A drop in replacement for the MOS 6560/1 in the Commodore VIC-20
Probably
Haven't even decided if I want to offer it at all. If I do, it probably wont be cheap. Small batch, very niche hardware is a good way to turn money you have into less money ;-)
No. I intend for it to be a drop in replacement and nothing more. It will aim to mimic the output of the original chip as much as possible. The closer we get to exactly the same, the more successful I'll consider it.
Let's get it working at all before we even BEGIN talking about a timeline of any kind.
