The keyboard unit was the pinnacle of our development effort. It was a visionary project, years ahead of its time. There has been some talk about emulating it; this would be a lot harder than emulating the Intellivision, because it where Intellivision merely loads a ROM, the Keyboard emulation must simulate the operation of a 4-track read/write cassette tape (2 tracks for encoded digital data; 2 tracks for audio). It's not as if that can't be done, but it's a tricky business. And there's also the issue of recovering the program material from surviving cassettes...it's no disaster if the audio track is scratchy, but if the digital data has degraded, then there's nothing to be done. Anyway, I'll be very interested if an emulation project comes to fruition.

So who is this "cashmoneymarvelous" eBay guy that won the auction? What's he gonna do with his prize? (Presumably it's in non-working state; the auction specifies "as is", and doesn't claim it works.)

Hey, I've got a Keyboard booklet for "Introduction to BASIC". I wonder what portion of $4000 that might be worth?
 

That's cool. I actually have the original brown Intellivision keyboard also, plus I have a complete set of all cartridges and cassettes made for it. And all of the games/programs are boxed and complete. I can't remember all of them because they are boxed up in the basement, but they include Crosswords 1 & 2, Geography, French, Jack LaLane, and more. Like I said, I know it is the complete set because I got them from a former Mattel sales rep. (The key thing is you have to have the Basic cartridge to make the cassette programs work, which I have also.) I even have one of the blank storage cassettes with the Mattel Elec label and logo on them. Pretty cool stuff, if I do say so myself...
