Theory about Fidelity Research MC & PMC Carts


I have a theory that the Fidelity Research MC 201 and 202 were the US market version of the PMC-1 and PMC-3. They were all produced from 1980 to 1984 and the specs on each look very similar.

Also, I have searched the entire internet and found no evidence of either the PMC’s being available in USA or the 201/202 being available in Japan.

Does anyone have any info to support or reject this theory.

Thanks in advance.

I didn’t mention the FR 2 in my post. I am only curious about the ones I referred to. 
I see, but FR-2 and FR-MC 202 / 201 have at least similatiry in numbers, like the FR-7 series and FR-702 (which is an Export version).

PMC-3 is a different cartridge, do you have PMC-3 to compare it to the MC-201/202?

Look at the old J.Carr’s posts about PMC-3. This is the closest model to FR-7 series.

The question is about identity while identity theory already

exist. Say for someone who does not know that Vienna is

the same city as Wien (German) , Wenen (Dutch), Bec (Serbo-

Croatian), etc. We are used to think that names have unique

reference. But there are different names with the same reference.

This made ''logical conclusion'' about the truth possible :

''whatever is true about Vienna is also true about Wien, Wenen

and Bec (grin). This is called ''substitutio salva veritate'' . One

can substitute any of those names for each other and retain

the truth.
