    Thanks!

    All the original components go to the museum to keep the original machine together for historical purposes. As far as the original ITT full length CGA card goes there are a couple on Ebay.

    at ridiculous prices, as to be expected. Thanks anyway!

    I've seen worse. MUCH much worse.
    It is a mistake to think you can solve any major problems just with potatoes.

    They both accept offers so I would offer a low number. They have been there for quite a while. I personally would go for a 16-bit VGA card myself. As you probably already know some of them work in 8-bit slots like my Paradise VGA card. Here's a bunch for cheap and the seller accepts offers so you could probably get one even cheaper. Just need the metal bracket. Coming from the Ukraine, so may take a few weeks if you're not in a hurry.

    I have many graphics cards. I just though the ITT CGA card would be nifty. Not a big deal. I'd rather find one with the machine (and I am no particular fan of CGA). How CGA got offered with 286 machines is puzzling.

    Yeah, but as you know with the Xtra XP, it technically is a modified XT with a 286 CPU which is why I think ITT just kept everything the same in this system from their standard XT model. This is why I really like this system from a preservation point of view. It's an oddball, which is a good conversation piece in a museum and learning environment IMO. The fact you can flip between XT and 286 6MHz speeds by a key combination of CTRL-ALT-/ is kind of neat. I also like the fact this system has its own diagnostic ROM on-board by pressing CRTL-ALT-ESC and then type "H" for the diag menu. Those little weird touches make this system a tad more interesting to me.

    Also, I think CGA 16-colorish composite mode is the coolest. Have you ever seen Burger Time from Mattel Electronics in 1982 running in this mode? For a 1982 release this looked amazing and I still think it looks great even today. It's great DOSBox can now emulate this mode so we can all experience it.

    But that's not CGA. The Tandy 1000s, Sanyo MBC-550/555, PCjr and a few pre EGA third party cards could produce 16 colors. The IBM CGA card and presumably the ITT card can't. I can live with fewer colors if the resolution is higher. But at 320 x 200 I want at least that, 16.

    At 320x200 no. At 160x100 it can. As far as I am concerned it is CGA for the fact you need a CGA card (with proper monitor) to reproduce those wonderful composite colors. I am certainly no expert on the subject, but CGA had many secrets revealed through the years for sure. I am sure you have read this article where Trixter and company did the unthinkable with CGA.

    I'm still not convinced that wasn't in fact witchcraft.
