This was caused by a bug in early OpenPROM 2.x versions (IIRC from 2.0 up to 2.3 inclusive).
SPARCstation 5 ought to have OpenPROM >= 2.9 and default to serial if no keyboard is connected, even with a framebuffer installed.
Now, if this machine is actually a Cycle 5 upgrade of an SS2 into an SS5, keeping the SS2 chassis, the serial ports are actually an SS20-like multiplexed port connected to the enclosure `B' port (the `A' port being the parallel port).
