Source-derived summary

Cassette 50 (released in Spain as Galaxy 50 - 50 Excitantes Juegos) is a compilation of games published by Cascade Games in 1983 for multiple 8-bit home computers. It was promoted based on the quantity of games included, all of which were programmed in BASIC and were of poor quality. According to the instructions, "the games will provide many hours of entertainment for all the family at a fraction of the cost of other computer games". The compilation was heavily advertised in home computer magazines. Buyers received a Timex digital calculator watch with each purchase.

In an interview, Matthew Lewis, the author of Galaxy Defence, said he wrote the game when he was 14 and submitted it in response to a small, anonymous ad in a local newspaper. He was paid £10 for his game, but he had to give up all rights to it. Galaxy Defence took 12 hours to code and the graphics were done by his father, Ernest Lewis.

Content

The games featured differed depending on the platform, all of which were written in BASIC. Some like Star Trek and Maze Eater appeared on all versions. Others like Lunar Lander were ports or clones of very early or popular games, while others were sourced from independent developers.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1983—that can be checked directly. The authority record carries competing date values—1983-01-01, 1986—which should remain separate until their references and qualifiers are resolved. Its strongest next move is a source search built around Cassette, video and game.
Editorial analysis

Why this record matters

“Cassette 50” is worth following because a concise public description often conceals a longer documentary argument. Here, Cassette, video and game provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q5049317. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1983.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
