It’s a shame what’s been happening with Arduino and their legal battles. Not a pleasant thing at all. However, it’s good to see a new brand emerge that’ll hopefully establish itself as the number one name in DIY boards.
Go for it Arduino!
But I have to ask why? It isn’t like there’s anything you can do with a ZX81 that I can’t do elsewhere, and so I constantly battle with myself, sometimes wanting to get one, and other times deciding that it really is a bad idea and I just wouldn’t use it, and that is really a lot closer to the truth as that happens with stuff I buy, I’m sorry to say.
I also sometimes think about some of the things I could do with one, and then try and use an emulator, and don’t really get into that and that also tells me that getting an actual ZX81 would be a bad idea. Even though I think they’re awesome.
