The TutorVision is a mix of different INTV models: World Book console has a power on LED just like the INTV III, but the buttons on the keypad are bubble-style and not flat like the INTV III.
The "orange" Intellivision
has a distinctive appearance:
grey and gold cladding and trim, a blue plastic encircles the keypads,
the Tutorvision logo on the top portion of the console, and the World Book emblem on the bottom, the power-on LED on the lower right in between the off/on switch and reset.
On the inside there are some changes from the old Intellivision model I: the boardset is now just a single board, the chips are all dated 1988-90, the board is dated 1988.
