Thanks - it would seem 6.5MHz is indeed the correct frequency, however
I am still getting no video output.

Under simulation I'm getting hsync and vsync at the correct times and
they appear to be the correct width. However, there's no video data.

Was wondering how long it takes before something appears on the
screen. There's no vsync until 600ms, then it's regular. I've
simulated up to 1s and so far nothing - but it could be that the
screen is still blank waiting for the rom to initialise?

Anyway, not sure what else could be wrong - I'll try simulating for
longer... any ideas anyone?
