Falcon FPU upgrade

Part of a larger, longer term project
I wanted to add a 68882 FPU to my Falcon. Altho there is not a whole lot of software that takes advantage of it, the feature is there, I want to use it.
I ordered this about a month ago, and it finally arrived.
I’m assuming the 40 in the part number is the rated speed, 40MHz.
I ordered this from a seller based in Hong Kong, but ships out of Singapore. Go figure. That explains the painfully long delivery process.
I was concerned about buying this, because I’ve seen plenty of discussions about counterfeit chips. Unfortunately, I could not find any sellers in the US, and took a chance.
Open up the Falcon, yet again, and remove the power supply to reveal the FPU socket. Easy to install, just verify and re-verify the orientation.
Booting and testing.
Not sure why it says ’81 or ’82, but I know that previously, it simply stated “not installed”, so it detects it.
Now to find some software to drive it around the block a few times. But I’m still not done with the Falcon.
