Geo3,
I tried to acquire the Sider @ vintage-computer, but Matt had sold/traded it.
Initially, I thought the power supply was the entire problem since it had a couple of cooked components. I installed a new supply and even tried a bench supply without luck. Next, I planned on moving to the logic board in hopes that it wasn't the drive mechanism. One potential problem is that I assumed the power leads to be: red=5v, orange=12v, black=ground. Do you know if that's correct?
In my research on this problem, I did come across the Compact Flash drives. You're right, it may be the way to go once I get the files recovered.
FYI, I contacted an HD recovery service and it would run about $1600 for them to recover the files. Whew... That won't happen any time soon.
I'll keep an eye on the ebay Sider. When I checked, it was up to about $50.
Thanks for your help on this...
