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. [1] [2] Along with Star Trek , CatChum and Aliens , Ladder was one of the games that came with the software bundle of the early Kaypro computers.
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.
A platformer is a sub-genre of action video games in which the core objective is to move the player character between points in an environment. Platform games are characterized by levels with uneven terrain and suspended platforms of varying height that require jumping and climbing to traverse. Other acrobatic maneuvers may factor into the gameplay, such as swinging from vines or grappling hooks, jumping off walls, gliding through the air, or bouncing from springboards or trampolines.
CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors.

A personal computer, often referred to as a PC, is a computer designed for individual use. It is typically used for tasks such as word processing, internet browsing, email, multimedia playback, and gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in the late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people.
