Source-derived summary

Ladder is a platform game similar to Nintendo's Donkey Kong written for the CP/M operating system and made to be operated on the early Kaypro line of luggable computers. Ladder was written by Yahoo Software of Los Angeles, California. Along with Star Trek, CatChum and Aliens, Ladder was one of the games that came with the software bundle of the early Kaypro computers.

Gameplay

Since the Kaypro only has a text mode, the game uses letters, numbers, and symbols lined up to create walls and platforms, pits/traps, characters, trampolines and goals. The floors in Ladder are made of equal signs, and the ladders themselves are made of capital "H"s stacked on top of each other. The "lad" controlled by the player starts out as the letter "P" (lowercase "q" on left), the treasure is the dollar sign "$" and the ampersand "&", and barrels ("der rocks") are represented by "o"s.

The catchphrase of the game reminded the acolyte player that there are more ways than one to skin a cat. This referred to the fact that the minimized traverse of almost all levels could be enhanced by inventive utilisation of the game features, and the highest levels absolutely required it. These could entail (at the apex of the game) for instance jumping on a trampoline at precisely the right speed and point of impact to fall into one of the pit/traps, at the right timing that there would be no barrels passing for a sufficient interval.

Editorial summary

This brief starts where responsible research should: with the source description of “Ladder (video game)” as 1982 video game. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 246-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date 1982-01-01. The account is most persuasive where Ladder, video and game can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as 1982 video game. Its deeper value depends on whether names, dates, institutions and citations support that framing.

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 Dec 5, 2024. The linked authority identifier is Q6469305. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

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.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
