I have updated TELSTAR now. It includes TELESOFTWARE :D .

glasstty:6502

The protocol implemented on TELSTAR works with Commstar for programs up to 25 frames. I have yet to implement 'Zero' routing which isn't much to do and this will allow many more frames.

The test 'Hello World' program hosted at the moment is a tokenised BASIC program and although it is small, it tests the system reasonably well. I will undertake further tests for binary files when I get chance.

The routing engine has been updated to be similar in the way Prestel worked, however there are a couple of very minor bugs which I will sort out. Also I haven't yet implemented the 'Master Page' navigation stuff where IP's had the three digit master pages. At the moment you end up back at the main index.

Currently there is only one service running (it will handle multiple connections), it is named MONTY. It is running out of a data centre in London.

Thanks go to the guys over at the Software thread viewtopic.php?f=2&t=15047&p=202811#p202811 for helping me with protocol issues. For now, I will continue posting updates here until told otherwise.

New Content from Reuters and Better Navigation

Post by John_Newcombe » Tue May 15, 2018 6:26 pm

Hi All jus a quick update. The service has been updated and now includes a few new facilities including a Teletext page import facility, better routing with a Prestel like routing map and Reuters content.

Content is still quite weak in places, and the style is a tad boring, especially the intermediate frames, however, I am sure it will evolve as time progresses.

Next task is to develop a cross platform page editor in Python.

I have added more content, in particular Government content from the Office of Rail and Road, and Highways England, I can now show up to the minute (well 10 minutes) details of road and rail delays.

Full details and some screen shots here... https://glasstty.com/wiki/index.php/Int ... ata_system

How are you connecting and at what speed?

The recommended speed for Telstar is 1200 or 2400 full duplex. Any faster and the flash messages can be missed and the experience IMHO is too 'modern'.

Bye bye Monty hello Currer, Ellis and Acton

Telstar now moved to new servers and migrated to Python3. There are two/three servers available and each can service multiple clients, so that should keep it fairly future proof.

The servers are on the same url but with different ports, e.g.

glasstty.com 6502
glasstty.com 6503


There is a third server which is used to test updates etc. this is on port 6504.

The Telstar system names are CURRER, ELLIS and ACTON respectively (get it?).

There are still a couple of outstanding routing bugs, I will try and sort these asap. Content will get a little tidy also and coming soon (hopefully), is a gateway to an adventure game, in fact THE adventure game, a port of “Adventure” from the original 1977 FORTRAN code by Crowther and Woods. More on that later.

Enjoy!

All you need now is an interface to read and post to stardot forums.

Half way there then. I hadn’t spotted that but to be fair I have visited for a free weeks. (I work on ‘getting old weeks’, so error margin is high).

I am a little disappointed that this doesn't work in terminal. The Master Welcome guide says you need to buy an Acorn Prestel adapter to use Prestel, which comes with a self-dialing modem and a ROM. Still, commstar works fine on the Master.
