These 6502A Micropocessors have an on-board clock and operates at 2 MHZ. These are pulls from arcade games. They are made by various manufacturers with the same features. All are tested, working.
All of these 6502A chips, in this batch, have been tested on our MC6xxx CPU tester. We do this to be sure they function properly.
See the tester below. This is not a simple NO-OP tester. Several test routines are run.
