I watched Bits alot.
The three ladies were:
Aleks Krotofski (the one with glasses)
Emily Booth (one with pig-tails alot of the time)
Emily Newton-Dunn (the other one)
I don't have any episodes as far as I remember. Although they were true gamers, they did spend quite a bit of time messing about infront of the camera. I won't mention that Emily Booth used to have a website, that I once bid on her underwear or that she has done a few adult films.
As for Amiga, I don't recall anything Amiga-related on the show as they primarily focused on the games consoles.
