Bought 2500 from a guy on Offer Up. I have never used JJOS before, this MPC has it. I told him no problem. I looked it over, tried it out, everything works great, so I made the purchase. There is no password for this OS included. Will it let me save anything without the password?

If he's referring to one of the 'paid' JJOS, and he originally paid for the password and entered it into the machine, it will be forever saved inside the machine, so saving will always be enabled for the version paid for. But 'JJOS' could mean one of several JJOS versions, one of which is 'free', no password required. In fact most people will be referring to the free version unless they state otherwise (IMO).

It’s version XL 3.59. Anyone have a link where I can purchase a new password?
