Hi Steve,
An 030/50 can most definitely cause a hangup through overheating.
I had a Microbotics card with this CPU and when I fitted into my standard A1200 desktop, it stalled all the time when running CPU intensive stuff like Imagine (3D rendering - you can't get more intensive than that).
I tried a heatsink/fan and tht workrd OK (if you can stand the racket!) Eventually, I just jacked up the keyboard using rubber door stops as legs and removed the trapdoor to let air into the slot area. That worked a treet!
Cheers,
JaXanim
