Re: Can I build with HC rather than HCT series ICs ?

Thank you for the answers. I think my friend's thought was that if HC series were used throughout then there would be no issue with mixed logic levels and you would just get the advantage of the better noise immunity. He said that on his *brief* inspection he couldn't see anything that specifically ...

Can I build with HC rather than HCT series ICs ?

Hello folks, First time poster, though I've had the kit unassembled for at least 2 years ;-) A friend who in theory knows what he is talking about suggested that if I build my Gigatron using HC rather than HCT series ICs then it should be "more reliable". This sounds like the sort of thing...

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 t...
