EPE VIRTUAL OSCILLOSCOPE by John Becker
---------------------------------------
Everyday Practical Electronics, January & February 1998

This directory contains the software files for the EPE
Virtual Scope project. They can be used as a demo screen
version of the project, using an IBM-compatible PC loaded
with MS-DOS 3.1 or higher, QuickBASIC/ QBASIC, PS/2 mouse, EGA
or VGA monitor. Anything from a 386 upwards will be adequate.

INSTRUCTIONS FOR SCREEN DEMO VERSION
(no project hardware is necessary to assess these samples)

  Copy all files into your DOS (Qbasic) directory.
  Load QBASIC by typing  qb/l
  Load the file vscope.bas

  Edit Line 5 of the file:

    setupsim=0

  Change the 0 to 1 BUT DO NOT RE-SAVE THE CHANGE TO FILE!!!

  Run the program.

A display will appear, and your PC will start the set-up routine.
Initialisation is a once-only affair and will take anything from
6 seconds (Pentium 120) to 25 minutes (386). The bottom left-hand
of the display shows progress ("Making Sim file  xx of 25").

After set-up is complete, test the controls with your mouse.
Left-click on the box called LIVE. It should change to SIMULATE. The
Virtual Scope should then display sample sinewaves. Moving the mouse to
the right-hand column of the frequenccy setting boxes, left-clicking 
on any of them will load other simulation files. Click on timebase and
deflection controls too.
