If you have an INTV System Intellivision and the worms in Worm Whomper don't display correctly you might have a Tutorvision. It should also be obvious if you open it up and look at the mainboard.
What's the serial number of your Super Pro System that's Tutorvision compatible? Does it have the Intellivision grom/font or the Tutorvision grom/font?
The Tutorvision mainboard revision is dated 1988. INTV Corp made systems from 1985 until maybe 1990. So there could be a few out there. Hard to say when exactly or if that board revision went into production. I think the one Intellivision Productions has is branded INTV System III, so those might have it as well. I'd assume it would be late serial numbers.
And to emulate Tutorvision you'd need a recent jzintv and a copy of the tutorvision exec. The tutorvision grom is optional.
How is Geo Graphics? It is a level 2 game so it should be a little more interesting than the other two.
Like Alex pointed out, if the old Mattel games say copyright INTV it could be a tutorvision exec.
