6502 analyzer: what CPU is this?

With the Chinese changing the pint on the IC’s, one can nver be sure with a 6502 which it is. I have for example perfectly good working 6502’s, which were labeled as 6502 but were in fact R65C02. SO a way to check which 6502 really is in there would be fine.

User kinzi at forum64.de designed a nice solution to check a 6502 for type: the 6502 analyzer.
The analyzer is a minimal 6502 system with clcock circuit, ROM and RAM and a latched 8 LED array to show the result.
If any of the LEDs light up after a RESET, it is a working 6502!

I have build the V2 version. There is a version 3 with improved address decoding but identical software.

Meaning of the LEDs:


Label OFF ON
CMOS NMOS6502 or 65816 CMOS
65816 NMOS 6502 65816
