I did some research and here's what I got... I believe the TipS from 1995 is still the same one used today. It is possible that Mercedes is also using ZF 5 speeders.

Tiptronic was developed in conjunction by Porsche, ZF and Bosch. Porsche originated the idea, ZF made the gearbox
and Bosch responsible for the electronic control.

In 1995, a newer version called Tiptronic S launched. It offers fingertip control button mounted on the steering wheel spoke, thus allow the driver can to shift without loosing concentration on the road.
