     It's not the old keyboard ribbon playing up is it?
     
     I seem to remember a single beep and a flashing cursor when turning on 
     the beeb when the keyboard is unplugged.

Hi
     
Time for the soldering iron......
     
Problem: Issue 4 BBC B only boots to a flashing underline in the top left 
with a quick beep.
     
The last thing I did before the machine refused to boot was to push down the 
socketed IC's in the "Econet area" down to make sure they were properly 
seated.
If I remove the NFS ROM the machine boots. 
If I make link S2 the machine boots.
If I remove IC 97 the machine boots.
Swapping IC97 for a known good IC doesn't help.
     
Any ideas which track might be broken ? I've had the magnifying glass out 
but to no avail.
     
Mark
