Hello, my first post here.
I recently picked up a MPC1000 with JJ OS1 (ver 5.00).
I cant find much info on this version and to my understanding it has been discontinued.

I was wondering on how to upgrade to the current JJ OS?
Also if I would have to purchase it new? or if this OS would still be considered an upgrade?

For future reference for others, the price is still $123.

You guys still think the upgrade is worth it?
