I have been wondering about that for a long time. Could you please place a ruler next to it and get a ballpark depth measurement? I just did this with the PCM-5822 and it's well under an inch, even with the CF socket sticking out the bottom. It measures about 1/8" shy of an inch from the bottom of the CF socket to the top of the highest heat sink. Most of the board is much slimmer, less than 3/4 inch (God I hate this, I'm a metric person living in a country in denial of the benefits of metric). BTW I don't agree that having it all on one board is just too thick, it could be slimmer, it's just the way that they design the boards that is the problem. I say this because some time ago I had a CardPC carrier board that had dual PCMCIA onboard, it was slimline. If their goal in PCB design was slimness, they could find a way. If you stack two pcmcia cards on top of each other, that's your thickness. The carrier board that I used only added that amount of thickness (two stacked pcmcia cards) on the PCB surface). It had no space in between the cards, and the "housing" for the cards was thin aluminum. Unforrtunately the length and width was undesireable, the carrier board is now obsolete, and it had no multimedia capabilities. It SHOULD be possible to create a multimedia SBC with single pcmcia slot that is no thicker than the PCM-5822 or perhaps even more slimline. Some day I might try designing my own. > One of the reasons that I changed from the EM-350 to the PC-2553 is > the depth of the board.

The probem is that there are 104 conductors between the CPU and the peripheral card. If you find a "clean" way to do this, please let us know. I started to make my own cables for this a few times, but gave up after 60 or 70 of the necessary 208 solder connections. I know that others have done this successfully, but either way I look at it there is no way to streamline 104 conductors. Sommebody needs to build a special high density cable for this. The standard IDC cables are too thick. If you look at the density of SCSI cables and LCD connection cables, it could be a lot smaller, but needs to have the funky 104-pin connectors on the ends. If anyone is in the cable business, please build and sell us these PC/104 extensions! > The 10bT connection on the EM-350 never work anyway (without 12V that is) > So my main use for the PCMCIA was my WLAN card.
