Sun also marketed these same machines under the "Netra" brand, without framebuffers or keyboards and preconfigured with all the requisite software to be used as web servers.
The SPARCstation 5 comes with an on-board AMD Lance ethernet chipset providing 10BASE-T networking as standard and 10BASE2 and 10BASE5 via an AUI transceiver.
The SPARCstation 5 has three SBus expansion slots which are typical of Sun computer equipment of this era.
The third of these shares its expansion backplate and physical space with a special AFX connector which was unique to the SPARCstation 5.
Sun used the same enclosure as the SPARCstation 4 for the SPARC Xterminal 1, which was, as the name implies, marketed as an X terminal, with no local storage.
