Jim - Thanks for explaining the "H". I wonder why a parity set would
be read only?

Jack - You're right, it is fun. I've never touched an i machine before
and I'm enjoying playing with them. A friend thinks he might have some
tapes, so if he can find them I'll try to do a backup of the one that
IPLs. With that in hand, I could try reinstalling V5R2 to get some
useful privileges. Though I might try mounting a drive on a Linux box
first, to see what I might see. I think I've found the thread that
Roberto mentioned - I could maybe muddle through on the expertise, but
the time might be an issue.

As for the other one, I think I'll have a look at the Recover disk
unit functionality in the DST (nothing to lose!). After that, it's
probably a matter of pulling drives, then reinitializing two or more
as a RAID 1 or Mirrored set and doing an install. At the very least,
that would let me test components of the system to figure out which
might be useful spares and which to discard.

OT, these went on the back burner today, while I liberated most of a
pdp 11/73 from an industrial controller. Too many projects, too little
time - and that's not counting the fact that I still need to make a
living.
