Steam Multiplayer?
I'd like to play with my husband but there doesn't seem to be any guidance on how to get multiplayer going. I tried using Hamachi to use TCP/IP but the joining computer gets "game not found" when using my IP from Hamachi.

Suggestions?

If you're in the same household/network, you can try to use your local IP (not the public one); this way your machines can easily find eachother.
Else, when using any IP not directly assigned to your PC (router, VPN, etc), you'll need to use port forwarding.

Thank you for the suggestion! I tried using my local IPv4 (with Hamachi closed) and it did not find the game unfortunately.

You can also try IPX.
There's also hotseat (2 players on the same PC). The downside is that both players can see what the other is doing. It's still fun though. Have played ton of games in hotseat back in the day.

IPX has been deprecated for donkey's years now and no modern OS will be running an IPX stack so this won't work OOTB. Unless you're running SMAC on a win95 VM don't even bother with it.

OP, the bad news is that TCP/IP is unlikely to work OOTB either, because it relies on DirectPlay, which is again, you might've guessed it, a deprecated protocol. That said, it's straightforward enough to enable on modern Windows versions if you're ok with googling for the how-to.

It's true that the IPX protocol is old and hasn't been included by default since Vista, but it's still possible to install the protocol in Win10/11, if you download the files.

But, it may be easier to just use this IPX wrapper, which supports a bunch of games, including Alpha Centauri:
