Label "43" on the back.
According to the owner: The board was populated but missing the shift registers and DRAMs.owner discarded the original CPU in favor of a later-version "ROR-fixed" 6502 for enhanced performance.This was definitely a work-horse board. A better description might be 'Reclaimed from Steve Jobs' office by an employee.'
Note: See comment at component list.
Unreadable stamp on the back. Probably QC.
