I have 5 of the Neoware CA22 systems on the way, so wish me luck! Robert N5QM On Mon, Jun 24, 2013 at 7:39 PM, George Csahanin <george@dyb.com> wrote:
I have standardized on the Intel D945 motherboard in a M200 case from Mini Box. 1GB RAM and a 256MB CF and use Limey. Limey can be customized for other motherboards. The power supply is tricky. I found the cheapies convert the 12V in to 5 volts. But they tend to take the 12 volts in and make that the 12 volts for the motherboard (P4 4 pin connector) Any wiggle on that 12 Volts and the computer does really crazy stuff. Mine would just shut down. So thru trial and error I found the PICO PSU 60-WI 60 watt power supply. The input can go down to about 7 volts and the 5 and 12 volt supplies are steady. Runs very stable.
One drawback of this motherboard is the USB system. If you use SimpleUSB, it's great. USBRadio, not so good. Lots of audio interruptions that last miulliseconds. For voice, not a problem. But if you're using it to decode PL and squelch it just will not work well. I'm told other motherboards (read: non-Intel) would be better. But I have about 7 of these now, not going to change. But the printer port is important to me. So I didn't need to hack the USB Fob I use pp signalling. Getting ready to add remote base to it in the coming weeks.

All,
I am looking for recommendations on small, preferably inexpensive, systems that are capable of running on 12v to take advantage of the redundant power systems at our sites.
I would like it to support at least two nodes running simpleusb as I don't need the DSP processing capabilities. The idea is that these systems would be connected to a port on an existing controller.
I expect that HP thin clients are going to be my best bet, but there seem to be many different models so I don't know where to begin.
Suggestions or thoughts?
