Teletext Adaptor and Tuner from Microtext Ltd.
Teletext offers one-directional data transmission, broadcast via an television signal (it is a ViewData like system).
Required UHF/VHF Decoder (Tuner)
The Microtext adaptor does not include a UHF/VHF decoder. Instead, it requires a composite video signal - which can be obtained from following sources:
- From the Video Out socket of a Video Recorder (if one does own a VCR)
- From the Microtext's Tuner (which was sold separately, for users who don't own VCRs)
Telesoftware
Unknown if the software included support for downloading Telesoftware? (hardware-wise it should be no problem since Telesoftware is transmitted as normal Teletext pages).
