second - do all the updates
third - verify the computer is running as you would like
fourth - go to linuxcnc and download the install script and install EMC2
fifth - verify the computer is running as you would like
sixth - if the computer is running as you would like you are done with the
install
if the computer is not running as you would like then peruse the
wiki and ask specific questions

you can use the serial ports
you can use usb
try some parallel port connections to see what EMC2 will do with them
Why do i want all this? I have been designing machines for almost 40 years.

The value of goods are expressed in money, while the value of money is
expressed in goods. Money and goods are clearly not the same things, but are
exactly opposite things. Goods are wealth which you have, while money is a
claim on wealth which you do not have. Goods are an asset; Money is a debt.
If goods are wealth; money is clearly not wealth, it is negative wealth,
maybe even anti-wealth. – Quigley, Tragedy and Hope, pg. 44 (emphasis added)
