DC CIRCUIT ANALYSIS
Version 1.1, March 1992
Copyright 1991, Arthur Tanzella
All Rights Reserved
The DC Circuit Analysis program contains over 100 files occupying
approximately 750 Kb of disk space, and is compressed into a single self-
extracting file called "DCINSTAL.EXE." This file was created using the LHarc
version 2.11 program, which is a copyright reserved freeware program written
by Haruyasu Yoshizaki.
To run the program, requires an EGA or VGA graphics adapter with 256 Kb of
RAM installed, and a color monitor. It also requires between 275 Kb and
325 Kb of available RAM after DOS, drivers and Terminate and Stay Resident
(TSR) programs are loaded. The actual amount of RAM required depends on the
complexity of the circuit, and whether on not EMS memory is available.
To install the program you must specify the drive and sub-directory on the
command line as follows:
DCINSTAL C:\DC
You can install to any drive or sub-directory specified on the DCINSTAL
command line, except a 360 Kb diskette.
To use the program I recommend you first print all the documentation files.
The DC.DOC documentation file includes a tutorial on semiconductors, logic,
and digital computer circuits. The documentation uses the IBM extended
character set. If you have an HP LaserJet (II, IIP, III, or IIIP) printer,
you should either set the default symbol set to "PC8," or copy the following
file to the printer before printing the documentation files:
COPY /B LASERJET.BIN PRN
This file can be found in the same directory as the document files. To print
all three documentation files, I suggest using the following command:
COPY *.DOC PRN
To start the program, change the default directory to the directory
containing the DC.EXE program, and type "DC" as follows:
CD \DC
DC
You can now choose a sample circuit and analyze it. To exit a screen use the
"ESC" key. At the opening menu choose "Exit without Saving."
