SPICE RELATED PROGRAMS
These programs were written in GWBASIC, an old program that was distributed with some versions on DOS. They should run in most versions of BASIC. You can download the programs and documentation by clicking on the name below and then on FILE and SAVE AS. Save them in a folder on your hard drive.
File Name | Description |
