Well this weekend I brough back an osciliscope to try and get to the bottom
of the problem with one of my Beebs.
As you may/may not remember I was having a problem that when econet is
enabled then the computer hangs at start up. No beeeeeeeepppppp, just a
flashing cursor top left with caps and shift lock both being lit.

All the econet chips are ok. They have been swapped with a known good set,
and the old set tested in another bbc. All were ok.

After studying the circuit I have managed to find that the IRQ coming out of
68b54 on pin 7 is always high. The 68b54 itself is OK, it works in another
bbc. I am going to keep having a look at the diagram, but if anyone has any
ideas..... please drop me a line.
