Ceefax and Oracle were very useful services. Though Ceefax has really being replaced by the red button service. So not quite dead, just evolution.

whatever it was Digitiser on Four fell under, you'll always be remembered too

Technically that would have been Teletext. Whatever though, it was utterly brilliant at times. All written and mostly drawn by one man...

Ceefax was great for getting the TV guides, Football results/tables and weather etc. But that was before the days of the internet.

Digitiser was genius in 1K.

Every program or application from that era could be made with fewer lines of code. Also when you had to be efficient with coding.

It still boggles me how they got Elite in at under 32K, INCLUDING the memory used for the display.

I’ll repeat: 32K

The Elite universe contains eight galaxies, each galaxy containing 256 planets to explore. Due to the limited capabilities of 8-bit computers, these worlds are procedurally generated. A single seed number is run through a fixed algorithm the appropriate number of times and creates a sequence of numbers determining each planet's complete composition (position in the galaxy, prices of commodities, and even name and local details— text strings are chosen numerically from a lookup table and assembled to produce unique descriptions for each planet). This means that no extra memory is needed to store the characteristics of each planet, yet each is unique and has fixed properties. Each galaxy is also procedurally generated from the first.

However, the use of procedural generation created a few problems. There are a number of poorly located systems that can be reached only by galactic hyperspace— these are more than 7 light years from their nearest neighbour, thus trapping the traveller. Braben and Bell also checked that none of the system names were profane - removing an entire galaxy after finding a planet named "Arse".[7]
