This was emulated through MAME. There's even a site that tells you everything you need to know about the Astrocade and emulating it, Bally Alley, and that site helped me get it running on EmulationStation on my Steam Deck, which is what I was playing it on. Bally Alley actually has the entire Astrocade library on it, including homebrew games that were released long after the console itself was discontinued.
I have seen Astrocades in the wild at Fallout Games, a Phoenix-area used-game store. Unfortunately, I failed to take advantage of them. Next time I see one I will definitely buy it even though I have it running on emulation.
