Calc 2.15 Electronics CALCulations
Documentation
Calc 2.15 was tested on a stock Tandy 1000TX
with Tandy 16 color graphics, an XT clone with
EGA graphics, and a Mac running SOFT AT.
----------------------------------------------
Calculations for Electronics
Scope: Basic Fundamentals
--------------------------
The basic fundamentals of operating Calc 2.15 are:
(1) Use a mouse with a recent mouse driver,
Logitech 6.00 or higher version of Driver
Genius Mouse 9.06 or higher version of Driver
Or Microsoft MS Mouse Driver from 1991 or later
(2) If you do not have a mouse then the keyboard
will work just fine. F10 selects the top menu.
Other function keys are highlighted at the
bottom of your screen for quick function select.
(3) You need to have a color video card and monitor
for your PC/XT/AT/386/486 or better clone.
You need Soft AT if you want to run it on a MAC.
(4) Calc 2.15 will emulate a coprocessor to do its
calculations but if a coprocessor is installed
Calc 2.15 will use it.
(5) Without a mouse, menus are enabled with F10.
Items in top menus are selected using the left
and right arrow keys(also known as left and right
cursor keys). The return or enter key selects
the top menu item. The top menu item will have
a box open up with all the possible selections
under that item. Use the up and down arrows(up
and down cursor keys) to select an item in the
box. Press the return or enter key to select
the highlighted item in the box. <OR> To select
another box to open while the menu is still
active, press the left or right arrow(cursor)
keys. Then select the item in the box that you
want using the enter(return) key.
NOTE: Menus are disabled when you are prompted
for data entry in calculation or
conversion functions. Menus are always
enabled when a text display(help or
explanation) is in th user screen area.
(6) With a mouse, use the mouse to select the top
menu item. When the top menu box opens use
the mouse to select the function. Key usage
as in #5 above is still valid.
(7) Math usage(VERY IMPORTANT):
To input a value that is in scientific notation
such as 1.546 times 10 to the power of -3 use
1.546e-3 notation. The number 1.546e-3 is in
decimal form 0.001546 units. For European
users, this program uses . as the decimal in
all input variables. A comma (,) is not used.
Please be aware that I will make a European
version available if there is a sufficient
number of European regtrations. Programmers
who wish to make a native language version
of this program may submit their request to do
so in writing to:
Kenneth Otto
P.O. Box 8312
Cocoa, Florida 32924-8312 USA
Licenses for use of the code in this program
for the creation of native language versions
shall only be granted by Kenneth Otto.
The current price for foreign licensing will
be discussed in writing to those who submit
a request.
(8) The bottom menu, or status line, has the hot
keys for EXIT, text info screens, or top menu
select. Currently, F1 is exit program,
F10 is top menu select, and the others shown
are for text information screens to be used
by novice technicians when studying electronics.
---------------------------------------------------
Scope: What is does
--------------------------------------------------
(9) This program makes conversions
from RMS, peak, and peak to peak voltages
to RMS, peak, or peak to peak voltages.
(10) This program calculates Resonant Frequency
from L(inductance) and C(Capacitance) values.
(11) It uses 11 digit accuracy for PI in
calculations involving PI. (Resonance)
(12) It calculates the square root of two for the
AC voltage conversions eliminating errors
from approximations. (Ac conversions)
(13) It uses extended real numbers for precise
calculations.
(14) It finds voltage, current, or resistance
when the other two values are known.
(Ohms Law)
(15) It finds power, voltage, or current
when the other two values are known.
(Power Law)
(16) It has a registration code that versions
2.00, 2.01, and 2.02 did not have.
===================================================
Scope: How I conceived Calc 2.00, 2.01, 2.02, 2.10
---------------------------------------------------
I wrote 3 versions of this program and sent them
out locally to bbses. Nothing happened(no users
registered). I had included mono graphics support
and 40 column support in those programs. But they
were perhaps to basic to be understood. At that
time the program was all text driven.
This new program was designed to be a lot more
user friendly, and it is. It uses Turbo Pascal 6
Menus. Hopefully, you will like it and register
it.
NOTE: This program does not support mono graphics.
Persons to Thank:
----------------
(1) My Pascal Teacher.
(2) The Authors of the Four Pascal Books I read.
(If this sells they may want credit here.)
(3) My good friend who allowed me to use his
Mac II Ci system to test Calc for Soft AT
compatibility.
(4) Borland -- The company the wrote Turbo Pascal.
and last, but most certainly not least,
(5) MY FAMILY, they have put up with so much.

Calc 1st release in current format Sept. 6, 1991
Maintenance Releases:
--------------------
Version 2.01 -- program was modified
so that the top menu bar does not have two A
highlighted hot keys. One spelling error in
the program was corrected. Sept. 11, 1991
Version 2.02 -- Data entry & Result window
was moved down to get it out of the way of the
menu boxes. Oct. 3, 1991
Version 2.10 -- Ohms Law, Power Law, and Ohms Law/
Power Law definitions added. Menus reconfigured
for Mac/Borland like appearance. Registration code
added to allow registration via electronic fidonet
mail or US/International Mail. To you, the user,
this means that with each version of Calc 2.10
you will get the same exact screens you now see
except for the registration reminders. What you
see when you get Calc 2.10 is what you will get
in a Calc 2.10 registered version.
October 11, 1991
CALC version 2.15 which you now have:
Upgraded calc by adding screen clearing tied to
ESC key or mouse selected clear screen in menu
item CONTROLS. Added quit/exit to controls.
Changed screen to all black in the data area.
Disclaimer: I cannot be held responsible for the
use of this product. Calc contains no viruses
when it leaves my computer NOR WILL IT EVER
CONTAIN THEM! Please check all your software for
viruses. Protect your computer and time investment.
Thank you! ** Ken Otto **
