Parellel port questions

[Brutman]

What happened?

I killed one parallel port and I was not happy about it - excessive heat to a chip probably due to my terrible soldering technique at the time. I've improved quite a bit since then.

Heat kills chips; you can't heat a pin up for too long. Static, solder bridges, etc. are also common beginner mistakes.

Save the sidecar. You might need the shell, the connector, and other parts. Or you can even try to repair it one day.

used a wire to reconnect the pin on the chip that is normally grounded. It works uni-directionally again. That is a relief, but I really want to get it to work bi-directionally.
