The price is good, but only if the processor is authentic. I would be more comfortable with it if it would not claim to be original RCA. I think they only produced the CDP1802AC, the ACE came later, when RCA was no more from Harris or Intersil.

The one I have here if from Harris an is a CDP1802BCE. They had traded in the option to run it at 6.4 MHz (at 10V) for 5 MHz at the more practical 5V. I had it running at 6.5 MHz on the breadboard yesterday and it did not even get noticably warm.

Anyway, if the processor is ok, that's already a good deal. The rest? Yes, you could use the EPROM and the RAM, but better ones are not really more expensive. The question is, how 'retro' you want it to be. These parts are inbetween. And you would need some 74HCXX logic. They also are not retro. 74LSXX will not cut it. They are pin compatible and may even work, but it's never a good idea to mix different logic families.

For me the that question is easy. I already have retro sitting on the other desk. Even still working, if you overlook some parts showing their age. I will not hesitate to use whatever is reasonable and available for the Zwölf, including bigger and faster memory or using PIC microcontrollers. The circuit board is going to cost more than the parts that will go on it anyway.
I have lived with several Zen masters - all of them were cats.

His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.
