- Since our mailer/posert here is really SLOW, I can't tell if I sent this to
- this group or comp.sources.hp48 so excuse the bandwidth if this gets posted
- twice. It is a schematic for a simple motor controller based on the
- intel/amd 8031 or 8051. With a little software it can be a very
- complicated controller. I will post some code when time permits. The file
- is in postscript format (sorry it is all I have without redrawing the
- circuit, let me know if it a problem)
-
-
- send e-mail to robertt@n33.stortek.com (dont rely on the headers for the
- correct information)
