This has been sitting on my shelf for a couple of years, and I always just thought it was the red Demonstration Cartridge. But then today, while I was inventorying some stuff, I noticed that it actually is a Demonstration CASSETTE, presumably for the Keyboard Component (as implied by the directions on the back). And not only is it CIB, but it is still NIS.
Does this exist? I was poking around intvfunhouse.com, and ran across some links to a Sylvania Intellivision Keyboard Component catalog (as well as a Sylvania Intellivision pamphlet). The only stable link I have is to the Intellivision Gumbo page. If you click the third link for PlayCable and Sylvania catalogs, you'll see a page with the Sylvania pamphlet. Clicking it will take you back to intvfunhouse.com, and you can see the catalog and pamphlet. I can't find out how to access the page directly from intvfunhouse.com, but please post the stable url if you can. http://www.webring.org/l/rd?ring=intellivision;id=27;url=http%3A%2F%2Fhome%2Eearthlink%2Enet%2F%7Eclassic%2Dvideogames%2Fintellivision%2F
I'm finally getting around to posting the Blue Whale / Black Whale reverse engineering document. The document calls it Black Whale. But, in talking with Steve Roney and Bill Fisher, nobody there remembers any name other than Blue Whale for this device. In any case, there's extensive reverse engineering notes including schematics, commented disassembly, a user's guide, and pictures. All in all, about 100 pages of goodies. There's one little bit of disassembly on the 6502 side I haven't 100% worked out: The code that stitches the debugger into the KC's menu. The rest, though, is pretty thoroughly understood.
