I found this useful, has features I needed. And needed some enhancements. So... I now have a "next" version. I called it GAG 4.11 since what is here is GAG 4.10. For GAG 4.11 goto http://www.electronics-software.com/ and select the Open Source tab. In the spirit of give and take of course this is under GNU GENERAL PUBLIC LICENSE. The site has a .zip file with full source and already built floppy image, disk.dsk.
