Newbrain AD - Error 2 at 257

Hi!

I've got an old Newbrain AD, but I only get "Error 2 at 257" no matter what I type in. Tried "print free" and it returns "Error 2 at 257". Tried just garbled text, same return.

Where do I start looking for faults?

Cheers!
Tomas

Re: Newbrain AD - Error 2 at 257

Hi

Error 2 is 002 "Arithmetic error,eg tried to divide by zero, arc sin of value >1"
but i think most probably its a hardware error.
Check for capacitor leaks and the nearby ICs.
Check the memory chips.
