=== LASI System Installation from Networked ZIP Files === LASI 5.1 requires an 80386 or higher and VGA graphics or higher. If you do not have these you can install the LASI CAD system, but you will not be able to run the main drawing program. The files of the LASI CAD system are compressed in a single ZIP file LASI51?.ZIP, or have been broken into two groups for better downloading. The group files are named LASI51?A.ZIP and LASI51?B.ZIP, where "?" represents the revision number digit (0-9). They are compressed using PKZIP 2.0. To install, follow these steps: 1. Create a subdirectory named "\LASI5" on your hard disk, directly under the root directory. 2. Copy the files in LASI51?.ZIP or LASI51?A.ZIP and LASI51?B.ZIP into the \LASI5 subdirectory. 3. Using PKUNZIP 2.0 or similar program, uncompress the files. You MUST have the files from BOTH groups, and they MUST have the same DATES. 4. Make the \LASI5 subdirectory the default directory. 5. Run the help program LHI.EXE by simply typing "lhi". Read the "Basic Information/Installing LASI" help topic to complete installation. === Subdirectory Installation of TUTOR.ZIP, CHARS.ZIP and ICONS.ZIP === A tutorial drawing and Windows icons have been included with LASI. The tutorial is a small opamp IC layout that may be used when first learning LASI. After the LASI system has been installed, the tutorial and the icons may be installed by following these steps: 1. Create a subdirectories under the \LASI5 subdirectory named "\LASI5\TUTOR", "\LASI5\CHARS" and "\LASI5\ICONS" on your hard disk. 2. Copy TUTOR.ZIP, CHARS.ZIP and ICONS.ZIP into their directories. 3. Run PKUNZIP or similar program on TUTOR.ZIP and ICONS.ZIP and uncompress these files in their directories. === Running the Tutorial === 1. Make the \LASI5\TUTOR subdirectory the default directory. 2. Run the batch file TUTOR.BAT by typing "tutor". This will reconstruct the drawing and run LASI. The layout of the IC will be drawn. Press F1 for LASI help or F2 to start the tutorial.
