Using The CD-ROM
------------------------------
The 1990 Summary Tape File 1A software was developed on a COMPAQ Deskpro
286 with 640K RAM operating under MS-DOS 3.31. The software was compiled
with Clipper (Summer '87). There are no special display requirements.
For direct access to the data files, one of the many software packages
which recognize the dBASE III Plus (.DBF) format will be very useful.
Users of other types of systems, such as the Apple Macintosh, have access
to the files through support for ISO 9660 CD-ROMs. Please note that the
retrieval software will only run on IBM-compatibles operating under MS-DOS.
Type GO at the DOS prompt and ENTER. Example: L:\>go
