SKEM 1.0 Installation Instructions The install program will ask which drive you wish to install SKEM 1.0 on. It then will create a subdirectory of SKEM and copy all the files from the floppy to that drive's subdirectory. After copying all the files the install program will execute the MAKE_PTR.EXE program. The MAKE_PTR will read each of the .SCR symbol files and create a laser printer bit-map file (.PTR) of that symbol. After the install program is finished, you will be returned to DOS. To run SKEM 1.0, just type in SKEM and hit the ENTER key. Enjoy......
