The TELSTAR Videotex Service
1 Attachment(s)
I have just seen a few posts littered around this forum relating to V23 modems and Prestel etc. so I thought I would just introduce the TELSTAR videotex system for those that are not familiar with it.
The TELSTAR videotex system, developed in 2018, is a modern application that provides a simple 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. Full details of the system and how to connect etc. along with some videos showing how to connect with devices such as the BBC Micro, Spectrum, Apple II and a Tandata terminal, can be found at the link below. Enjoy! https://glasstty.com/wiki/index.php/...ideotex_System |

A “hello” in advance to fellow Micronet 800 users then. Sounds fun.

As mentioned by John Newcombe in this thread, the system can be accessed from a V23 modem on 01756 664433, though I haven't had a chance to try it yet - other than to confirm that it does appear to give the right sort of whistles when rung.

TELSTAR can always be accessed over the internet using a WiFi modem or whatever as the main system runs in a data cenre in london as close as I could get to Baynard House. Code:

Re: The TELSTAR Videotex Service
I have this accessible on the ZX Spectrum Next via the NXTel program, but it, along with the other Prestel services other than NXTel itself, doesn't work right as of yet. I'm hoping an update will sort it out in time, as currently it only loads small parts of pages on most occassions.

Re: The TELSTAR Videotex Service
Just so that I am understanding, are you saying that Telstar fails when accessed over the internet with the NxTel client?
I vaguely recall that the NxTel client relies on each frame being transmitted in a single packet. Telstar doesn't have this restriction and uses variable length packets. I imagine what you are seeing is the first packet returned from Telstar and the NxTel client is assuming that this is the frame in its entirity. Its just a guess though... |
