Anway unlike most PC's where you can just slot in a new battery, I need to
order a new chip, so its down until that comes from China. I did try hacking
into it with my Dremel "look alike" to replace the battery but its
encapsulated in some epoxy type substance that seems "dremel proof" and
makes glass feel like rubber....
I've hacked a couple of those over the years.
The trick is to leave the
body alone and hack the small bead of sealing epoxy at one end of
the battery, break the wires to disconnect the dead battery, then tack
on a couple of wires that go to a new 3V coin cell holder. I bought a U60 almost 10 years ago for a couple
hundred bucks, so it's
not surprising that a machine made in the past 2 years runs rings around
it.
Actually I have one of those. I bought it so I could put an SCA disk in
my Vaxstation. Might be worth a try.
(any one any tips for DDing the data from the
second hard drive in the
U60 to a new drive, being SCA drives its not as easy as normal SCSI...)
As far as
the controller knows, it's the same, so you must be having
issues with cabling to an SCA drive. There are 80pin<->68pin adapter
boards out there that shouldn't be expensive.
Something like this...

Also, external Sun boxes were made that took SCA
drives, but those
might be less easy to track down.
I don't really want an external drive. I
think I have some "normal"
enclosures, but for a copy I might be able to bodge something up just to
DD the disk...
