Morley Electronics produced a Teletext Adaptor expansion for the BBC Micro and the Electron. Since the BBC Micro has the Mode 7 display capability, the model aimed at the BBC Micro merely provided the content reception capability needed to receive and decode Teletext signals, connecting to the user port and power supply. However, the Electron models provided both display and reception capabilities, doing so by routing either the RGB or UHF signals (depending on the model) through the unit in order to introduce the Mode 7 output produced by the unit, also connecting via a cartridge. The Teletext display capabilities in the Electron models exceeded those of the BBC Micro, with one reviewer noting that the enhanced capabilities permitted "black text on a coloured background, something I've always wanted to do on my Beeb". The UHF model of the Electron adapter also supported overlaying of Teletext onto video and framing of video.
