get around the problem of addressing ports directly under 2000/XP etc.
I have written a simple short program in Qbasic that will allow you to test 5 wire motors for speed and mode of operation using a slightly modified board so that the LPRINT command will work. The modifications necessary are on page 6 of the instructions.pdf. The value for delay will depend on the speed of your computer so some experimentation will be necessary to establish the minimum value. The instruction manual (my version) is too big to attach so I have just included my additions.
