Acorn NetStation

[NCs, STBs & Prototypes]     [Computers] 

Introduction

In the mid-1990s Acorn worked for Oracle developing the reference design for the Network Computer or NC. The Acorn design became the NetStation. An NC was originally designed to run a web browser and to run applications in the browser window (e.g. using Java). As a result the NC has no local storage, apart from a smartcard which can be used to store user specific data.

The following models were produced:

The NetStation needs to load its configuration and programs from a server, it uses Bootp to discover its network configuration and then loads its applications.

Alternatively an IOMEGA Parallel Port ZIP drive can be connected to the NetStation and the NetStation can boot from the Zip drive. The Argo Zip Driver was commissioned by Acorn from Argo and is described in the Argo Zip Driver.

NetStation

My NetStation has Microlynx Topcat installed in the Ethernet podule ROM so it expects to discover a Windows NT4 server with Topcat installed. I have a copy of Microlynx Topcat, which was developed with Acorn's support to enable an NC to load its configuration from a Windows NT4 server and to use shared directories for storage, and have it installed on my NT4 server along with simple TCP/IP services. The NetStation searches for a Bootp server on power on, is assigned an I/P address and boots RISC OS from the server.
 
This NetStation has an Acorn 10baseT Ethernet Adaptor. Some other NCs have a v34 modem for dial up connections.
 
Here are some pictures:

Acorn NetStation Serial No.

NetStation serial no.

The serial number is on the bottom of the NetStation. The sharp-eyed reader will notice that the serial number is not the same as the serial number in the specification (below). This is because I have two NetStations and took pictures of one while getting the specification of the other. But they are the same.
