Recently on a machine a I saw a 65SC02...
I checked the differences...
I'm not absolutely sure...
apparently there are several CMOS version of the 6502 some compatible / 
some incompatible
with more or les extra instructions

apparently the one with more instruction comes from WDC
but seems unavailable as a replacement to the standard 6502
is there a WDC version compatible (I think I saw one on jameco web site 
4 or 5 years ago)
there is also a version with a different pinout

is there a clear description somewhere of the differences / the 
available datasheet / and the available chips

I saw some nice web site explaining the differences but none with links 
to the datasheet nor information on the availability

       Message was sent through the cbm-hackers mailing list
