AFAIK Roadstar II wheren't there until the 80s. They where followed by JEMs, RGs, S, Radius etc... so my guess is that your guitar is about 20 Years old (maybe less). If I am not mistaken some Roadstars even do have the
pointy headstock, that would make the guitar a least 80s one.
Have a look at
Blue Horizon, maybe you find some pictures there (and just try all the Roadstar-Pics).
Or even better at:
Ibanez Register, loads of pics there... go to 'Gallery' for different models.
