Actually, any such troubleshooting would involve checking for power starting from the power cord. Also, a common failure mode on the H89 was the Molex connectors. You may want to disconnect and clean each of them just for preventative maintenance. Good luck.</FONT></SPAN></DIV> <DIV dir=ltr align=left><SPAN class=718583115-20032007><FONT color=#0000ff size=2></FONT></SPAN> </DIV> <DIV dir=ltr align=left><SPAN class=718583115-20032007> <DIV align=left><FONT face=Arial size=2>Peter</FONT></DIV> <DIV align=left><FONT face=Arial size=2>----------------------------------</FONT></DIV> <DIV align=left><FONT face=Arial size=2>peter59@sbcglobal.net</FONT></DIV></SPAN></DIV><BR> <DIV class=OutlookMessageHeader lang=en-us dir=ltr align=left> <HR tabIndex=-1> A brief introduction - I'm probably a little younger than most of the group, but I started my career as a programmer (at 4 years old in BASIC) on the H89 that my father assembled. I grew up reading REMark and Sextant and helped to build and upgrade an H-150 along the way. <BR><BR>Well, I recently took possession of the H89, did a quick interior dusting and exterior cleaning, and attempted to power it on. But, powering it on does nothing. No fan, no clicks, no smoke, nothing at all. The fuse is fine. I did a quick visual inspection of the power supply (without removing anything) but didn't see anything amiss, and there's no scent of smoke. I was the last one to use the machine, but I don't remember having any problems with it. (Although, that was 15-20 years ago, memory isn't perfect) <BR><BR>Mike Shields<BR></DIV></BODY></HTML>
