The Remote Annex 4000 complies with the Ethernet Revision 2.0 or
the IEEE 802.3 specifications using standard Ethernet 10Base2 (Thin),
10Base5 (Thick), and 10BaseT (twisted pair) as the physical medium.
The Remote Annex 4000 also provides a parallel printer port for
attaching printers with either a Centronics or Dataproducts interface.
The Remote Annex 4000 main logic board (MLB) comes with the Intel
80486 SXLC2 clock-doubled processor.
The MLB supports an integrated 10Base2, 10Base5, and 10BaseT auto
sense Ethernet connector.
