"Are you sure we need realtime? " It is my understanding that EMC is 'Realtime" thereby eliminating the slow serial port for machine control.
As Roland notes below, the machine accepts Step/dir signals converting it to using the parrallel port should be easy at worst. Somewhere in the EMC wiki is a paper written by some college kids that converted an mid 1990's teaching lathe to EMC control. They laid out a process you could easily follow for this unit to convert over if you so chose.
