there really are very few form-factors that could be considered. here's where i've exhaustively evaluated all the ones that i could find: http://elinux.org/Embedded_Open_Modular_Architecture

the A20 computer card has Micro-HDMI and Micro-USB-OTG and Micro-SD. it's effectively the same as one of those USB dongle computers in that regard, so we're providing the option for people to pledge for a "cable kit". take care if you're going to source your own! make damn sure it's the right type, you want one that's "OTG Host Power" - many of the ones that you can find online DO NOT do the bidirectional power provision that you need.

The idea is that all the major ports etc will be covered by a shell going around the card.

Maybe they can sell this to F-16 squadrons. The F-16 loads its targeting information from a PCMCIA memory card. They're having trouble getting machines that can still talk to PCMCIA cards.

it's not PCMCIA compatible. the connectors and housings are still available - the problem is getting hold of the chipsets. yes there are a few processors around that can do PCMCIA, but they're rapidly going out of production nowadays. you might be able to bodge something together because PCMCIA is effectively just the ISA bus... anyway... digression... :)

Um, it has:

- Micro-HDMI Interface (for 2nd monitor)

- Micro-USB-OTG (bi-directional power)

USB-C would be great though

when the USB3 world stabilises - even intel can't get it right. also it'll be a while before GPL-compliant SoCs come out that have stable USB3 hardware. it's quite costly at the moment and the low-to-medium end tablet/smartphone fabless semi companies can't justify the cost.
