[X4U] Repair PB 867

[Robert Ashton]

I am positive that you have  a ram  problem. On machines that only  
have one ram module, if you pull that module out  and  turn the  
machine on you will get a single tone. This tells  you that ran is  
missing or not  being recognized. Ram not being recognized is from  
two things. Bad ram or dirty contacts. So the first thing that I   
would try is cleaning the contacts. You can  clean the contacts  
using  a pencil eraser. Make sure that you ground your self first. If  
you watch the  contacts you should be able to see the oxidation being  
removed from the  contacts. Even if you have  bad ram your machine  
could still run. This could explain why it took 15 hours for drive  
10. I have  never used drive 10 so I don't know for sure if 15 hours  
is realistic.  Bob
