One of the things I've done the last couple months, is to test my VAXstation
4000's.  The VLC and 60 will boot with a dead Dallas RTC chip (the battery
is built in).  The 90 won't, and if I remember correctly this was the
failure I saw.  I simply bought some DS12887A+ RTC's, and swapped them out
in my 90, VLC, and one 60.  I still need to swap the chip on the 60 that
runs 24x7 (DECnet area router).

Something I did notice with the spare 60 and the VLC is that they needed to
be sitting plugged in a bit before they come up, before I swapped the RTC
chip.  IIRC, I saw this on my AlphaStation 200's, and the 500 as well.

Once I had the 90 running, I put a SCSI2SD board in it, and got it working
with an LCD monitor, and I'm now using it again.
