finally success !!!
With only the CPU and the memory boards and the RDQ3 in the system I was
able
to boot into VMS 5.5. Had to reboot with "b /1" and "set uafalternate
1" to
circumvent the
login but it worked.
Now let's start some serious learning about VMS ;-)
Tomorrow we'll see about the other boards and the batteries are propably
gone
but those things seem manageble now
thanx everyone for the help
