Hi-Res Adventure #1: Mystery House

Online version of Hi-Res Adventure #1: Mystery House for Apple II. Mystery House, released on 5 May 1980, is the first graphic adventure game ever made and the first game by Ken and Roberta Williams: Roberta designed and drew it, Ken programmed it, and they sold it by mail order in a ziplock bag. The player enters a large old Victorian house where 7 other people are hunting for hidden jewels, but the door locks behind them and the guests start dying one by one. Every room is a monochrome line drawing with the objects drawn right into it: whatever the player picks up vanishes from the picture. In 1987 Sierra released it into the public domain.

Apple II Computers

Online emulated version of Hi-Res Adventure #1: Mystery House was originally developed for the Apple ][ (Apple //), a family of home computers, one of the first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak, manufactured by Apple Computer (now Apple Inc.), and launched in 1977 with the original Apple II.
The Apple II became one of several recognizable and successful computers during the 1980s and early 1990s, although this was mainly limited to the US. Through 1988, a number of models were introduced, with the most popular, the Apple IIe, remaining relatively unchanged into the 1990s.

All the machines in the series, except the //c, shared similar overall design elements. The motherboard held eight expansion slots and an array of RAM sockets that could hold up to 48 kilobytes. Over the course of the Apple II series' life, an enormous amount of first- and third-party hardware was made available to extend the capabilities of the machine. The //c was designed as a compact, portable unit, not intended to be disassembled, and could not use most of the expansion hardware sold for the other machines in the series.
All machines in the Apple II series had a built-in keyboard, with the exception of the IIgs which had a separate keyboard. Apple IIs had color and high-resolution graphics modes, sound capabilities and a built-in BASIC programming language.
