Re: Nascom repair - Looking for clues please
Thanks for the interest folks it's great to get help and advice.
I've been over the board testing the 74 series chips with a tester and they all turned out OK. My tester can't do 74LS163s though so I rotated those around, still no success. I did the same with the 81 series buffers. So I've come to a halt for a while. Everything is fine but it's still not working.
Cheers,
Andy.
