[App_rpt-users] Small System Recommendations

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.
