@Daedalus on the TF360 and I guess would be the same as TF1260 I think it's the CLPD's getting too hot which was causing me lock ups (I am using a Rev 6 060).
Note this only happened at 75mhz at long periods and that very very rare occasion that the weather made it ~30 Deg c ambient in my room.
My use has 90% on demos running at 75mhz, and i have have clocked up many many hours and it has been fine in 'normal' UK weather.
The TF360s had small raspberry pi style heatsinks on the CLPDs, i did remove those and add taller ones due to the extra height available in CD32 expansion bay.
Enjoy the TF1260 you lucky ...
