C64 mode provides the BASIC 2.0 language, 40-column output and
access to 64K of RAM. The main keyboard layout, except for the
placement of the function keys, is the same as that of a Commodore
64 computer. All the C64 graphics, color and sound capabilities are
retained, used exactly as on a Commodore 64.
CP/M Mode
In CP/M mode, an onboard Z80 microprocessor gives you access to
the capabilities of Digital Research's CP/M Version 3.0, plus a num
ber of new capabilities added by Commodore. The Commodore
128's CP/M 3.0 package (also known as CP/M Plus) provides 128K of
RAM, 40- and 80-column output, access to the full keyboard, includ
ing the numeric keypad and special keys, and access to the stan
dard peripherals. With some exceptions, you will be able to choose
from thousands of popular software programs—already available,
and already proven. (Programs created for a specific computer may
not run on the Commodore 128. Also, CP/M 3.0 programs on the
Commodore 128 may run somewhat slower than CP/M systems on
high-priced machines.)
Chapters II, III and IV, which include Sections 3 through 15, tell you
how to access and use the capabilities of the three powerful and
versatile operating modes of the Commodore 128 Personal
Computer.
Before you turn on your Commodore 128, there are a few things to
check to make sure that you get started properly. One thing you
should do before powering up the computer is to make sure the
40/80 key on the top row of the keyboard is set to match your monitor.
For example, if you have a 40-column monitor, the 40/80 key should
be in the up position. If you have an 80-column monitor the 40/80
key should be depressed.
