How to avoid tin whiskers?

How do you avoid tin whiskers when repairing Amigas? Do I just use a leaded solder or what?

Since the Amiga predates that dumass lead free solder, I'd stick with good ole 60/40 rosin core solder.

For classics you probably need to use leaded solder anyway. Don't know if the lead-free stuff is compatible. Before rohs, leaded solder melts at lower temps so other board materials are workable at certain temperatures. Higher temp lead-free solder could burn the thing due to higher temps to melt that. Newer rohs boards etc. Can be worked at the higher temps.

Lead is your friend.

btw: Mixing RoHS and leaded solder is no good idea - usually you stick with what you got.
