Is the Famiclone controller 3.3V or 5V?

Hi folks,
I've still not put my Gigatron together, but have been repurposing the controller.
It seems to work at 3.3V but not correctly at 5V. If anything what I had read (outside of the Gigatron project) had led me to expect it to be the other way round.
Inside the controller there isn't anything terribly informative, just an epoxy blob that I presume covers a CD4021 shift register.
Does anyone know what the actual spec of these controllers is?
Best wishes,
Tom
