Thanks for reply Skip, 25V did seem to work best. I ran the chips programmed @21V, and they worked as well as those programmed @ 25V, just slower programming got my attention as I did not have specs for chip. 32k shouldn't take long to download Maybe the software has a little logic to it, to make up for errors on programming voltage.
