RTC Replacement

[avctech]

I managed to check all the connections this morning and found that pin 15 (RXW) isn't connecting. It looks like when I removed the existing chip I must have damaged that track

The track for that pin isn't visible so does anyone have any suggestions on how I can repair it?

Cheers

This week I'm doing tech support for a CSIRO cluster. I got much more satisfaction in seeing that Falcon working again. Nice one.

Switched Falcon on today, and it doesn’t boot

This is all I get...anyone got any ideas?
