Introduction
Your Apex TM by Epson® personal computer comes in two ver-
sions: the Apex Plus with two 360 KB (kilobyte) diskette drives,
and the Apex Plus 20 with one 360 KB diskette drive and one
20 MB (megabyte) hard disk drive.
Both versions have 512 KB of internal memory, called random
access memory or RAM. RAM determines the size of software
programs you can run and the data files you can create. With
512 KB of RAM, you can run most large programs and create
large data files.
Most software programs expect a computer to have two diskette
drives, one for the program diskette and one for a data diskette.
The Apex Plus provides two diskette drives so you do not have
to spend time switching diskettes. The Apex Plus 20 hard disk
drive and diskette drive provide the same convenience and let
you take advantage of the hard disk’s large storage capacity and
faster performance.
Depending on your needs, you can use either a TTL mono-
chrome monitor or an RGB (red-green-blue) color graphics
monitor with your computer. The Apex monochrome monitor
is a good choice if you are using word processing and spread-
sheet programs. The Apex color monitor is an excellent choice
if you use software designed for color graphics.
Your Apex comes with a multi-graphics adapter (MGA) card so
you can display color or monochrome graphics on your monitor.
The card is already installed in one of the five
option slots
in the
computer. The MGA card also includes a game port so you can
easily connect a joystick to your computer. You can replace the
MGA card to use another type of monitor, such as an enhanced
graphics adapter (EGA) monitor or a video graphics array
(VGA) monitor.
