I suppose it depends on "how convex" and how far you're willing to place the
IR grid from the screen. In any case, the IR touch panels from PLATO plasma displays were
not carried forward to the CRT based IST terminals. Perhaps CDC liked their technology
better even though both could have worked; at this point the reasons why are probably hard
to discover.

Theinfrared array you're thinking of was
invented at PLATO, for flat panel (plasma) displays. They don't work for CRTs because
of the convex screen.
My HP150 will have to disagree with you there.
