Dual CF adapter

[Matt Keys]

Ok, they have a cf -> PCMCIA card adaptor. But why not an adaptor that can take two cf cards at once? it sure looks like there is room, I have the perfect Idea on how to fit in the second one. Anyone agree with me here? I think it would be pretty darn cool.

you mean a sleeve that holds 2 CF cards? That would be great.

CF <-> PCMCIA and PCMCIA <-> CF adapters are extremely simple. The PCMCIA and CF use the same basic pin connections, and use the same type of protocols. Basically all the adapter does is map the pins through and physically adapts the size of the card. So electronically it does nothing - it is just like a couple dozen wires.<br><br>What you want would be very, very complex. The adapter would have to have a great deal of electronics packed into it. The Pocket PC would have to recognize the adapter itself as a device. Special drivers would be required on the Pocket PC that would somehow create 2 virtual slots, and then send that I/O traffic through the adapter, whose hardware would route it to the correct card slot. Performance would have to be degraded because you're forcing the I/O bandwidth of two cards through one slot, plus the data has to be processed by both the driver on the Pocket PC, and the hardware in the adapter.<br><br>So I guess all that is why you haven't seen one yet. <br><br>Dan East<br>

but you're working on one, right dan? right?!

[Dan East]

I automatically assumed one would want both cards recognized at once. I suppose a person could develop a mechanical switch of some kind to physically switch from one to the other, like an A/B switch.<br><br>Dan East

So the likely hood of having a wireless card in the top and a cf card at the bottom is slim? What if they were to make a wireless PC Card that has a built in 64mb card or something like that, would this complicate things or make them easier? The reason I bring this up, is because of online gaming with big games like PocketQuake which most people hold on a storage card.

Let me rephrase it this way. Say on the back of your computer you have a VGA connector. You want to hook two monitors to that single connector. That wouldn't be too bad if you just wanted to view the same image on both monitors. But here's the catch - you want to be able to show a different thing on each monitor at the same time. That would of course be extremely difficult, and require special software drivers and advanced processing by the "splitter". Roughly the same thing goes with making a single CF port into two ports.<br><br>Dan East

bummer, well that does answer my question though. Thanks.

I thougfht they had dual PCCard sleeves for the ipaq, or PCcard + CF sleeves... it seems that PC Cards are more cumbersome electro   engineering wise than CF.

There is a CF+PC card jacket for sale. Big as a brick, though.

[RwGast]

Really who sells it? How much is it?

[Luciano U. Werner]

I read about it at , but don't remember any specifics.

Sorry, had to edit. Now the link os "clicable".

here is one way to do it (I think)<br><br><br>It would seem you could use 2 CF adapters..<br><br>This is also kinda neat ..

that tv/fm tuner they've got for the ipaq now is apparently huge - i want to know why. <br><br>we had tv tuners for the game gear and they werent that big...
