EMI BDI Instal

Tim, thanks for the response.
I am currently using an old IBM Thinkpad running deskNC, Dan's 2A
controller board to a home brew sherline CNC conversion.
My plan was to put BDI EMC on my main computer for practice and
familiarization.
and then procure an old computer for CNC use with EMC.
However, I think I will now get another computer for EMC.
What should be the minimum or desirable capability to run EMC?
Thanks again, Don
