Must have been those processor pixies, like the ones the shoe repairer had in the fairy tale.
:lol:

So a little more explanation i guess. I still think FPUs are pretty useless but i wanted to do a few other updates on the board actually so this helps.

I saw Chucky had posted this on the facebook. I'm interested in one when it happens!

You guys realize you can just add an FPU to the A1200 motherboard and it'll work with TF1230?

But only at motherboard clock speed which is more pointless-er

a FPU? Useless!
Coincidentally there has been a MC68882RC50A PGA sitting on my desk, been wondering what to do with it since I noticed it in a drawer last week.

You just need one extra wire to run it at 28 MHz which is already available on the motherboard.

@terriblefire may I ask You to take a look on compatibility issue of the CPUs with 1F91C mask - have problems with them on TF1230, display remains black, card doesn't boot when CPU with this mask is installed. Other cards working great with them, have tried TF330, TF536, TF534 so far....
TF1230 doesn't make trouble with CPUs with older masks like 0G40W works great otherwise...
PS
also of You have a spare 1232 PCB left - will gladly take one for test purposes

Not sure i have a CPU with that mask. I'll have a rummage.
