Commodore 128D - Using Software

Using Software
See the booklet "Introducing the Commodore 128D Personal Com
puter" for instructions on how to set up the 128D with your monitor
or TV and peripherals.
Regardless of which screen format you are using, check to see that
the 40/80 key is in the desired position. If it's not, you may get no
picture at all because the monitor switch may be set for the opposite
screen. (See Section 5 for a description of all the special keys used
in C128 mode.)
If you are using a MAGIC VOICE speech module, insert the module in
the expansion port and, while holding down the Commodore key,
turn on the power switch. Never plug in any cartridge with the
power turned on.
If you experience difficulty getting a cartridge to power-up in C64
mode, plug in the cartridge with the power off; then hold down the
Commodore key and turn on the computer.
If you have the external CP/M 2.2 cartridge marketed for the Commo
dore 64, do not plug it into the Commodore 128. The Commodore 128
has a Z80 microprocessor already on-board for CP/M 3.0. If you do
plug in the CP/M 2.2 cartridge, it can cause unpredictable results.
If you are using software involving a light pen, plug the light pen into
Controller Port 1, located on the right side of the C128 near the power
switch.
If you have the 1764 RAM expansion module for the Commodore 64,
DO NOT use it with the Commodore 128. The 1700 (128K) or 1750
(512K) RAM expansion modules are designed for the C128 hardware.
