Nick Gammon's Arduino VGA with tiny 85 - possible?

I might give this a try, but the tiny 85 looks like a fantastic fit: it has TWI and the three other available pins.
TWI is on PB0 and PB2, leaving PB1 (PWM), PB4 and PB3 available (PB5 is /RESET).

Nick's diagram and sketch use Arduino pins 1 (TX), 3 (PWM) and 10 (PWM) to drive the VGA output, but I only have PB1 available with PWM on the tiny.
From what I can see, the sketch doesn't make use of PWM, so I'm wondering if the tiny would work to drive VGA. This would make for a very small "controller" and the whole setup could be connected to the master controller via a 4 wire cable, including power.

Thanks for any ideas.

would need modifications to work on the tiny 85, since the tiny 85 doesn't have the usual timer 1, it's timer 1 is the 8 bit high speed, instead of the usual 16 bit

It does make use of the timer output compare (pwm).

The 84 would be a better bet, since it's timer 1 is the normal 16 bit one

Thank you very much, Doc.

That's a 'D'Oh!'. I already have an 85, but not an 84, so I might just go with the 328.

Thanks again.
