with a pair of single sided 5 inch floppy disk drive; a 20Mb Hard disk drive version was available towards the end of the product's life. The operating system was CP/M or a proprietary variant CP*, and the unit was supplied with a suite of applications, consisting of a word processor, spreadsheet, database and a semi-compiled basic programming language. The display supplied with the unit (both the Teleputer 1 and 3) was a modified Rediffusion 14 inch portable colour television, with the tuner circuitry removed and being driven by a RGB input. The unit had a 64Kb onboard memory which could be expanded to 128Kb with a plug in card. Graphics were the standard videotext (or teletext) resolution and colour, but a high resolution graphic card was also available. A 75/1200 baud modem was fitted as standard (could also run at 300/300 and 1200/1200), and connected to the telephone via an old style round telephone connector. In addition an IEEE interface card could be fitted. On the back of the unit there was a RS-232 and Centronics connections and on the front was the connector for the keyboard. The proposed Teleputer 4 & 5 were planned to have a laser disk attached and would allow the units to control video output on a separate screen. Spain In Spain the system was provided by the Telefónica company and called Ibertex, which was adopted from the French Minitel system, but using the German CEPT-1 standard, used in the German Bildschirmtext. Canada In Canada the Department of Communications started a lengthy development program in the late 1970s that led to a graphical "second generation" service known as Telidon. Telidon was able to deliver service using the vertical blanking interval of a TV signal or completely by telephone using a Bell 202 style (split baud rate 150/1200) modem. The TV signal was used in a similar fashion to Ceefax, but used more of the available signal (due to differences in the signals between North America and Europe) for a data rate about 1200-bit/s. Some TV signal systems used a low-speed modem on the phone line for menu operation. The resulting system was rolled out in several test studies, all of which were failures. The use of the 202 model modem, rather than one compatible with the existing DATAPAC dial-up points such as the Bell 212, created severe limitations, as it made use of the
