All,

"Thou shalt have only one CPU on the PC104 stack". Is this dogma 
rooted in reason?

I need a pulse counter board. Technologic does not make one. Other 
companies do, but they are power hungry. I'd like to use a second TS-
7260 on my stack doing brute force counting on its DIO1 inputs. I 
would welcome answers to:

1) Is this possible?
2) What would be the best way to transfer the final counts from the 
dedicated counter CPU to the main CPU?
3) My counting program produces counts that are within 1% accuracy 
when counting input pulses that are 20 kHz. But the counts are not 
consistent. I assume the lack of consistency is becuase of 
preemptive multitasking. Is there a way to guarantee my counter 
process would never be preempted from the dedicated counter CPU, or 
would I have to not run Linux on the dedicated counter CPU?

Thank you.
