If so, do you know 65816 assembly? Apple published a technical library for the Apple IIgs. You can buy these books used thru Amazon.com or you can find PDF copies of them on some Apple II web sites. Two great sources are these sites: https://apple2.gs/library.php http://brutaldeluxe.fr/documentation/index.html So the answer to your question of where to start: you need to start reading. ;-) -- ]DF$ The New Apple II User's Guide: https://macgui.com/newa2guide/
