Welcome to NTE - Electronic Component Database. There are five files needed to be able to use the guide, they are; NTE.001 NTE.002 NTE.003 NTE.004 NTE.005 These files must be downloaded individually and all must be present to use this package. I strongly advise that you perform the following operations on a hard disk with at least 4Mb. free space. With all five files available, use the DOS Copy command to combine them into one large binary file, the following command line worked for me with MS-Dos 5.0; COPY /B NTE.001+NTE.002+NTE.003+NTE.004+NTE.005 NTE.ZIP This will create a single large ZIP file that can be unzipped with PKUNZIP 1.10. Before unzipping, you may want to copy the original NTE.00n files to floppy diskette(s) to regain some hard disk space. After unzipping, you will probably want to delete the ZIP file as well. If you've successfully unzipped the created ZIP file, you're on your way, and you can run the NTE.EXE file. The files have been scanned for virus with McAfee's Scan 89. I hope you find the information included of value, Gene Lowry - Sysop Bigfoot's BBS Tucson, AZ
