The old Mac community is excellent, maybe even one of the better retro hardware communities. It's filled with people who are very smart and making cool things.
There's definitely a higher barrier to entry with old macs compared to old PCs, but the community has done a good job lowering those barriers over time via devices like the FloppyEMU.
I should have restored an SE/30 like you, but instead I fixed up this[1] Mac, it really is the ship of theseus in computer form.

Right now I've got a Plus I'm working on fixing up. Compact Macs are addictive, you've been warned ;)
