I've got 11/13 production MS 85 w/ tech package on 2019.20.2.1 and have never been able to access Sketchpad. When I triple-tap the "T" at the top of MCU screen I end up with the Atari Arcade selection screen. Anyone else experiencing this or has an explanation? I have no issues with playing Centipede while road tripping, but thought my wife would get a bigger kick out of Sketchpad.
