Sun Microsystems 3/60system. Well systems (I've got eight!) these systems have been sitting in a warehouse for the past year or so, most have some memory and use standard 30 pin parity simms they power up ok and run with a serial terminal connected to port A. they then try to network boot.
They get through the power up selftests and then go on the hunt for an operating system. I've tested the boxes with a terminal connected to serial port "a" with no problems. The cases are a bit grubby, and will need a really good cleanup.
On the back are the keyboard, ethernet (BNC and AUI), serial ports, SCSI and video connectors. Also the diagnostics L.E.D.s and switch.
