Both, the 6x0 and 7x0 models have a cassette port, but the kernal does not
contain the routines to drive it. My copy of the service manual (in german)
says:
"Die jetzt gueltigen Betriebssystem-Versionen beinhalten nicht mehr die
Datasette-Betriebssoftware. Sie wurde zu Gunsten des Maschinensprache-Monitors
entfernt und soll als ROM-Modul verfuegbar gemacht werden."
(rough translation: The current operating system versions do no longer contain
the software needed to access the datasette. It has been removed in favour of
the machine language monitor and will eventually be made available as a ROM
cartridge.)
I don't know exactly with which version the datasette routines have been
removed for the CBM 600/700 models, but for the P500 this happened with
version -02. Since the kernals are quite similar, I would assume that this is
also true for the CBM 600/700 machines.
