HI all,

I have no photo equipment, but here's a fairly dismal image of a dead 1820-1169 ARC chip.

...a magic one in the day :-)

I just worked out what the large square in the right side is. Its the registers for A, B, the stack, M, plus probably for the adder subtractor.

The lower left side is probably for partially decoding the LED display information that gets sent to the anode driver.

cheers
