THE MEGA ST(e)
**************
THE TT FOR THE REST OF US ?
**************************
by John Hutchinson
When Atari's flagship computer, the TT/030, was unveiled, there were
untold "oohs" and "aahs" heard from Atari fans around the world. Long
had we waited for the next generation of powerful Atari computers.
The 32 mhz 68030-powered TT was indeed a screamer and its enhanced graphic
modes and plethora of industry standard ports enticed us to believe the
long wait was well served. But when we saw (gulp) the TT's price tag, we
wondered what had happened to the once proud slogan of "Power Without
The Price". Sure the TT is a bargain compared to many other graphic
workstations, but the minimum entry cost is a quantum leap from what
dedicated Atari users were used to paying for ST's. What was needed
was another machine to fill the niche between the low end 1040ST(e)/Mega ST
line and the ultra powerful (and expensive) TT.
Well, take heart friends, for the powers that be in the hallowed halls
at Atari have released a new machine which may well come to be considered
the finest they have yet assembled -- the MEGA ST(e) ! ! !
What makes this new machine such a potential winner? Let's start by
checking out few of it's standard features:
* 16MHz 68000 w/cache
* 1,2 or 4 Megabytes of RAM
* Built in 50Mb hard drive (in the 2 and 4Mb versions)
* Easy to upgrade SIMM memory modules
* TOS 2.5
* Extensible control panel
* ST(e) 4,096 colour palette
* ST(e) PCM stereo sound output
* VME expansion port
* LAN network port
* Blitter graphics chip
* TT style case and detachable keyboard
THE WEDDING CAKE REVISITED
The Mega ST(e) is, in a word, BIG. Identical in style to the TT, the
unitized case holds computer internals, floppy and hard disk drives, and
measures a whopping 19x11x4 inches PLUS the detachable keyboard. If you
add a cartridge such as the Spectre GCR, the machine seems to take on
immense proportions, if your work area is on the smallish side. The so-
called "wedding cake" style TT case has been the subject of much debate;
you either like it or you do not. Fortunately, Atari chose to mold the
Mega ST(e)'s case in a platinum grey colour which many find more
appealing than the rather anemic off-white colour of the TT.
The "feel" and tactile response of the detachable keyboard is superb.
Function keys are now shaped more sensibly so you don't need parallelogram
shaped fingers anymore. Both mouse and joysticks conveniently plug into
the sides of the keyboard. Some of the TT's design flaws haunt the
MegaST(e); for example, the coiled keyboard cable plugs into the RIGHT
hand side of the keyboard and into the LEFT hand side of the computer,
effectively cutting the usable length of the cable in half. A more
serious flaw is the proximity of the keyboard cable jack to the cartridge
port. With the cable plugged in, a large cartridge (such as the Spectre
GCR) may not be fully inserted. It still works, mind you, but does not
leave the user with much peace of mind. Inserting or removing a cartridge
while the computer is powered up is potentially hazardous to cartridge,
computer, and wallet.
Next to the cartridge port on the left side of the computer, we find
the traditional MIDI IN and MIDI OUT ports, power reset switch and a LAN
(Local Area Network) port. The latter is a welcome addition which will
ostensibly allow easy connection and communications between multiple
computers and other devices via an AppleTalk like network. Software
supporting the LAN protocol is sure to come so stay tuned.
Looking at the rear of the machine, we find a slew of changes!
On the left is the standard external floppy drive port, then the
monitor port (use your existing ST colour and monochrome monitors) and
even an RF modulator port for connection to a television. Next we find
the ACSI (Atari Computer Systems Interface aka DMA) port for connecting
external hard drives. Then there is the standard parallel printer port
followed by two modem/serial ports. The modem ports are of the DB9
variety though, so it's time to round up a new modem cable (IBM AT cables
work fine).
The much touted VME slot sits above the ACSI port and is currently
occupied by still another DB9 serial port. And on the far right is a
single internal fan (at last!) and two RCA phone jacks for stereo output.
Rounding out the package is the standard Atari two button mouse, power
cable, TV cable and a compact but very nicely written and illustrated
owner's manual of 170 pages or so. A standard 720K DSDD floppy drive
is incorporated into the machine. Sorry, no 1.4 Mb DSHD "superfloppy"
drive as yet.
UP AND RUNNING WITH TOS 2.5
~~~~~~~~~~~~~~~~~~~~~~~~~~~
At last we are ready to power up the beast. So plug in the power cable
monitor cable, keyboard and mouse and flick on the power switch. Uh-oh
Nothing happens. But wait 5 seconds and the hard drive reassuringly
begins to spin up, and soon initializes itself. Strangely enough, at this
point you press any key to continue autobooting from hard disk. If you
don't, the computer will pause for a minute and a half before completing
the bootup process.
NEW DESKTOP
~~~~~~~~~~~
When the desktop appears, you notice the icons look a little different
After some experimentation or browsing through the manual (heaven forbid)
you discover new icons can be installed from a generous library of pre-
designed icons. You can also instal any application on the desktop
as well as a handy printer icon.
Under the Options menu (figure 4), you find you can set default
directories, input parameters, and even function key assignments for
any application (all right!). Additionally, each drop down menu option
can be assigned a keystroke, of your choice. E.g. You could assign the
[S] key to activate the Show Information command from the File menu and
the [B] key to toggle the blitter graphics chip on and off. If all this
sounds familiar, it's evidence that Atari has kept an eye on the third
party developers of ST utility software as many of the new features
first appeared in programs like NeoDesk, MaxiFile, Hotwire et al.
Other new menu commands include a handy file search command and a
bottom to top command which reverse orders any existing windows on the
desktop. You can also Set File Mask to select the file type to be
displayed in the active window.
The View menu still forces all windows to be shown as either icons
or text, but you can now have up to seven windows open at once. Files
set to read-only status have little triangle next to them and you may
select all files in the current directory with a menu command.
Applications can be set to autoboot status and document types within
a specified directory can be linked to a given application. Multiple
NEWDESK.INF (equivelent to the old DESKTOP.INF) files can be selected
without re-booting via the new Read.Inf menu command. Trust me, there
are a lot of positive changes thanks to the new TOS 2.5!
The hard disk comes formatted in four 11.5Mb partitions with boot
software already installed. Users will appreciate this "plug and play"
philosophy. To boot from floppy just press [ALT] once as the machine
powers up.
NEW CONTROL PANEL
~~~~~~~~~~~~~~~~~
Explore the new Extensible Control Panel Accessory, which has been
lifted from the TT. The New Control Panel is called Extensible because
it supports up to 99 smaller programs known as CPX's or Control Panel
Extensions. Unlike desk accessories (still limited to a maximum of six)
CPX's do not have to be memory resident but will be loaded from disk
only when called. The Mega ST(e) comes with several CPX's factory
installed which manage window colours, CPX configuration, CPU speed,
stereo sound, mouse acceleration, modem and printer setup, etc.
At long last Atari has incorporated a battery backed up internal
clock -- set the time and date once with the Control Panel Accessory
- and forget it!
16MHz Spells F-A-S-T Relief
~~~~~~~~~~~~~~~~~~~~~~~~~~~
You may be wondering how the new 16MHz 68000 works in practice. Is it
appreciably faster? Is it crashworthy? Is it worth the extra bucks? The
answer dear reader is yes, Yes, and YES. From my thus far, limited time
with the machine I can definitely report that the cached 16MHz CPU does
a fine job of speeding up most applications, and has a very low bomb
rate. With the combination of 16MHz with cache on, Blitter chip, and
a software accelerator such as QuickST or TurboST, this puppy just flies!
Windows seem to SNAP open and scrolling text and moving blocks of data
around is visibly faster than 8MHz mode.
Knowing you won't take my word for it, I have created the following
benchmark figures with Darel Mihocka's Quick Index utility, ver 2.1. All
tests were based on TOS 1.0 as the reference point (100%) in medium
resolution colour.
SPEED TESTS ON THE MEGA ST(e)
----------------------------
8MHz 16MHz 16MHz 16MHz
w/cache w/cache
& QuickST 2.2
TEST
---------------------------------------------------------------------------
CPU memory 100 100 165 165
CPU register 100 100 204 204
CPU divide 100 183 204 204
CPU shifts 100 280 208 208
DMA 64K Read 5680 5853 5853 5680
GEMDOS files 1185 1185 1552 1204
TOS Text 102 108 174 601
TOS String 96 100 158 3208
TOS Screen 135 136 153 189
GEM Dialog 133 138 215 645
Numbers don't lie, but they can be misleading. Often a better
performance indicator can be made via the timing of real world tasks.
For example rotating an identical, large graphic clip under Migraph's
Touch-Up application required about 8 seconds on a 32MHz TT, 10 Seconds
on a 16MHz MegaST(e), and over 20 seconds on an 8MHz Stacey. Since the
MegaST(e) has a blitter chip and the TT does not, some tests may yield
surprising results. For example, using a version of the famous BOINK!
bouncing ball program, the Mega ST(e) with blitter chip enabled was
clearly faster than the TT. In all fairness however, a TT with fastRAM
installed and software written to take advantage of it, combined with
the 68030's cache, will surely blow the doors off a MegaST(e).
However if you intend to run strictly ST software, the MegaST(e) may
well be the clear winner from a cost Vs performance standpoint.
Spectre GCR users note: Version 3.0 works great on the MegaST(e) and
with 16MHz achieves a respectable Speedometer (a popular Mac benchmark
utility) rating of 2.15 faster than a Mac Plus. At 8MHz the rating drops
to 1.50.
Software Compatibility
~~~~~~~~~~~~~~~~~~~~~~
Basically, the MegaST(e) is an ST(e) with several new goodies added.
If your software works on a 1040ST(e) it will most likely work on the
MegaST(e) as well. The following list comprises some of the testing I
have done thus far: -
Programs that sometimes WORK
----------------------------
GFA Basic 3.5 Interpreter - Works with some conflict moving from immediate
mode to program mode.
GFA Basic 3.5 Compiler - Works but you must remove the extensible control
panel .ACC first.
Programs that do NOT WORK
-------------------------
Populous Twister 2
Programs that WORK
------------------
Aladdin ARC and LHARC Degas Elite DC Format 3 Dungeon Master
PC DITTO V3 Spectre 3.0 Test Drive WordWriter ST 2.0
Hardware Additions
~~~~~~~~~~~~~~~~~~
Modems: The DB8 modem ports cause some frustration to existing ST users
due to the need for a new cable.
Printers: Connecting a parallel printer is as easy as it ever was and
we now have serial ports as well. Atari has thoughtfully included a
screendump driver for use with the Atari laser printer.
External Hard Disks: Connecting your existing hard disk is as easy
as plugging it into the ACSI port and turning it on. ICD Host Adaptors
work without conflict when connected to the MegaST(e).
Monitors: You are currently restricted to the ST colour and monochrome
monitors unless you purchase an adapter and run a multisynch. This may
be a good choice if you plan on aquiring a VME graphics card at some stage.
External Stereo Speakers: With the stereo RCA phone jacks, running
your computer's sound output through your stereo system or a pair of
self powered bookshelf speakers is simplicity itself.
IBM Emulators: The square 68000 chip makes use of PC Ditto II all but
impossible. Supercharger should work fine as does PC Ditto I.
Macintosh Emulators: Other than the interference between the keyboard
cable and the cartridge, Mac Emulators like the GCR work just fine.
Accelerators: Fast Technolog's new Turbo20 accelerator will likely be
made available for the Mega ST(e) but you will have to judge whether
moderate gains in speed are worth the upgrade cost. It is till unknown
if Gadget's screaming SST 68030 accelerator will be made available for
the Mega ST(e) .
THE WRAP UP
~~~~~~~~~~
By and large, Atari's new Mega ST(e) is an impressive machine. It's
fast, highly compatible, and the new TOS and extensible control panel
enhance an already excellent desktop environment. We finally have a
great keyboard and the built in hard disk, VME port, and simple memory
expansion which improves the machine's usability and survivability.
Unfortunately, the ST(e)'s graphic capabilities are still behind the
times. According to reports both European and Canadian developers are
working on VME graphics cards for this machine so in time we'll have
at least VGA equivelent graphics with a 640x480 pixel display of 256
simultaneous colours. Then we can pressure Atari for affordable 24/32
displays of 16.8 million colours!
With the current prise war currently lowering the cost of the 1040ST(e)
the Mega ST(e) may seem overpriced. However, compared to the cost of
cobbling together a system to approximate the Mega ST(e)'s features the
price is attractive. In fact, one of the nicest features about the
Mega ST(e) is how seamlessly everything is integrated. After having
to strap bits and pieces into and onto my old 1040 ST with baling wire
and bandaids, it's really nice to have a clean setup again. Like the
man says, "You want it? It's in there".
So take a good long look at the new MegaST(e). Better still try to
arrange a test drive. You are sure to come away impressed and confident
that Atari still has what it takes to make a great computer.
