STOP! is a game written by Randall Lockwood and published by CodeWorks - Cursor, a company known for developing software for the Commodore PET. The game was released during the late 1970s or early 1980s, a period when the Commodore PET was a popular personal computer for both educational and home use. CodeWorks - Cursor specialized in creating games and utilities for this platform, often focusing on simple yet engaging gameplay mechanics.
The objective of STOP! is not widely documented, but it is believed to be a text-based or simple graphical game typical of the era. Given the limitations of the Commodore PET, which had a monochrome display and limited graphical capabilities, the game likely relied on text commands or basic visuals. The title STOP! suggests a gameplay mechanic involving timing, reflexes, or decision-making, though specific details about its rules or structure are scarce.
Randall Lockwood and CodeWorks - Cursor were part of the early wave of software developers who contributed to the burgeoning home computer market. While STOP! is not as well-known as some other titles from the era, it represents the creativity and experimentation of early game developers working within the constraints of 8-bit systems. Unfortunately, due to the limited documentation and preservation of software from this period, further details about STOP! remain elusive.
