This is a WSI (Wafer Scale Integration) chip manufactured by Trilogy Systems (probably between 1982-1984. Specific date of manufacture unknown). Image was taken by laying the chip wafer on a scanner. This is my clearest image of the chip, to date. This prototype WSI chip never succeeded in functioning.
