DC CIRCUIT ANALYSIS
Version 1.2, June 1993
Copyright 1991, Arthur Tanzella
All Rights Reserved
The DC Circuit Analysis program contains over 100 files occupying
approximately 800 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 300 Kb and 350 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 the 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".
