Oh, interesting.

At the time it might actually have been a bit hard for the chip
manufactures to get a PAL TV and a good PAL signal generator, i.e. they
might have had do order it somehow from Europe, and a signal generator
generating a perfect PAL image might have been rather expensive.

But at the time, in the late 70's, there were probably no real market
for home computers in Europe. TI99/4A (and also the Atari 8 bit series)
were designed/sold before VIC-20.

Well, both lucky and unlucky at the same time as they had great success
for a rather long period but then just owned a bankrupt company with an
environmental disaster :)
