Matchbox sized 6502 / Z80 / 6809 Co Pro

Indeed they are, as built. But every expansion added is another element which might push something out of spec. Even then, a lot of things just work. But in both Matchbox and Pi we have seen that we have to be careful, and that individual machines differ, even before you add the various popular expansions.

is a R6502AP CPU http://www.cpu-world.com/CPUs/650x/Rock ... 502AP.html compatible
with a SY6502A http://www.cpu-world.com/CPUs/650x/Syne ... 6502A.html they are both 2 Mhz ?
They look the same to me

Just for interest to others that may have the same problem viewtopic.php?f=44&t=8852&start=1140#p183626 with the LX9CoPro, today I got another UM6502A processor chip put it in and no problems with the CoPro works perfect (Elite ran flawlessly) with a new chip in so I guess my old CPU is a bit dodge, as the CoPro did work with a 65C02 in in BBC but wanted the correct CPU in there as a lot of software that use no-standard op codes will not run on a 65C02.
