I recall reading about this in a magazine back around 84-85. You could pop out the 6847, pull up a pin, then re-insert and it would be inverse. I did that on my CoCo 1. I also added some loweracse board from a company in Texas somewhere. Good times.

Okay, now I know — it’s being faked ;-) in software. Works for me!

Thanks Tim, Thanks Curtis.
