[comp.sys.atari.st] Supra HD clock battery

cjr@cs.bham.ac.uk (Chris Ridd <RiddCJ>) (09/07/90)

  The real-time clock on my Supra drive has failed after about 18
months.  Has anyone any advice on what battery to get and how to
replace it?  The current (no current :-P) battery feels like it's
soldered in, so I'd appreciate some suggestions before I use brute
strength and break the thing.

  Many thanks!

The same thing happened to me after about 3 months. The battery is soldered
in, but it is easy to replace. I bought a battery holder of the appropriate
size and de-soldered the old battery and replaced it with this new holder.
Be sure you get the polarity correct. Luckily the holder will fit
in the space provided overtop the IC. I don't remember the details
on the holder or the battery #, take the battery to some electronics place
and ask there. I got my stuff here at Fry's - our local electronics
supermarket.

The battery in my Supra disk also went very quickly. I contacted the
UK importers, Frontier Software in Harrogate, (from whom I bought
it) and they supplied a new one free of charge. A friend with a
soldering iron fitted the new one. The new battery also failed very
quickly and I phoned Frontier again. They recognised that this was a
common problem and this time they sent another battery plus
replacement (clock?) chip, also free of charge. I've had no further
trouble and was very happy with the response from Frontier.

IT IS NOT THE BATTERY!!!! There was a huge batch of SUPRA clock chips which
are BAD, and killed the battery quite quickly. You need to send your hd
back to SUPRA, where they will replace the chip with one that works, for
FREE. I had this done and my clock chip works great now.
