trouble w i t h the cover uprooting

He particularly had trouble w i t h
the color T V m o n i t o r and discussed that at great length . . .
including a severe problem he had
w i t h radio frequency hash f r o m
the computer. He stressed this a
couple o f times and then went on
to gripe that there were no peripherals available for the Apple bus.
He d i d n ' t like the game paddles
supplied, so a great deal o f the article was devoted to his making
his own joystick, an engineering
t r i u m p h o f which he seemed extraordinarily p r o u d . He left me
with the strong impression that
before I could do much w i t h the
Apple 1 w o u l d have t o duplicate
his chore o f buying all the parts
and building my own joystick. I
w o u l d then have to dig into the
Apple and wire my new control
Absent f r o m the review was
any objectivity or discussion o f

c o m p u t e r - p o r t r a i t o u t f i t s at
shows, shopping centers, fairs,
vacation spots, etc. It turns o u t ,
according t o a release f r o m Centronics (which we'll be publishing) that there are fortunes to be
made w i t h these systems.
One o f the exhibits at the San
Jose show was a portrait system
by M i c r o W o r k s , a new o u t f i t in
Del M a r ( C a l i f o r n i a , o f course).
Their price for a complete system
was ridiculously low . . . a r o u n d
a quarter that o f one o f the l o w est-priced commercial systems.
W h i l e the cost o f the equipment
needed to make $100,000 in sales
(mostly profits) over a six-week
period is not relevant i f it's under
$50,000 . . . not many locations
w i l l produce that a m o u n t o f
dollars . . . so a few bucks saved
is a few bucks earned.
Since many computer hobbyists are not totally opposed to
making money w i t h their systems, w e ' d like to have some articles on commercial applications
o f microcomputers . . . such as
for computer portraits.
First European Microcomputer
The European agents for Kilobaud have forwarded i n f o r m a -
t i o n on N A S C O M 1, a microcomputer kit selling for 980 D M
( f r o m an address in T r i e r , W .
Germany). The system uses a Z-80
chip and has its o w n bus structure, w h i c h the literature doesn't
d i v u l g e . They do have a
N A S C O M to S-100 bus interface
board available, so any o f the
hundreds o f S-100 boards can be
used w i t h the system. They also
have a Kansas City cassette interface available.
The kit includes a f u l l alphanumeric keyboard and character
generator. It requires a T V set for
video display a n d a separate
power supply (another 130 D M ) .
It appears t o have 4K o f memory
and includes a small operating
system ( N A S B U G ) in R O M and
its o w n cassette system, not com-

patible w i t h any other k n o w n
system (as usual).
M y plans are t o be in Europe in
M a y , and I hope to have a fuller
report on N A S C O M after the
M a y show in Paris. Trier is quite
near the L u x e m b o u r g border,
and is not that far f r o m Paris. It
is a beautiful o l d city, w i t h many
Roman ruins . . . such as the remains o f extensive o u t d o o r
baths, and a coliseum for Roman
games. I w o n ' t have a chance to
get up there to see the N A S C O M
d i s t r i b u t o r ; however, perhaps I
will have a chance t o visit the
factory in the U K on the way to
Paris.
T o get your best shot at not getting a bad deal, I suggest the following procedure. This has to do
w i t h firms about which you may
have a question . . . not steady
advertisers in Kilobaud
such as
S.D. Sales, G o d b o u t , etc. Before
you plunk a big bunch o f money
in an envelope, take some precautions.
1. Write a letter to the f i r m
asking for a c o n f i r m a t i o n o f
prices and a definite commitment
on delivery w i t h i n t w o weeks o f
your order. Keep a copy o f this
letter in your files.
2. If they do promise delivery
w i t h i n t w o weeks, it is time to
place your order, l f t h e y s a y n o . i t
is time to hold o f f until they get
their act in shape. I f you are going to order, send them a certified
check or money order for the
amount, or the order and a letter
explaining exactly what you are
ordering, giving every possible
detail. State clearly that shipment
is to be made w i t h i n t w o weeks or
else your check is to be returned.
Send this letter by certified mail,
with a return receipt. This costs a
dollar and may be worth it. I f you
are not extremely clear in your

There are several firms that are
not permitted to advertise in Kilobaud because we have had so
many complaints about them.
But, outside o f checking the ads
in Kilobaud, how can you protect
yourself against rip-offs? Not
that an ad in Kilobaud is positive

taken in too . . . and o f course
there are still some credible advertisers w h o are not running ads

Good News and Bad News
Perhaps you've noticed that
prices o n everything have been
inching up. As long as we are all
so enthusiastic about supporting
an ever-growing government, one
that has a strong vested interest in
spending, not saving, i n f l a t i o n is
going to be a fact o f life. Y o u ' v e
probably read about the recent
postal hike and you may know
about the next one that's coming.
1 sense t h a t s o m e t h i n g has
changed in postal rates for maga-
zines when I have to pay 72c a
copy to mail an issue o f Kilobaud
and remember when I paid 5®
each to mail 73 Magazine.
The excuses include more than
postage. Paper has doubled in
price in recent months, w i t h the
grades o f paper we used t o use being phased out and forcing us to
use what the paper mills are m a k ing . . . paper so t h i n it is getting
d i f f i c u l t t o t u r n a page w i t h o u t
skipping one or t w o and hardly
noticing i t . Printers, needing bigger Rolls Royces and yachts, have
upped their take . . . and so it
goes.
The b o t t o m line is an increase
in Kilobaud's
one-year subscription to $18. Since about half o f
our subscribers opt for a threeyear subscription for $36, and we
are not increasing this price, the
net to us w i l l be about 11 percent.
This will put us back where we
were when Kilobaud started.
W i t h a very high percentage o f
the renewals coming through for
three years, it w i l l be the newcomers to the magazine w h o will foot
the i n f l a t i o n on the one-year rate.

Article Submission
Hey, i f y o u ' r e going t o write an
article don 7 send it to more than
one magazine at a time, O K ?
That isn't the way the game is
played. I d o n ' t think any o f us
likes t o be put in a position o f
" b i d d i n g " on a piece o f material
(and I w o n ' t ) , but even worse
than that are the possible messes
that can occur.
M y most recent experience involving dual submissions resulted
Book Manuscripts Wanted
The Kilobaud
book department has been expanded recently
and several books are in the
works; more are needed . . . i f
you are looking for fame and fortune.
A publisher has t w o major
f u n c t i o n s , a n d Kilobaud
is
uniquely suited to both o f these.
First comes the printing o f the
book, which can be an expensive
proposition. In our case, we edit
the manuscript, do the drafting
o f any schematics, set the type,
do needed photography, p r o o f read the type, lay out the pages,
put the type, photos and draftings together on the page, shoot
the negatives, make the printing
plates, buy the paper, print the
book, bind it and ship it. Everything is done right at
Kilobaud!
Few publishers have such a complete setup . . . or one nearly as
efficient.
The second function is advertising and distributing the b o o k .
Again we have everything, including a magazine to help with
the advertising. Our marketing
staff prepares promotions for
c o m p u t e r stores, b o o k s t o r e s ,
radio stores, etc. Our sales staff is
in touch w i t h all possible book
outlets. W i t h over a dozen books
now being distributed, we know
the market well.
What kind o f books are needed? Microcomputer-fundamental
books are still selling well, despite
the large number o f them out
there. Books o f programs for

system or you can take advantage
o f the numerous peripheral devices (more appear every m o n t h )
that can talk to the IEEE-488 bus.
The PET-488 cable assembly
plugs directly i n t o the edge connector o n the back o f the P E T
computer and has a completely
488 compatible connector on the
other end. The cable itself meets
all IEEE-488 specifications f o r
impression o f t w o guys t a l k i n g to
each other. The result is a very
readable pair o f books that are
also extremely i n f o r m a t i v e .
The books aren't flawless, o f
course. The most i r r i t a t i n g things
are the typographical errors. Fortunately, only a couple o f them
are likely t o cause you any confusion while reading. A n errata
sheet w i l l be available soon.
Sorry, but even t h o u g h I tried, I
c o u l d n ' t come up w i t h anything
else bad t o say.
I n short, these books are ideal
for someone w h o is just getting
into home c o m p u t i n g . Even for
the more experienced reader, they
tie up a lot o f the loose ends and
show the relationships among
things that may not have been
clear before.

From the originator of the Digital Voltmeter. Non-Linear Systems comes the MS-215 Miniscope. It is a fine
electronic instrument wittra great deal of measuring capability and excellent accuracy. Its design is modern, utilizing
the latest in low-powered integrated circuits, and it is packaged into the smallest practical size. The instrument fits into
many briefcases and tool boxes with room to spare.
Operating characteristics have been chosen so that the MS-215 will make all of the measurements needed in
servicing most electronic equipment. It is field-portable so its use is not restricted to the bench.

TYPESETTING MONITOR
We have acquired an unusual video monitor. It was originally designed for
and used in the photo typesetting industry. As the typesetter composed his
copy, the copy would appear on the screen. The tube is a flat type about
6 W x 2V»", since only one line o f copy was scanned at a time. Most o f the
tubes have slight burn marks, but are still usable. We have all the circuitry,
and w i l l supply the circuitry w i t h each order. We believe most o f these units
are in working order, since they were taken out o f service when the
equipment was upgraded. Looks like a good start to make into your own
video monitor at giveaway prices. We have them w i t h and w i t h o u t the CR
tubes. Sold as is only.

TV HOCKEY and SOCCER GAME
plus VIDEOCUBE
For some time we have been selling our V I D E O CUBE, the T V interface between computers, cameras, etc., and your T V set. We sold them in k i t
f o r m , and to date we have sold over 3,000. We sold
the complete V I D E O C U B E , when available, for
$16.95.
We now have a limited number of Hockey-Soccer Video games, complete w i t h V I D E O C U B E interface,
at a new low price of $18.95; previously sold for $27.50 in k i t form. This gives y o u two games, at two
levels o f skill, w i t h L E D readouts for scorekeeping. This game sold in Boston department stores for
$79.50.

ICs
Since last summer, we have been selling 2 wire wrap boards,
Our Stock No. 6 5 5 8 K w i t h approximately 100 sockets, and
our Stock No. 6 5 5 9 K w i t h approximately 45 sockets.
These have been successful, based o n your orders and
reorders. We now have the same boards, b u t w i t h the
sockets still containing the original SN7400 series ICs that
1
were used in the computer that these boards were designed
f o r . We checked the value of these ICs, against the lowest
price ICs in several Electronics magazine, and f o u n d that
at the lowest possible surplus prices, the values o f the ICs on the 100 socket board ran to over $40.00. A sample of
some of the chips on the board we looked at are as f o l l o w s : 74H87, 7486, 74107, 7451, 7400, 7404, 7495, 7493,
7492, 74193, 7489 and many others, to numerous to mention. Also on some boards, are a few linears, and phase
locked loops. N o t everyone needs every chip, but if y o u are w o r k i n g at all w i t h T T L , this is a great o p p o r t u n i t y to get
an inventory of the most useful chips at a ridiculous price. We are selling the 100 socket board w i t h about 100 chips,
for $10.00 more than the board itself, and the 45 socket chip for $5.00 more than the board itself. We w i l l also include
w i t h each board, 2 edge connectors w i t h the 100 socket board, and 1 edge connector w i t h the 45 socket board.

a new microcomputer system

Does that give it away?
Watch out for the dealer network

MST MOUTH'S
MYSTERY R€dD€R
Last month's " W h o ' s Behind the Kilobaud" was Steven
Pereira, president of the Microcomputer Store in Nashua.
Nashua now has three-going-on-four computer stores,
which is remarkable considering its size. New Hampshire's freedom from a sales tax, which saves substantial
dollars on a computer system, is drawing many companies to Nashua. Among the many new factories put in
recently were a couple by DEC.

• P R O G R A M M I N G I N PASCAL by Peter
Grogono. The computer programming language PASCAL was the first language to
embody in a coherent way the concepts of
structured programming which had been
defined by Edsger Dijkstra and C.A.R. Hoare.
As such it is a landmark in the development
of programming languages. PASCAL was
developed by Niklaus Wirth in Zurich; it is
derived from the language A L G O L 6 0 but is
more powerful and easier to use. PASCAL is
now widely accepted as a useful language that
can be efficiently implemented, and as an
excellent teaching tool. This book is intended
for people who want to write programs in
PASCAL. It does not assume knowledge of
any other programming language and it is
therefore suitable for an introductory course.

we're looking for
someone serious about
personal computing!
8-bit? 16-bit? The better of
the two? The question is elemental - hardly worth consideration. What matters is
your "machine's" CPU, its
"architecture," and most importantly its instruction set.
That's where the power is
and that's exactly why we're
telling you about the KD11-F.
The KD11-F is the CPU we
chose for the Heath Hll. It's
built by DEC, is the same
CPU that's the cornerstone
of the popular LSI-11 family,
and is the main reason our
16-bit is the most powerful
16-bit in its price class! Bells
and whistles? Hardly!
Fact: The KD11-F has eight
registers. Six of which are
general-purpose and nondedicated! That alone means
virtually unlimited programmer flexibility!
Fact: Most computers in
the 16-bit class use three
types of instructions (memory reference, operate or accumulator control, and I/O
instructions). The KD11-F accomplishes all data manipulations with a single set of
instructions - which results
in very efficient operation!
Fact: The KDll-F's PDP-11
instruction set has the most
I
Schlumberger
powerful repertoire of instructions of any computer
in its price class.
What it all boils down to
is that the Heathkit H l l
gives you fantastic flexibility, unparalleled high-speed
program execution, a n d
unmatched performance!
Our Hll CPU isn't for everyone. It's for someone serious
about computing
someone like you!

The Hll uses Digital Equipment Corporations 16-bit LSI-11 CPU. Exactly the
same CPU found in the famous DEC
PDP-11 — probably the most popular
commercial and industrial computer in
the world. So now a low-cost kit gives
you the speed, power and throughput
of the world's most popular professional

Software and support. As an Hll
owner, you have access to an incredible
range of software — editor, relocatable
assembler, linker, absolute loader, debug
program, I/O executive program, dump
routines, BASIC and FOCAL. And, by
joining the DEC user's group (DECUS),
you can have access to one of the largest
software libraries in the world. And
there's more to come. Much more.
Of course, the H l l executes the powerful PDP 11/40 instruction set which includes over 400 commands. And the fully
assembled KD-11F CPU board includes
4K x 16 bits of memory. The backplane
accepts up to six additional modules
