This program is designed to support both color and monochrome
    video displays with automatic video detection. It is designed for
    use on IBM-compatible PCs running MS/DOS 3.3 and above.
    The electronic codebook (ECB) has been tested on IBM-
    compatible PCs based on the Intel 80286, 80386, i486 and d
    Pentium processors. An 80386 or higher processor is
    recommended.
    
    The ECB documentation (located in directory 96ECBDOC)
    should be read first. Additional documentation on the survey
    components is contained in the following directories: 91ADULT,
    91CHILD, 93READY, 93SAFETY, 95ADULT, 95ECPP,
    96MANUAL. All documents are in WordPerfect 5.1. The
    documentation is formatted for any laser printer.
    
    The ECB program requires 40 MB (megabytes or million bytes) of
    available disk space on your C: drive. If 40 MB are not
    available, you will need to delete files on your C: drive to make
    room for the ECB program.
