I'm looking at an ad for "CARDIO 386," a PC in a thick card a little bigger than a credit card. It has a 236-pin connector with a full AT bus, VGA interface for video or LCD, IDE interface for hard disk, 1 parallel, 2 serial, keyboard, mouse and floppy interfaces. Up to 256K Rom and 4M DRAM. I don't see built-in SRAM or battery, but they have SRAM and flash cards as well as a PCMCIA interface. The point is that it's what developers and their tools are used to. You could run regular PGP on it, for instance. (That reminds me: does anyone know whether automatic teller machines are PCs inside?) S-MOS Systems of San Jose, CA.
