He didnt say a jumper. He said a jumper wire.markus0321 wrote: 31 Jan 2022 22:44
I have a revision of the A1200 2B board and I do not see a jumper for 28MHz FPU on it, I also do not see such a possibility in the diagram. I soldered the FPU socket and it works fine for me, but where can I find this 28MHz jumper for FPU on the board?
I'm sorry I didn't understand exactly. I checked and soldered the FPU CLK signal to the generator on the board using kynar and it works fine with 28MHz frequency on FPU and with TF1230 :-)terriblefire wrote: 31 Jan 2022 22:54He didnt say a jumper.

You need to lift the FPU CLK pin and solder a jumper wire to the 28Mhz clock
No, as the 060 lacks the external FPU interface. However, using SoftIEEE will give you a faster performance than a 68882 would.patracy wrote: 23 Oct 2023 17:48 Is there any way to trick the onboard FPU to be used/seen by the TF1260 like the TF1230 can?
