Not sure about the asy aspect. My guess would be its an educational version. Many of the unopened copies for sale are just that, but I believe there is an upgrade path from educational versions as well.
Give avid licensing a call and ask them what the upgrade cost is for educational.
I would also contact the seller and clarify.
The math isn’t that hard.
1300 for a new version
300 for an upgrade to 8 plus what ever you pay for the “used” version, plus a bit of “will this work” cost.
I would be more inclined to look for used dongles online. They are pretty hard to spoof, and are easy to upgrade for that same 300 dollars. Pretty much any level of Avid can be upgraded to MC8 if you have a dongle. Again, a quick call to Avid support/licensing will clarify the cost.
