Help on my MicroVAX 2000

It would appear that I am in dire need of some guidance in how to bring up my MicroVAX 2000. To bring things up to a current baseline, it is equipped with 14Mb of RAM, an RD54 HD, external connection option, and has a TK50Z-FA connected to it. Except for a flat battery, the uVAX seems to pass all the tests, and the tape drive seems functional. Unfortunately, I have no documentation on this hardware except pieces that I have picked up from this list, the FAQ, and other odd pieces picked up on various websites. I have on hand several tapes for VMS - v5.4 and 5.5 - most but not all say that they are binary. Some are characterized as 'mandatory update'. At any rate, after inserting the tape (#1) in the drive, closing the door, and pressing the illuminated red pushbutton, I enter 'b/1 mua0' at the terminal. After some passage of time (accompanied by whirring sounds and flashing lights), I see on the screen: -MUA0 Then later: %VMB-F-ERR, PC = 00000765 %VMB-I-STS, R0 = 000008C2 84 FAIL If I attempt to boot with a known non bootable tape, the screen is the same except that instead of '84 FAIL' it displays: ?06 HLT INST PC = 00000E64 Regrettably, I have neither the experience nor the documentation to get me any further at this point. I really need some pointers and/or help! Thanks. - don
