The simple answer is no.
You can record a sync track on any multitracker quite easily. Just record the SMPTE or FSK (midi sync) tones on a track from the output of a time-converter 'black box.'
Actually syncing them is much more difficult. The decks themselves must support something called chase-lock, where the [servo] motors running the actual tape reels will instantaneously adjust their speed to keep up with the 'master' unit. As far as I know, no portastudios do chaselock. It would make them much too expensive.
Of course, they can be used as the chaselock master. But you still have to have something else that chases TO it.
