Anything special to set HW clock?

Muzer · 01 October 2009, 22:31

I've recently bought a RAM board that also contains a battery backed clock for my A1200. (This one: http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWNX:IT ). It is unbranded and if it came with any software, I didn't get it.

When you set the clock, should it stay after a reboot automatically or do you need to do anything special to write it out to the hardware? If the former, presumably the battery is dead. What would be the best way to replace it? (It seems to be soldered on).

Use the SETCLOCK comand from CLI:

SETCLOCK LOAD|SAVE|RESET

but try what prowler said first as it might just work

Sounds like the battery is dead if you've set the clock and clicked save it should stay.

They are good little ram expansions...i had one.

The bracket holding your battery is spotwelded to the battery...best bet would be to de-solder it and buy a coincell holder and solder that in it's place...or whip one off an old motherboard.

You can get those batteries from CPC. Have a look at this thread http://eab.abime.net/showthread.php?t=35291
