A LOOK AT
THE IPC NEAT/40E
COMPUTER
In this article we set out to review the CMS
Music Card mentioned in a previous issue,
ramble all over the current computer scene
and end up reviewing the IPC NEAT computer
which uses the new AT standard chipset.
By ROSS MORTON
Regular SILICON CHIP readers
may recall seeing a "CMS Music
Card" mentioned in our Product
Showcase section last December.
At that stage, all we were able to
present was a brief description and
photograph.
Shortly after the issue went to
press, we were approached by
CompuHelp Australia, the local
agents for the card, to see if we'd
like to have one to play with for a
while. Before we could answer,
they asked "Would you like it inside
a computer - then you could have
a look at both ... "
Talk about making every post a
winner! Anyway, CompuHelp Aust-
ralia duly delivered an IPC NEAT/
40E computer system to our office,
with the CMS Music Card installed
in one of the spare slots.
The original specification of the
IBM "AT" machine (which, believe
it or not, is now over 4 years old)
had an 80286 processor running at
6MHz with 512K of RAM (although
expandable to 3MB). Since then
many refinements have been made
- not the least being speed (even
basic ATs now run at 8MHz) and
memory (up to 640K).
The IPC NEAT goes beyond this:
a clock speed of 16MHz means most
applications run appreciably faster
and it is possible to use a lot more
memory, above the DOS limit of
640K. (A group of the major software suppliers have come up with a
specification for extended memory
known as LIMs - Lotus/Intel/
Microsoft specification).
Not that the IPC NEAT is alone in
using this specification; most "top
end" computer manufacturers now
offer this option.
What's NEAT?
IPC COMPUTERS COVER THE range from a large 80386 tower system down to
PC XT compatible machines in quite small cases. All machines may be had
with hard disc drives and 3½inch or 5¼-inch floppies.

SILICON CHIP
Whoa! What's this "NEAT"
we're talking about? What happened to "AT".
Many readers would be aware
that the AT machine is now very
much "middle of the road" in computer performance. The newer
machines based on the 80386 processor literally run rings around
the older ATs or 80286 based
machines.
Despite the very high cost of
machines based on the 80386, many
customers are bypassing the AT to
have "the best".
This worried one 80286 manufacturer so much they decided to do
continue up-grading and releasing
DOS in parallel to OS/2.
For these reasons, the majority of
manufacturers, including IPC, have
remained faithful to th8 DOS
standard.
Incidentally, what about that
name "IPC"? It stands for Intelligent Personal Computer and is
a product of Essex Electric, of
Singapore. For our money, the logo
is perilously close to that other
three letter computer manufacturer of international standing. Golly, could that be an accident?
Graphics standards
The graphics capabilities of PCs
have come a long way since the
original days. While most computers still have the option of a
mono display to retain compatibility
with earlier software packages,
CGA (Colour Graphics Adaptor)
displays have given way to higher
quality EGA (Enhanced Graphics
Adaptor) and even better VGA
(Video Graphics Array) displays.
Emerging now are better yet
"PGA" or Professional Graphics
Adaptor standards, although these
are found only on very few high
level machines and require expensive monitors.
By far the most popular is the
EGA standard and this is the card
and matching monitor used on the
computer under review.
THE NEAT/40E MACHINE under review: it uses the new enhanced AT chipset
which allows performance almost to the 80386 standard to be achieved. In the
turbo (zero wait state) mode it runs at 20.5MHz.
something about it. The giant US
"Chips & Technologies" corporation reasoned, quite logically, that
if they could up the performance of
the 80286 chip set to approach
80386 standard but hold the cost
down, customers wouldn't be so
quick to pay the extra bucks for not
much more byte.
Which is how the NEAT Chipset
(or New Enhanced AT) came into
being. The performance does approach the speed of the 386: 16MHz
vs. the 386's normal 20MHz. It also
allows addressing of up to 8MB of
memory (RAM), along with a few
other refinements such as the LIM
4.0 support already mentioned.
Unless you 've been in Outer
Mongolia for the last couple of
years, you would be aware of IBM's
much touted "micro channel" architecture and OS/2 operating
system. Despite the huge amounts
of money pushing this system, by
and large most manufacturers have
stuck with the DOS system.
Even if OS/2 support increases
much more rapidly than at the moment, industry analysts expect DOS
to be the dominant system for many
years to come - simply because of
its mammoth installed base and the
huge variety of software available.
In fact, a recent survey of US corporations revealed over 80% had
no plans to switch to OS/2 (Computerworld, February 10th issue).
And the inventor/supplier of
DOS, Microsoft, has promised to
Appearance
The IPC computer is supplied in
two boxes, one holding the EGA
monitor and one holding the computer, keyboard and accessories.
The keyboard is individually boxed
inside the main system box and
comes with a clear hard plastic
keyboard cover. This not only protects the keyboard in transit but
can also be used as a keyboard
cover when the machine is not in
use.
Removal of the keyboard reveals
the computer itself, securely contained within a foam transportation
enclosure. Also in the box are the
operation manual and setup disc,
DOS manual with DOS & GW
BASIC discs, and a power cable.
The computer supplied for this
review was equipped with a
5¼-inch 1.2MB floppy disc and a

40MB hard disc. There is also provision in the machine (and on the
front panel) for an additional
5 ¼-inch drive and a 3 ½-inch drive.
drive.
As is typical of "AT" style
machines these days, a key switch
is provided to prevent system use
by locking the keyboard. We're not
quite sure why this feature is included: we've yet to meet anyone
who actually uses the keyswitch or,
more to the point, even knows
where their keys are!
Still, it could be a handy security
device to prevent prying eyes or
0ther unauthorised access.
Alongside is a system reset
switch and a "turbo" switch: press
the first and the machine warm
boots, press the second and the little man inside pushes down on the
accelerator.
Two LEDs on the front panel
show power on and when the internal hard disc drive is in operation.
In addition, a two digit numeric
display shows the speed of operation - 8 for standard 8MHz, or 12
for '"turbo".
On the rear of the machine are 8
slot dust covers, of which four are
taken up with standard "D" connectors for the parallel printer port
and two serial (RS-232C) ports,
along with the monitor (video)
socket. The 5-pin DIN socket for the
keyboard is on the main body of the
computer.
Of particular interest to us was
an additional set of connectors: one
3.5mm and two RCA, along with an
edge-mounted knob looking suspiciously like a volume control. This
was for the CMS Music Card (the
original reason for the review
machine)! But more on that anon.
The view inside
Removing the top of the computer
was simple: just a couple of screws
to undo and it lifts off. Inside, the
case was a joy to behold, considering some of the messes we'vP. seen
THIS IS THE STANDARD IPC AT machine which runs at 8 or 12MHz.
All machines are available with 84 or 101 keyboards.

in the past. The case is heavily
plated inside to prevent corrosion
(some low cost computers are either
bare or have a coating of spray
paint - one scratch and corrosion
sets in).
The layout of components within
the case reflected the same care
and attention - wiring all neatly
dressed and tied, all major components socketed for easy service
(should it ever be required), and so
on.
Previously mentioned is the provision for extra drives: in fact, with
the top off, you can see room for a
total of three 5 ¼-inch and two
3 ½-inch devices - so there's plenty of room for more hard disc
drives, tape streamers, etc.
Without the CMS Music Card,
there are still three full length slots
and one half length slot available leaving plenty of room for system
expansion.
Performance
Sorting out the level of performance of a computer almost requires the wisdom of Job. What
we're trying to say is don't believe
all the figures you might read especially without qualification!
And with proprietary software
often looking for specific performance to be able to operate properly, there aren't all that many things
that can be changed away from the
"standard" before the software
won't work.
Fortunately, there are a couple of
"yardsticks" which have evolved to
help compare computers.
The first of these is the "Landmark" speed test: a set of instructions is run in the computer and the
resulting speed is displayed in
graph form on the monitor screen.
It shows the speed relative to the
original IBM AT specification.
On "normal" speed, the IPC
NEAT/40E had a Landmark of 10.0
- very respectable. On "turbo"
speed (operating with zero wait
states), this increased to a whopping 20.5 .
The second yardstick is the Norton "SI" - or system information.
As well as showing the configuration of the machine (processor,
memory, etc), it shows the speed of
operation. The Norton SI on the test
machine was a very respectable 18.
This compares well with the normal
"AT" SI of around 12/13 (depending on the machine).
What this all means is that the
machine is fast - very fast. Many
applications could be run even
fpster with the addition of the optional 80287-10 maths co-processor. But for most users not involved
in, say, large spreadsheet calculations, the additional expense of the
80287 (about $500 or so) is hard to
justify.
We mentioned compatibility:
again, this is a thorny issue.
Everyone claims compatibility after all, the machines are all IBM
"clones" , aren't they?
Things mightn't
be all they seem!
Years ago, Microsoft's "Flight
Simulator" became the compatibility test. If it ran Flight Simulator, it
was "compatible" . Then designers
made sure that, if nothing else,
their machines ran Flight Simulator. Some readers may remember
the bad old days when one
wandered around a PC show and
all the PCs were running Flight
Simulator. Ask them to run
anything else and they could be in
trouble.
Nowadays, most reviewers run
whatever software they ha ve
available - including, hopefully, a
couple which they know are " iffy" .
We tried about thirty different
software packages with no problems whatsoever: everything from
some very advanced games right
through the spectrum of business
and professional programs.
Despite not being a "386"
machine, it made short work of the
power desktop publishing packages
such as Ventura 2.0 and Pagemaker
3.0.
The IPC NEAT/40E handled
everything we could give it - with
ease and speed. On " turbo", it
flew!
Documentation & software
Included with the computer are
DOS 3.3 (not the latest version, but
nevertheless recent - and the one
most favoured by PC manufacturers), GW BASIC, full manuals
for both, and an IPC proprietary
"setup" disc, along with its manual.
A nice touch included on the IPC
machine was a little batch program
which comes up when you first turn
the machine on. It lists the configuration of the computer (ie, the
options that were fitted), and
details of the 30-day money back
guarantee and the 12-month warranty.
It then loaded an intriguing utility
program called "Directree" . It's
one we hadn't heard of before but
according to CompuHelp Australia
(who are also the Australian agents
for the US program), it allows you to
manage your computer system
much more efficiently and easily
than just using DOS.
Apparently it's similar in many
respects to "XTREE" but (again according to CompuHelp Australia)
does much more, and at a lower
cost.
DirecTree is not normally included on the machines but is available
as an option for around $80. It' s
well worth the extra.
Conclusion
Compatibles are, to use a cliche,
a dime a dozen. Normally, you get
what you pay for - buy low, you
get low.
The IPC range tends to put the lie
to that statement. Th e IPC
NEAT/40E is very competitively
priced: the machine as reviewed
sells for just under $4500 - and
that includes the monitor and
keyboard, sales tax and an on-site
12-month warranty service agreement.
Its performance is up there with
the best of them and would suit the
power user, particularly in small
business. Now, where's the cheque
book?

Footnote : This started as a
review of the Creative Music
System card, which was fitted to
the IPC AT/40E. However, the
computer itself has taken far
more space than originally intended, so the CMS card will have to
wait for a later issue .
PCBreeze II
PCB reeze is a sophisticated tool for designing Printed Circuit Boards. It allows a board
to be created, viewed and modified on an
IBM compatible computer.
PCBreeze has been designed with ease of
use in mind. Most commands are at most
two keystrokes away, with additional information asked for explicitly. A pop up men u
sys tem is avai lable. The menus make
PCBreeze easy to learn and use but does not
hinder the experienced user.
The system uses a 50 mil ( 1.27 mm) grid.
This resolution is more than enough for
most tasks. It has two layers for the artwork
as well as text and component overlay.
With board area sizes of up to 400 square
inches there is plenty of room to work.
There is a variety of common pad and line
sizes to choose from. Also standard is a DIP
and SIP command to put down these pad
patterns. User defined pad patterns may be
saved and used as libraries later.
Incl uded in PCBreeze is an Autoro uter'.

points marked out by the user or accept a
netlist.
