Subject: BBC Model B keyboard seizing up

I am trying two activate two Model B, and both have the same problem. One 
starts up with Wordwise-Plus, the other with Printbox. Printbox comes up 
displaying Printbox, but no prompts and pressing any key thereafter does 
nothing. Wordwise-Plus comes up with its options menu, but again no key 
press then works. After much powering off and on, I did manage to get *B. 
to work, and a few minutes of keys working, eg a short three line program 
in Mode5, so the computer itself is working, but then keys stopped again.
After a few breaks, screen displayed 4EEEEEEEEEEEEEEEEEEEEEE but nothing
more. What is likely to be the cause? It is odd that both machines have the
same fault.
