Hi,
Reverse the keyboard connector and see if the problem transfers to the Q
and ctrl keys.

The keyboard connector shorting is the most common fault on a BBC. This
will need to be replaced. Unfortunately they do not sell single edged
keyboard connectors any more so you have to use one row of pins form a
dual one if you build your own.

Subject: [BBC-Micro] Dead Beeb?


Morning,

Just got my hands on an old model B, turned it on last night and all it
does it emit a constant tone and the screen flashes black and white.
I've had a look inside, but haven't really got a clue what I'm looking
for to be honest. There's only 2 roms in the slots on the right hand
side - labelled something like 8343 and 8403 (sorry - I wrote the
numbers down, but forgot to bring them in!). Is there one missing?

Can we rebuild him, or is it dead?

Cheers,
Tim.
