Got a feeling that is a chinese import and won't have been made by Emach.

Provided you can figure out the DSP controller and it as enough memory to take the G-code you need then you shouldn't have any trouble working it.
How it performs will depend on what components the machine is made from and how worn, ie linear rials and ballscrews motors etc.
Often these chinese machines are built to price so they cut corners in key areas that cost most money so chances are it uses supported round rails in place of profiled linear rails, Cheap low power analog drives and could use lead screw not ballscrews. Thou doubt it as ballscrews are cheap in china and have been for a long time.

If there's no slop and it works for what you need then none of this matters and if there is any slop or worn out they can all be replaced easy enough.
Often the one thing people want to change on these machines is the DSP controller. It's not unusual to see folks wanting to convert to Mach3 or Linux Cnc because the DSP controller is limiting what they can do. This is a little more involved and will require a little electronics hardware and some wiring changes but again no big deal if needed.

Have fun watch your fingers.!
