In an industry as dynamic as the personal computer industry, it's inevitable that computers
will be built with more and more memory.
It's equally inevitable that newer, faster, more
powerful software will be written to take advantage of that extra memory. Where does that
leave you?
It leaves you in great shape, because the Apple IIe is designed to grow as technology grows.
You can add memory to your Apple IIe right now by adding an extended 80-column card.
Adding a Co-processor
A co-processor is a microprocessor that works with or overrides the microprocessor that comes
with your machine.
The main reason you'd get one is to take advantage of software developed
for other computers software that wouldn't otherwise work on your Apple IIe.
The most popular co-processor for the Apple IIe is the Z80 processor, which lets you run
programs based on the CP/M® operating system.
By plugging a Z80 card into your Apple IIe, you can select from over 20,000 CP/M-based
programs, many of them free (public domain) programs.
Ask your dealer for information on other co-processors that let you take advantage of
MS-DOS-based programs, and co-processor cards that increase the speed or enhance the graphics
of Apple IIe programs.
Other Peripherals
One of the secrets of the Apple II's success is its open architecture. There's hardly any limit
to the number and variety of gadgets that you can attach to the Apple IIe to make it a more
powerful, productive, or playful machine.
Here's a small sample of the more exotic peripherals that you could add to your computer
system:
Clock Card: Makes it possible for programs, for example, to record the date and time a given
file was last revised. With a clock card and home control devices, you can program your Apple
IIe to turn lights and kitchen appliances on and off. With a clock card and communications
software, you can communicate with an information service at times you specify to take
advantage of cheaper telephone rates.
Accelerator Card: Makes most programs run almost four times faster than normal. It's
especially useful for spreadsheet and other number-crunching applications.
Print Buffer Card: Lets your Apple IIe send an entire file to your printer at one time so you
can use your computer for other things while the file is being printed. The buffer card plugs
into your printer interface card.
Voice Input Device: Lets you communicate with certain programs by using verbal commands rather
than typed commands. Like the mouse, it's an intuitive way to communicate with computer
programs.
Synthesizer: A peripheral device that can simulate a variety of musical instruments ranging
from woodwinds to percussion. Using special software, you can compose and orchestrate your own
music.
Home Control Devices: Peripheral devices that can work with your Apple IIe to control the
temperature of your home; turn your lamps, sprinklers, coffee maker, and other appliances on
and off; and monitor your smoke and burgler alarms.
