uVAX II sleeping...

sleeeping.....sleeeping... sleeping in a Jar (the Jar is under the bed) [sorry... had a Zappa flashback just then. Please disregard.] Ahem. Encouraged by the success of my more recent uVAX resurrection, I this evening powered up another one I have had for some time. It doesn't do much. So I have some questions re: uVAX autism. First off.. am I making a semantic error? The exact wording on the badgeplate of the 'good' machine reads 'VAXSTATION II/RC' and the dead one reads just 'VAXSTATION II'... all this time I have been refering to them as 'MicroVaxes'. Dumb? Irrelevant? Crucial? The VMS manual that I have (Thank you Bruce L. !!) seems to correspond with the sofware as extant on GoodMachine. DeadMachine is configured (externally) just the same as GM, ie. all the switches and controls are at the same settings. I am using a Decwriter III as the console, to have hardcopy. Upon power-up, the LED display on the back shows 'A'. The fixed disk, a Micropolis RD53-A, spins up and coasts down continuously. Cycling 'HALT' on the front panel causes the usual 'break' monitor printout and the pc state. The LED displays '8' and that's it... I have let it go for 10 minutes.... I have checked the power supply voltages.. all nominal. I have power-cycled the unit a few times.. same behavior. I have re-seated the CPU and MEM cards.. no change. In the absense of the System User Guides / Operating Manual / Processor Handbooks.. I am stuck here. I remember a thread on the disk drive's spin up/down routine, but I forgot the cause. I will gladly pay for some more docs for these machines.. any spare MicroVax Orange Notebooks out there?? Thanks in advance for any Info... Cheers John
