Oh I meant hypothetically - some of them did and some of them didn't since some of the cards pre-dated ProDOS. What I was trying to say was, if you wanted to do something where an RTC made sense, you would almost certainly have to buy extra hardware to do the something itself as well - it's not like the machine had as much as a serial port. I imagine the //e card gave a view of a nigh-impossibly tricked out //e, as would make sense for a //e that has an entire Mac as its 'peripherals'.
