The JavaStation-1 is based around a 100MHz MicroSPARC CPU, similar to that used in the SPARCstation 4. It is housed in the same case as a StorEdge UniPack disk. It uses some of the components found on the SS4 (Lance ethernet, CS4231 audio, TCX graphics), but replaces the Zilog serial ports with an 8042 for the keyboard/mouse and a 16550 for the serial port.
This JavaStation-1 is a model JJ-32 - the two 16MB SIMM's are visible with the top removed. Rear ports are (left to right): mouse; keyboard; video; network; serial; audio.
