"Acorn Computer systems contain a Teletext/Prestel standard
VDU which can drive both colour and monochrome monitors. The System 3 above
connects via a serial interface port to an integral Modem and functions as a
Prestel terminal. Data may be received from Prestel and stored on the
mini-floppy disk for subsequent processing and display. Files may be created on
the system using the Prestel screen editor and disk storage. When correct,
Information Providers may transmit these files to the Prestel computer using the
bulk update facility.
The Prestel software contains powerful editing commands,
user number storage and auto telephone dialling. It is mainly written in BASIC
and can be modified to meet specific user requirements.
Printers, Teletypes and further VDUs may also be connected
to Acorn computers which support one or two mini-floppy disk drives. When not
connected to the Prestel computer the system provides powerful computing
facilities including a wide selection of languages and peripheral devices.
