Star Traders is a simple text-based game of interstellar trading, where the objective is to create companies, buy and sell shares, borrow and repay money, in order to become the wealthiest player (the winner).
The current version of Star Traders runs under any modern Unix or Unix-like operating system that has a working C99 compiler. This includes, of course, Linux and Cygwin. Currently it can run in any one of eleven human languages. Historic versions are available for MBASIC, CP/M-80, CP/M-86, MS-DOS and Windows 3.1.
The original (and very primitive) Star Traders game was written by S. J. Singer in 1984 using Altair Basic. This was modified for Microsoft Basic (MBASIC) running under the CP/M-80 operating system by John Zaitseff and released on 7th March, 1988.
Star Traders was then completely rewritten in 1990 for the Australian-designed 8-bit MicroBee computer running CP/M-80 on a Zilog Z80 processor, using Turbo Pascal 3.01a. Essentially, only the name of the game and some of the ideas were retained in this version. Version 4.1 of Star Traders was released on 1st August, 1991.
In 1992, it was recompiled for the NEC Advanced Personal Computer (with 8-inch floppy drives!) running CP/M-86 on an 8086 processor, using Turbo Pascal 2.0. This version had colour added to it in the form of ANSI escape sequences; version 4.4 was released on 2nd August, 1993.
The next version came in 1993, when the program was recompiled to run on IBM-compatible machines running MS-DOS and ANSI.SYS. Turbo Pascal 6.0 was used for this. The ANSI escape sequences were slightly different under MS-DOS than under the NEC, in that the NEC supported a number of extra character attributes. In other words, the MS-DOS version looked worse than the one running under CP/M-86!
Star Traders was recompiled again in 1994 for IBM-compatible machines with VGA/EGA/CGA video graphics adapters. The output routines were recoded to use a “windowed” look. Borland Pascal 7.0 was used for this purpose, along with a number of text window manipulation modules. Version 5.4 was released on 1st June, 1994.
In 1995, Star Traders was completely rewritten for the 16-bit Microsoft Windows 3.1 graphical environment. Microsoft Visual Basic 3.0 was used for this purpose. Although completely rewritten, the original algorithms were reused from previous versions. Version 6.0 of the game was released on 15th September, 1995.
Star Traders was then to languish until almost 16 years later… when the game was rewritten once again, this time in the C programming language. Version 7.0 was released on 25th July, 2011 for Unix-like operating systems such as Linux, with subsequent releases to add features and correct bugs. Now you, too, can run this small piece of computing history!
