Help! The Dectalk PC is hosing my clock!

[Charles Crawford]

I wish I could remember my Jiffy_Delta and delay settings but I think 
they were the default settings.  I do remember a bit of trouble in 
getting the dec pc to shut up with the control key but nothing serious.  
As was suggested by a message from someone else, I don't understand why 
you would have the problem you are having.  The only thing about which I 
can speculate is perhaps a hardware interupt issue?
