Thanks for the great reply! Hmm, I could see why the ZX81 kit would be educational but perhaps not as exciting as the ZX Spectrum with its color graphics and game library. I'm not an expert on the Spectrum, but it seems like a very capable machine, with a lot of good games, some great contemporary books and magazines, and many fans here on HN. It looks like later models featured a capable sound chip. And it had a Z-80 CPU, allowing the +3 to run CP/M natively.
