Nearly ten years ago in 1994, Sun microsystems introduced the SPARCStation Voyager (ss240). This computer was a Sun4m architecture, powered by a microSPARC II processor. It is a very compact computer, behing a hybrid between a desktop and a Laptop. It has the footprint of a very compact workstation with a builtin color LCD display, PCMCIA and InfraRed ports with a 2"5 SCSI harddrive. I have seen one at the CCC in Berlin, runing Debian GNU/Linux but the InfraRed and PCMCIA ports are not supported. Its datasheet is actually very impressive:
