Update: recapped my grandfather's 1983 Macintosh and it booted to a sad face, not a desktop
Spent Saturday night at my kitchen table in Boise replacing 4 leaky caps on the analog board of a 1983 Macintosh 128k that my grandfather left me. Got the sweet chime and the beige screen, then a sad Mac icon with the error code 0F0003. Turns out the RAM chips were fine, the issue was one bad ROM socket pin I bent while prying the board out. Has anyone here had luck reseating those old sockets or should I just reflow them?

Did you check if the socket pin itself is still making contact or if the plastic is cracked around it? Those old sockets get brittle and a bent pin can sometimes stretch the contact so reseating alone won't fix it. I'd try a thin needle to gently bend the pin back and test with a multimeter first, then reflow only if the joint looks dull or cracked. Reflowing all of them is safer long term but those traces lift easy if you get too hot, so keep the iron around 650 and don't linger.
