Di seguito le informazioni storico-tecniche teoricamente "più salienti" del "Joe Decuir Engineering Notebook — 1977", così come sintetizzate da Rybags sul forum di AtariAge (LINK):
"- Early reference to GTIA as "TIA2".
- Some descriptions of text/grapics modes only up to 160 pixels. References to graphics memory as 4K (maybe that's why we have the 4K LMS requirement instead of 8K).
- Page 100 "Seperate refresh cycles from object fetch cycles" (40 col text doesn't do this).
- Colleen/Candy project has reference to "Elizabeth" (a 13" colour monitor).
- Some references to 6509 (enhanced 6502 with linear memory adressing)."
