Ariadne is a modern Zorro-II Ethernet card for the Amiga models A2000, A3000 and A4000. It supports both Ethernet standards 10BASE-2 (Thin Ethernet) and also 10BASE-T (Twisted Pair). You can easily switch between these two hardware protocols via software. There are 32 Kbytes of buffer RAM on board and also an option for a boot EPROM.
Additionally, Ariadne offers two extra parallel ports to connect a printer, a scanner, or any other peripheral device. Beside a normal parallel driver we also supply two network drivers for these parallel ports: One ParNet driver and a SANA-II compatible PLIP driver, called liana.device. You can therefore install two peer-to-peer connections to smaller Amiga computers without any Zorro-II slots.
The network drivers for Ethernet and the parallel ports are both SANA-II compatible. Therefore every network software package based on Sana-II can be used with the Ariadne. For example, AmiTCP or Envoy which is included with the Ariadne. Envoy offers FileSystem import and export, network printing and multi-user support together with an easy installtion and configuration procedure.

JP1: Enable Boot ROM?
Off: Set to disable autobooting (default).
On: Set to enable autobooting from an on-board EPROM.
Connectors
LED Connector (6-pin header)
Pin 1: (LED 1) Twisted pair MAU link status
Pin 2: (LED 2) Transmit status
Pin 3: +5V

Parallel Port 2 (26-pin header)
Note that these connections are set up for use of a standard
26-pin
header to a DB25 female mounted on a slot cover. This should
be a
standard part, but check connections before using it.

Both Ariadne parallel ports have the same pin-out as the
standard A4000
parallel port.
