Teletext Receiver

[Ed Diego]

Hi,

How difficult would it be to make a circuit that can receive the British
teletext?

When teletext was being introduced about 30 years ago, I
made a teletext decoder, as described in Wireless World at
the time. It used ttl logic ics - about 100 of them!. The
3 pcbs were supplied by mail order. It had several presets
and was rather unstable. However, I got a great deal of
satisfaction from making it, and an understanding of logic
gates and teletext coding/decoding. === Sammy ===
