No. None of my Jrs have a 9928A. See for yourself:

Also no:

I think the key point is that the systems do in fact make regular composite
video internally (it's just not exposed on the rear ports); otherwise,
tapping the RF modulator to get composite video wouldn't work.

Right, but the explanation is simpler; the Mk II has the same ROM as the
Tutor-1.

I don't understand why Tomy made the Jr English. I agree that was a poor
decision given its target market.
