Sun SPARCstation IPX

The SPARCstation IPX is a small SPARC based computer in a lunchbox type case. It is the faster/newer version of the SPARCstation IPC. Compared to the IPC it can take up to 64MB of 72pin memory (instead of 48MB of 30pin) and has onboard colour graphics.

My machine was suffering from NVRAM failure when I got it (much the same as my SPARCstation IPC) but I have since replaced the chips battery. The machine also arived with one failed memory module which has been replaced. The system is configured with 64MBytes of RAM and an extra SBus SCSI controller.
