re: #91 Joe Bacon πΉ
Just like Xerox created the first PC with a GUI and a mouse. They never patented itβ¦
Commodore had a GUI for the 64 later in itβs life (I had the GEOS programme for my C-64), called GEOS, released in 1985.
It primarily suffered from speed: The C-64βs 500k clock speed made GEOS run a bit slowly.
