To get RGB of any kind out of a Dragon requires a particular rare model, or some internal or external converter kit. And even then that ...

Oooh, that trap stuff is magic. Thanks for the new feature!

This disassembler / monitor cartridge appeared on eBay a couple of weeks ago. Did anyone win it, it does anyone have a copy already?

Be good to get it archived Windrush's tools were generally pretty good ...
