Hi Tore, I am only catching up on my email now after a weeks absence. You're welcome. I Hope you didn't have any problems transporting the machine home. If you have any friends / family / colleagues etc coming to Ireland that would be willing to transport the X.25 stuff - send them my way. I have never come across any documentation for the 3100 that goes into enough detail to explain these codes. However, the card can also be used in a Vaxstation 2000 and the firmware in a VS2000 appears to be very similar to that in a VS3100, so I had a look in my Vaxstation 2000 and Microvax 2000 Maintenance guide which does have some details. It suggestes that 0016 is the status from the test and says that this can be ignored! It goes on to say that 005 means "ID data bus" and 2 means an error (as opposed to "no error" or "informational"). Unfortunately, I don't know what "ID data bus" could mean. When I tried it last, it produced an error during the power up self tests (probably the same error you are getting) but it was possible to ignore the error and boot VMS and use Decwindows without any apparant problems. Its possible that the version of VMS/Decwindows you are using is more sensitive that the one I had. I will see if I can find out what version it worked ok with. I suspect it was V6.something. Regards, Peter.
