A Z80? Wow!

What numbers are on the devices bolted to the heatsinks on the middle board?

What you have is effectively a printer. HPGL is a printer/plotter control language and with the right (generic) drivers you ought to be able to simply print to your engraver from any graphics package. (Best results will be from vector graphics software).
A quick Google suggests that Inkscape will output HPGL.

Alternatively, if you want to control the machine as a CNC machine using EMC2 and G-code you are looking at a complete retrofit, replacing the motor drives and controller (but you should be able to retain the motors and encoders).
Deciding the best way to retrofit does require knowing what the motors are (stepper or servo). The fact that I see 4 tracks to each motor on the backplane makes me suspect stepper, but one could easily be an earth.

If all you need is 2 or 2.5d hpgl you can also use Tux Plot (google for it) it's a nice compliment to linuxcnc for machines needing hpgl output.
Also you may only be plotting just the corner because the machine's 0,0 coordinate is at the center of your workspace and NOT in the lower left like most machines. Tux Plot has a toggle that will overcome this problem for you.
The tricky part will be finding out the "z" axis command as each company seems to use a diff. command for z, once it's found out you can edit the z command in Tux Plot using the edit commands button.
Need any help email me..
