What version is it?
How old is your machine?
Some versions work better on the older machines while others can work on the newer machines.
You will need a full size keyboard.
I hope it is a good disk with nothing missing. Do you also have the original version disk? What version is that? Just in case it is a very old EZTRAK with a older version of DOS onit.
ALL of the newer versions have some bugs in them. Version 5 is probably the least buggy of the newer versions.
Version 6 and 7 could do engraving.
Version 7 (maybe 6 also) could import DXF files but with limitations.
