I am using machine sockets and I check my soldering with a magnafying glass for a visual check, then I check with my meter for shorts between pins. So I must be missing something.
Murphy's Law -- and nobody is immune!
Other stuff to look for:
- schematic error (eg: pin number mis-identified)
- wiring error (wiring doesn't match schematic)
- '573 lacks proper GND and +5 connections
- defective '573? Unlikely, but a shorted input pin would upset the VIC
Happy hunting! Sounds like you're getting close.
