File:Mattel Intellivision Keyboard Component Power Supply Schematic 1149-9099 (1979).pdf
Summary
[edit | edit source]Mattel drawing 1149-9099, "Schematic Diagram - Power Supply, Keyboard Component", one sheet, marked "Confidential". Drawn by JHL and designed by SAH on 11 June 1979, checked by JHL on 7 September 1979. It shows a linear supply with 7805 and 7812 regulators and every capacitor value. It refers to fabrication drawing 1149-4249 and assembly 1149-9249. Later Mattel documents list a switching power supply assembly (1149-9219, schematic 1149-9209) for production units, so this drawing may not match the board in a given Keyboard Component.
