Dave, Code looks good. I use "ex de,hl" (i think that's the right order, opposite order doesn't work) instead of push pop. Don't know if there is a...

The purpose of the G2002 is to get around some shortcomings of PC based "software only" solutions for motion control applications. By making it open source,...

Steven, A .wmf is a "windows meta file". You should be able to view it with Win98, Win2000, WinXP, ACDSee viewer, etc. When I get a chance, I will convert them...
