ALTAIR 68

of the micro-world

Measuring just 11” wide x 11” deep x 5” high, and weighing a
mere 7 pounds, the Altair ™ 680b is a complete, general-purpose
computer.

The secret to this revolutionary, smalf computer is its CPU
board. This double-sided board fits along the bottom of the Altair
case and plugs directly into the front panel board. It contains
the new 6800 microprocessor, 1,024 bytes of RAM memory, a 256
byte PROM monitor, provisions for 768 bytes of additional PROM
or ROM, and a single Interface port with a Motorola ACIA serial
interface adapter which can be configured either RS-232 or TTY.
A five level Baudot interface option is also available.

The Altair 680b can be programmed trom front panel switches,
or it can be interfaced to a video display terminal, or teletype-
writer. Three additional circuit boards can be plugged inside the
Altair 680b for further memory and interface expansion. The first
of these boards is a 16K static RAM memory board.

Software already developed includes Altair 680 BASIC with
all the features of the 8K BASIC previously developed for the
Altair 8800. These include Boolean operators, the ability to read
or write a byte from any I/O port or memory location, multiple
statements per line, and the ability to interrupt program execution
and then continue after the examination of variable values. This
software takes only 6.8K bytes of memory space and a copy is
included free with the purchase of the Altair 680 16K memory
board.

Other software includes a resident two pass assembler. The
Altair 680b is also compatible with Motorola 6800 software.

The Altair 6806 is ideal for hobbyists who want a powerful
computer system at an economic price. Altair 680b owners qualify

Apple Introduces the First Low Cost Microcomputer System with a
Video Terminal and 8K Bytes of RAM on a Single PC Card.

The Apple Computer. A truly com-
plete microcomputer system on a
single PC board. Based on the MOS
Technology 6502 microprocessor, the
Apple also has a built-in video termi-
nal and sockets for 8K bytes of on-
board RAM memory. With the addi-
tion 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 assem-
bled, tested & burned-in and has a
complete power supply on-board, ini-
tial set-up is essentially ‘‘hassle free”
and you can be running within min-
utes. At $666.66 (including 4K
bytes RAM!) it opens many new
possibilities for users and systems
manufacturers.

You Don’t Need
an Expensive Teletype.

Using the built-in video terminal
and keyboard interface, you avoid all
the expense, noise and maintenance
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
inexpensive RF modulator) and dis-
plays 960 easy to read characters in 24
rows of 40 characters per line with au-
tomatic scrolling. The video display
section contains its own 1K bytes of
memory, so all the RAM memory is
available for user programs. And the

MICROPROCESSOR

Keyboard Interface lets you use al-
most any ASCII-encoded keyboard.
The Apple Computer makes it pos-
sible 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 display vast
amounts of information simulta-
neously. The Apple video terminal

can display the contents of 192 mem-

ory locations at once on the screen.
And the firmware in PROMS enables
you to enter, display and debug pro-
grams (all in hex) from the keyboard,
rendering a front panel unnecessary.
The firmware also allows your pro-
grams to print characters on the dis-
play, 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 and BASIC).

8K Bytes RAM in 16 Chips!

The Apple Computer uses the new
16-pin 4K dynamic memory chips.
They are faster and take 4 the space
and power of even the low power
2102’s (the memory chip that every-
one 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 car-
ries both the address and data busses,
power supplies and all timing signals.
All dynamic 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 availa-

ble. That’s 32K bytes on-board RAM
in 16 IC’s—the equivalent of 256
2102's!

A Little Cassette Board
That Works!

Unlike many other cassette boards
on the marketplace, ours works every
time. It plugs directly into the upright
connector on the main board and
stands only 2” tall. And since it is
very fast (1500 bits per second), you
can read or write 4K bytes in about
20 seconds. All timing is done in
software, which results in crystal-
controlled accuracy and uniformity
from unit to unit.

Unlike some other cassette inter-
faces which require an expensive tape
recorder, the Apple Cassette Inter-
face works reliably with almost any
audio-grade cassette recorder.

Software:

A tape of APPLE BASIC is includ-
ed free with the Cassette Interface.
Apple Basic features immediate error
messages and fast execution, and lets
you program in a higher level lan-
guage immediately and without
added cost. Also available now are a
dis-assembler and many games, with
many software packages, (including a
macro assembler) in the works. And
since our philosophy is to provide
software for our machines free or at
minimal cost, you won’t be continu-
ally paying for access to this growing
software library.

The Apple Computer is in stock at
almost all major computer stores. (If
your local computer store doesn’t
carry our products, encourage them
or write us direct). Dealer inquiries
invited.

Simultaneous batch and timesharing;
BASIC, COBOL, FORTRAN IV and

assembly language in one computer

system.

$29,090 delivered.

Yes, the price is printed correctly even though
a computer system with these capabilities might be
expected to cost ten times as much.

The surprising power of this computer system
comes from a remarkable new software operating
system called ETOS (EDUCOMP’s Timesharing
Operating System) developed by EduComp Corpo-
ration. Using this system, a batch stream may be
running from a card reader with output going to a
line printer while simultaneously scuresof other
users may be running timesharing jobs from their
individual terminals in BASIC, FORTRAN IV,
COBOL, or Assembly Language. Or they may be
using the system’s powerful editor to create and
modify data files. And, through the unique virtual
memory technique employed by ETOS, each user
has access to 32K words of memory.

While ETOS is sophisticated and powerful , it
is also reliable and easy to use. Reliability is
assured because ETOS is built around Digital
Equipment Corp.’s dependable PDP-8/E computer
and peripherals. Its ease of operation means that
the system can run all day virtually unattended.

At EduComp, we know educational computer
systems. They’re our only business. You're wel-
come to call on and talk to any one or all of our
100 plus satisfied customers.

In addition to ETOS, we have single-user

HALF THE PRICE

The new Practicalc Spreadsheet for
Apple Computers

At twice the speed of Visicalc, and
with a host of additional features
unmatched by other programs, Practi-
Calc II just has'to be the best spread-
sheet for your Apple.

Not only does it have all the features
you'd expect of a first class spreadsheet,
it also acts as a database. It will
automatically arrange information
numerically or alphabetically and
allows you to search for and retrieve
information in seconds.

PractiCalc II also has an extensive
word processing capability, enabling

PRACTICAL COMPUTING June 1984

you to create and justify text for letters
or documents. In many cases, this
eliminates the need for a dedicated
word processor.

Add to this the higher speed at which
it copes with all the usual mathematical
and trig functions of the spreadsheet,
(add, subtract, multiply, divide, square,
root, logs and exponential), ata price far
below that of any vaguely comparable
program.

You’ll soon see that PractiCalc II
is destined to be the apple of every
owner’s eye. Pick one up for £69.95 at
any Apple dealer or phone PractiCorp
