I recently recapped my LC III motherboard and it works wonderfully. I had an extra m68881, but it's only rated at 16 MHz and the LC III is running at 33 MHz, so I decided to buy a faster rated m68882 from eBay for $6.
I've gotten lots of fake m68040 and m68060 chips from eBay, so I was a little suspicious, but I installed it, and it's a real m68882!
Now the strange part: According to the markings on the package, it was made by Motorola, not Freescale, and it was made in 2012! I wonder why Motorola is still making these. Also, even while running FPU intensive tests, it runs cool, so I'm guessing this is a newer mask made on a smaller process than old m68882 chips made in the 1980s.
