Hi there!
My calc crashes often with the reason "Data error 20. Consult user manual".
But there is nothing said about the error in the manual.

I don?t know, wether the error comes regulary or not.
The cursor doesn?t move, but SHIFT+AC works, so i am able to turn the calc off.
Sometimes it works as normally, sometimes there is the data-error screen,

Is anyone able to help me?

If I remember right when I was modyfing first ROM-DISK (A:, that is system disk) my calc returned me error 40 or error 20, depending which part of the disk I modified.
Probably all you need to do is to reset the calc - run test mode ZX945 (turn off the calc, pres F6' />,[a b/c], buttons simultaneously) and try those options that reset the memory.
Anyway the calc itself should ask you about reseting storage memories when this error was signaled.
Please say about the result.
