    It’s interesting that the gate arrays are supplied by Seiko, and the only known MCGA systems apart from IBM are from Epson. The bit of Seiko that made the gate arrays appears to be… Seiko Epson. So is it a coincidence? Sub-licensing? Skullduggery?

        The article mentions that it is brought out to the connector, multiplexed with the monitor ID pins.
