How to tell if JJOS was installed on used MPC1000?

I bought a used MPC 1000 and I think it may have JJOS installed, but I'm not sure how to tell. In the startup screen it says OS ver 4.63, but doesn't say anything about JJ.

Plus, tracks 57-64 are audio tracks, which I think is only available with JJOS installed.

I was planning on adding it myself when I bought it because I didn't think it had it, but I want to know before I pay for it.


NOTE:

This is the MPC 1000 I had listed in the buy/sell section, but I've decided to keep it, and I'm not sure how to delete the listing. Just wanted to let anyone know who may have been interested.


Thanks

as soon as u turn on thee power, it will say whuts installed, then whut OS is runnin off of it..........
nothin hard

Sounds like you have JJOS1 installed. If the OS1 password has been inputted then you will be able to save.
Latest OS1 version is 4.99L.

Thanks, I just saw a video on youtube showing jjos vs akai os, and mine looks just like his jjos ver 4.99, maybe its an earlier ver, but definitely a jjos. Thanks
