Re: Alternative IO cards

Seems to me that this kind of board would be of tremendous value to us.  As 
limiting as I find parports, I'd buy several.  We tried direct reading from 
and writing to a PCI card while at NAMES with the existing iosh and a little 
Tcl/Tk script.  Seems like the results were a bit less than satisfactory.  
But I'm sure that there is enough talent here to accomplish this.
