VAXStation 4000/90A

Hi All. I'm taking my first stumbling steps into the world of VAXen and VMS. Before I sink my teeth in the bigger machines I have, I've decided to see if I can get my VAXStation 4000/90A to run. It seems mostly okay, I can boot the VMS cd I have. But there is one message that concerns me. During the self test I get this: ?? 000 8 SYS 0512 That last number is not hex, if I type the following I get ?? 000 8 SYS 0200 And I guess 0200 is hex. Either way, in the manuals I have found, I can read that the test for device number 8 is checking the systems ROMs and that this indicates a checksum or read error. The error code shown is not listed in the manuals. Should I worry about this? Can it be remedied? Kind Regards, Pontus.
