Dear Apple ][ Guys,
I have developed from scratch a new graphics GUI for prodos without need of mouse, and 5 apps developed completly buy me. It's a working and tested prototype by myself for days. If interested you can try to win the auction in EBAY at this link, it ends tomorrow EBAY EASY OS AUCTION. It's a 5.25" Floppy and should works, by my test completed with Applewin and a real Apple //c on a Apple ][+, //e,//e enheanced and obviusly //c.
The ebay auction you linked is not inspiring me to make a purchase.
Perhaps a demonstration of your software's capabilities would be a better approach.
Here you can play Easy OS directly emulated inside your browser, first pass is RETRUN key.
