The 5I25 should be able to support that breakout easily if you can actually determine the parallel port pinout. Unlike even a parallel port, the 5I25 can support completely arbitrary pinouts (any pin can be input or output) as long as the ground pins dont move, the pinout is possible Peter Wallace, Mesa Electronics ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
