The TELSTAR videotex system provides a viewdata/videotext platform similar to those that were prevalent during the 1980s such as Prestel.

The aim of the system is to provide a Viewdata experience for anyone who is interested in how things ‘used to be’. Services in the past typically provided access via the public switched telephone network (PSTN) connection and this is indeed how Telstar works, however, Telstar also makes use of a simple internet connection for modern internet modems.

For anyone with an interest in early 8 bit computers, even for those of us in the UK, it is impossible not to recognise the importance of the Altair 8800. In this article I attempt to share my experiences with this awesome machine.

This code was developed from an idea by Oleg Mazurov and is presented here as a complete class that can be added as a tab in an Arduino sketch.
