OK, that is reasonably close to what I'm getting, considering 
the greater I/O points.  I can run up to 10 KHz with one of my 
UPC or USC boards with on-motherboard PP on a 600 MHz pentium 
II.  I can go to 5 KHz with 2 UPC's, so that's 8 axes 16 digital 
outs and 31 digital ins, on the same machine.  I can probably go 
to 10 KHz with 2 boards with a PCI parallel port and a little 
faster CPU.
