ThereSome markings on the board indicate: CPU 5004-0209. I don\'t know if this indicates it is related to the HP 5004A Signature Analyzer or not because there is not HP markings.
This looks like a fun project to get working.
Please see my other listings.are 4 empty sockets for ROM, 2 push button switches for Load and Reset. The date range on the IC\'s are from 1977 - 1979. The processor has a handwritten sticker indicating a Test date of 3/20/84. There is a 100 Pin Card Edge connector which doesn\'t appear to be the standard TI TM990 connection. The board itself is 7.5\"x7.5\" and appeared to go in a card cage. The board is in good shape cosmetically but since I can\'t test, I can not guarantee proper operation of the board or its components. The White CPU is a bit scratched but appears in good shape.
