Seriously though, this is why adding these little safety catches - a 2p resistor (which might potentially save an old bit of silicon costing 100 times as much) is worthwhile. There is an ever decreasing supply of these expensive old devices out in the wild.

Maybe the pulldown switches on the page select and mode select inputs should also have low value series resistors in case 8154 outputs are ever accidentally connected to them when the switches are in the short-to-ground position.
