This 555 Timer program was developed to quickly select
component values or analyze your timer circuits. All calculations
are approximations but you will find them to be suitable for most
applications. The design program selections will give you
standard component values and a potentiometer to adjust the
output to suit your needs. The program was designed to give the
Engineer quick results, and to save time in calculating out the
formulas needed to get a certain output. But to the beginner in
electronics this menu driven system and the Manuals "Theory Of
Operation" will help you to understand and use the timer right
away. For IBM PC or compatibles.

If you would like to purchase the compleate 555 Timer design package
with a compleate manual of operating instructions, theory of operation,
and example circuits and a system that will actually design a monostable
or astable circuit for you! Send $25.00 To:

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read:
