My Maxdata Artist Harvard SL Pro laptop, dating from 1999, has this port on its back side. I have never seen this anywhere else, neither can I identify the little icon to its side. The size of the port is ca. 1×3 cm. What is it?

    Expansion or docking port... usually proprietary. – acejavelin May 04 '16 at 02:36
  • Icon means nothing to me, other than "expansion". Given how it looks like 2 parts, one upside down of the other, I wonder if it is PCMCIA Type 3, which was basically 2 slots. Or might be some other add-on, like RAM. If not PCMCIA, it doesn't look like a very widely used standard. – TOOGAM May 04 '16 at 02:45

According to the owners manual it's a Port-Replicator Port, used for a docking station or port expansion unit.

My German isn't good enough to interpret much more than that, but Maxdata has manuals, user guides, drivers, etc all available on their FTP site

  • Nice, that's true. It can be used for [Port-Replicator bars](ftp://ftp.maxdata.de/Accessories/Accessories%20Notebook/Datasheets/DB_Port_Replikator_D.pdf) with lots of additional ports. – Felix Dombek May 04 '16 at 03:02
