Talk:MOS Technology 8502
Differences from the 6510: The 8502 has an extra I/O-pin and lacks the PHI2-pin. This should be listed on this page (since it talks about the evolution from the 6510).
After looking at the reference for the HP35s, I question whether the Sunplus 8502 is the same as the MOS/CSG 8502. It appears that the Sunplus model is a microcontroller that includes ROM, power management and an LCD driver. The MOS 8502/CSG 8502 never had any of that. So, unless somebody can confirm that the Sunplus version is the same as the MOS version, or even a 650x derived chip, the section should be deleted. -- Dinjiin (talk) —Preceding undated comment added 22:49, 1 July 2009 (UTC).
