 Hi
     And now something for all you Decsperts to get your teeth into.
My VAX4000-300 is failing the self test.

After selecting the language it counts down to 10 and then fails test 
C5.

Does anybody know what test C5 tests.
If its an unterminated DSSI bus thats OK anything else could be a 
problem. 
According to the KA670 Tech Manual (EK-KA670-TM, it's on bitsavers.) the
C5 diagnostic is for the system support chip. I don't know if an
unterminated DSSI will cause this, but it's plausible.

Hopefully this additional information will elicit a more helpful reply.
