Hello!
I'm searching a PC/104 board with an ARM Device supported by Keil. I found only some boards with a Cirrus CPU and embedded linux, but the Cirrus CPU is not supported by Keil, isn't it? Are there other expandable boards, i would like to have some expansion options for GSM Modem, more analogue inputs, relay outputs and so on... All this stuff just exists for PC/104. Maybe someone could give me some tips ;-)

Isn't PC/104 specifically a PC-style bus - so you'd only expect it to be available for PC-style processors?
"would like to have some expansion options for GSM Modem"
You just need an RS232 port for that!
No, PC in PC/104 does not have anything to do with PC as in x86 processors anymore. The bus is quite trivial, and very much used since it allows easy access to a lot of peripherials.
I have seen at least PPC and MIPS boards, and the following link seems to describe a ARM board with PC/104.

Hi, I found also only this one, but the Keil ARM-MDK and RL-ARM does not support the Cirrus CPUs? My problem is, that I would like to start 2 projects, a heater control and an irrigation control. For both projects I need an ethernet interface, a rtc and a lcd interface. So this would be my motherboard. Then optionally for both projects there should be a GSM modem available. For the heater control I need a lot of analogue inputs for PTCs, for the irrigation control I need a lot of relay outputs and only one analogue input 4-20mA to measure the pressure. Are there other possibilities than the pc/104 bus to realize such expansions? Unfortunately I'm a hardware rookie and I don't have someone who could help me. So for the first step I'd preferr to use some existing pcb's...
Please note that the PC/104 boards can be quite expensive. If you need your project to finish in a hurry, but want to produce few items, then PC/104 might be a good idea.
If your construction is expected to be built in large volumes, then it is normally better to design everything into your design. Then you don't have to split the profit with any PC/104 hw supplier.
Hi, thanks for your comments!
I found now a nice moduleboard: www.kristech.pl/.../index.php I think I will use this as my header board, and design some motherboards with expansion option through i2c, spi... Unfortunately the LPC2378 is not available at present :-/
