Blizzard 1260 unstable.
« on: July 07, 2004, 01:33:00 PM »
Hi all...
Currently I've got an A1200 equipped with an Blizzard1260/50MHz and SCSI. It was very very stable for a few years but now... it crashes all the time.

Normally when you turn on the computer you would see the rasterline-flashes incicating the card is running. Sometimes it stays black, sometimes the flashes stop halfway and leave a black screen and sometimes it boots perfectly untill I put a coffee-mug on the desk orso...

It all indicates a loose connection somewere.
The card was send to repairs, they claimed to have done something with it but problem remains.

The powersupply is a modded PC supply giving plenty of power.

Disbaling the SCSI (remove) doesn't help
Switching RAM doesn't have any effect

Is there anyone who had the same problem and can tell me what to do ? I can modify the board if I want to coz I'm an electrical engineer but don't know were to look... :(

It's all inside an A1200D, leaving the CPU-cover open and no other hardware connected....
 :-?  :-?

Actually I removed the battery coz that fixed my 030 card one time. So it's not located on the board anymore. It didn't change anything though so I might have to look at all the solderings...
Thanks!
