JJOX-kl 3.17

I saw this ad and the dude said “For Sale AKAI MPC 2500 With Black Pads, 128 MB Upgrade, 80 GB Hard Drive and JJOX-kl 3.17 Software!. This Machine is a beast and can do all pre-production aspects until you are ready to record and master" What is JJOX-kl 3.17 ?

Shit, I should of known that but i was hoping it was some unreleased special os or something.

Dude must have meant JJ OS-XL 3.17
