Computer. A truly complete microcomputer system
on a single PC board. Based on the MOS Technology
6502 micro- processor, the Apple also has a
built-in video terminal and sockets for 8K bytes
of onboard RAM memory. With the addition of
a keyboard and video monitor, you'll have an
extremely powerful computer system that can
be used for anything from developing programs
to playing games or running BASIC.
Combining the computer, video
terminal and dynamic memory on a single board
has resulted in a large reduction in chip count,
which means more reliability and lowered cost.
Since the Apple comes fully assembled, tested
& burned-in and has a complete power supply
on-board, initial set-up is essentially "hassle-free"
and you can be running within minutes. At $666.66
(including 4K bytes RAM!) it opens many new
possibilities for users and systems manufacturers.
You Don't Need an Expensive
Using the built-in video terminal and keyboard
avoid all the expense, noise
and mantenance associated with a teletype. And
the Apple video terminal is six times faster
than a teletype, which means more throughput
and less waiting. The Apple connects directly
to a video monitor (or home TV with an in- expensive
RF modulator) and dis- plays 960 easy to read
characters in 24 rows of 40 characters per line
with automatic scrolling. The video display
section contains its own 1K bytes of memory,
so all the RAM memory is available for user
programs. And the Keyboard Interface lets you
use almost any ASCII-encoded keyboard.
The Apple Computer makes it
possible for many people with limited budgets
to step up to a video terminal as an I/O device
for their computer.
No More Switches,
No More Lights
Compared to switches and LED's,
a video terminal can dis- play vast amounts
of information simultaneously. The Apple video
terminal can display the contents of 192 memory
locations at once on the screen. And the fimrware
in PROMS enables you to enter,
display and debug programs (all
in hex) from the keyboard, ren- dering a front
panel unnecessary. The firmware also allows
your programs to print characters on the display,
and since you'll be looking at letters and numbers
instead of just LED's, the door is open to all
kinds of alphanumeric software (i.e., Games
8K Bytes RAM in 16 Chips!
The Apple Computer uses the new 16-pin 4K dynamic
memory chips. They are faster and take 1/4 the
space and power of even the low power 2102's
(the memory chip that everyone else uses). That
means 8K bytes in sixteen chips. It also means
no more 28 amp power supplies. The
system is fully expandable to 65K via an edge
connector which carries both the address and
data busses, power supplies and all timing signals.
All dy- namic memory refreshing for both on
and off-board memory is done automatically.
Also, the Apple Computer can be upgraded to
use the 16K chips when they become available.
That's 32K bytes on-board RAM in 16 IC's --the
equivalent of 256 2102's!
