Some how I missed this thread last spring, but it's a very interesting read, I love the speculation in the article, and I notice some errors, like a lack of the 160x192 graphic mode, and what's this VCR socket they refer too? Are they talking about the monitor port by mistake?
Looks like they thought the monitor out would also hook up to an old VCR with the right cable.
Well, it certainly can hook up to a VCR with a monitor cable, but just for recording "video" from the Atari. But not for data transfer or feeding video to the Atari. Though if a VCR is hooked through an Atari cassette deck it could be used for data transfer, with a bit of manual control on the VCR end. (I'm referring to a DIY mod everyone, to an Atari recorder)
