Can anyone shed any light on this weird fault.
On turning on the BBC, it makes the first tone, but not the second. It
displays a mode 7 cursor where you'd expect it to be (after BBC Computer,
Acorn DFS, BASIC).
Typing has no effect. After pressing BREAK (or CTRL-BREAK) however, if you
type, the cursor will move along, as it usually does.
It seems to respond to commands, e.g. CLS moves the cursor to the top left.
The fault is not a teletext fault, as it happens in all modes.
It's like the computer is working fine, but none of the characters are
there. Also, typing something like DRAW 1000,1000 doesn't change the screen
at all.
The only thing I've tried is swapping the Video ULA, which has no effect at
all.
Thanks in advance for all your help guys!
