Notes by John Nelson:
Thank you for your interest in Eamon! Eamon was originally developed for the Apple II series by Donald Brown, back in 1977. It has since grown to 230+ adventures for the Apple II. The PC version was first converted back in 1985. I converted about 20 adventures before I stopped to see if there was enough interest to continue.
Of the original Eamon adventures, I converted many of the early games and then I concentrated on converting mostly my own adventures, since I knew the programs and special events better than I did any of the others.
The Eamon system for the PC has gone through some evolution since it was first converted. The very early editions were for BASICA and GW-BASIC. But these early Basics did not have any functions for trimming strings to their 'natural' length or for easily dealing with upper and lower case string comparisons. I had to write my own functions for these, which slowed the programs down. Back then we were talking 8086 processors at 4.77 MHz, so it was noticeably slow. (Almost as slow as an Apple II!) I later converted to QuickBASIC because it was a compiled Basic, which gave me my speed back. When QuickBasic 4.0 came out, it had upper and lowercase functions and functions for trimming strings of extra spaces - just what I needed! When DOS 5.0 came out, QBasic shipped with it. I adjusted (removed $INCLUDE) to permit QBASIC compatibility. But, since I need the $INCLUDE feature to save massive amounts of duplicate, code I had to abandon the QBASIC version. I created a utility program that will merge / remove $INCLUDE files so that someone could more easily convert their own to QBASIC.
The adventures are currently distributed with both source and executable files. The source code can be run directly using QuickBASIC (or if you don't have it, QBASIC after expansion.) The executable files will run on any PC, with or without QBASIC or QuickBASIC.
To install the Master disk programs and files from distribution floppies:
1. Insert the diskette in drive a: 2. from the DOS prompt (C:\> or D:\> etc. if you have multiple hard disks), enter A:\INSTALL a: c: MASTER (the a: represents the drive you are installing from, c: is the drive you want to install to. MASTER is the portion you are installing)
To install adventures from distribution floppies: 1. Insert the diskette with the adventures you want. 2. From the DOS prompt (C:\> or D:\> etc.), enter A:\INSTALL a: c: ADV#nnn (where nnn is the number of the adventure to install).
Note follow the above procedure for each of the ADV#nnn.EXE files on your diskette.
If you have the adventures on CD-ROM, you have your choice of installation options: either just drag the Eamon or EamonQ directory or use the INSTALL batch file from the DOS command line prompt. When you enter a drive letter other than A: or B: for source diskette, the installation assumes CD-ROM installation and installs all modules, not just a single module as the floppy version does. You therefore do not need to include the module name. If you us the drag and drop method, just drag the Eamon directory on the CD-ROM to your hard drive root directory in Explorer (or File Manager in Windows 3.1). Then change the read-only flag with the command attrib -r /s from your \Eamon directory at the DOS prompt. (A batch file called resetro.bat is included to do this.
