Okay, looking to all of you for help.

I am still having the same issue,

that is the flashing ? folder on startup.  Basically my hard drive is not recognized because it does not appear to be powering up.

This issue has plagued this computer since I undertook this restoration project.

Here is what I've done:

1) Replaced PRAM battery w/ a brand new battery -still same issue after startup

2) Replaced ALL capacitors on the motherboard ...after doing that, still the flashing ? folder at starup

3) Purchased new hard drive from "Uniserver" (thank you)  -plugged in and still had the same issue

4) Replaced ALL capacitors on the logic board, -same issue.

This computer has a ton of new parts in it and once I get it going I feel like it will run for a very long time.  Yet just can't get the hard drive to spin.  Suggestions/Ideas?

I read somewhere that someone had a somewhat similar issue, the culprit was a 6pin connector of some sort on the logic board? ..
