Amiga SPICE is a program for simulating electronic circuits
Using the SPICE electronic circuit analyser on the Amiga.
For the original UNIX version of SPICE this output was meant for a line-printer so that the graph looked fine when the printout was turned from portrait to landscape orientation. Increasing the value of R1 has moved the graph to the left, meaning that the filter starts working at a ten times lower frequency than before. Without the interactive mode each of these changes would require a modification to the input file, which makes it a bit more cumbersome - especially for complex circuits.
