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?
A fucking built-in genlock? For years I thought only Amigas had those!
Put on the die, but only expose on the $$$$ builds using it?
The article mentions that it is brought out to the connector, multiplexed with the monitor ID pins.
