I wonder if it's a conincidence that the PERQ POS
filesystem recovery
tool is also called 'scavenger' and that the PERQ filesystem also stores
all the pointers at least twice so it's posisble to recover from quite
bad disk corruption. Not that any PERQ had a dmountable hard disk.
The ITS ("eye" "tee" "ess", never "it's")
operating system for the PDP-10
also has a filesystem component called the scavenger, and there's unlikely
to be much influence between that and the Alto/PERQ. It's kind of an
obvious name, isn't it?
