Cubase SX on new licenser?

So I pulled an old G4 mac out of my closet and want to run my old Cubase SX install on it (for nostalgia purposes). Before I go through the trouble of digging for install discs and interfaces and all that, does my Cubase 10 license still support SX or do I need a second licenser? I’ve had this “new” licenser since Cubase 4 and it still held the SX license for years but I don’t know what the new licensing software does to it these days.
