uVAX II Bugcheck help

I have a couple of newbie questions re: the uVAX II that has come to live with me.. One is (and I have looked before asking) where might I find more technical data than the User's Manual seems to provide? Particularly sysgen info.... I need to a) find some device drivers and b) make them available to VMS.. specifically the TK50. There are no floppies installed. (nor in my other one.. boo!) Two is.. this old beast got quite cranky on me this morning.. it crashed loudly five or six time before stabilizing... I managed to capture the info once or twice, but I cannot verify that it was the same each time... most crashes came during boot after VMS signed on and somewhere right before/during the DATE/TIME prompt.. though it happened at other times too... FATAL CRASH Bugcheck... PGFIPLHI Pagefault IPL too high Crash CPU 00 Primary CPU 00 and a ton of other stuff... registers etc. which I will not reproduce unless asked. ;} It *seemed* to get better as it warmed up.. the machine is out in my shop and the ambient is about 68F and foggy... also it is not retaining the DATE/TIME info... is the uVAX as sensitive to it's battery state as some other machines? Has the RAM developed mange? Today I will move it in to the house where it can be given TLC... by the way, I have been asked re: the cabinet it's in.. it is in a 4' high roll-around rack, whose top hinges up to allow access to the Cipher 9trk tape drive. I don't have the cabinet model number. Thanks to All who have offered comments/suggestions so far! Cheers John
