PRODUCT NAME
Amiga A3000T-040
[MODERATOR'S NOTE: This review was updated slightly by
the author on May 3, 1993, to add a new timing result.

BRIEF DESCRIPTION
Amiga A3000 in a tower case with pre-installed A3640 (68040) card.
AUTHOR/COMPANY INFORMATION
Name: Commodore Business Machines
Address: 1200 Wilson Drive
West Chester, PA 19380
USA
(Varies for other countries)
Telephone: (215) 431-9100
LIST PRICE
The list price has recently been reduced to about $2700 (US). I got
mine at a special price as a Commodore developer.
SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
The system came with a pre-installed A3640 card, 4MB of fast RAM and
1MB of chip RAM. It came with a preformatted (with Workbench 2.0.5) Seagate
240MB drive and one high-density (HD) floppy.
I added a second internal HD floppy drive, an A2286 Bridgeboard, an
A3070 tape drive and an A1960 monitor. I also transferred my Quantum 105MB
drive and 14.4K Practical Peripherals modem from my A1000. In addition, I
added 4MB of Fast RAM, another 1MB of Chip memory, and installed Workbench
2.1.
BACKGROUND READING
Since the Amiga 3000T-040 is an A3000T with a 68040 card, I
recommend you read Dan Barrett's previous reviews of the A3000T. They are
available in the c.s.a.reviews archives on math.uh.edu, and they have a lot
of relevant material which I will not repeat here.
WHY A3000T-040?
My computing needs have recently outgrown my Amiga 1000, so I started
exploring upgrade paths. My considerations were: an A4000, the A3000T-040,
a '486 clone, and a SPARCClassic. I ruled out the '486 since that would
require new software and learning a new architecture; and with the new
pricing on the Amigas, the savings would not be much. The SPARCClassic was
next to leave the list. While the new base machine is fairly inexpensive,
the cost of hardware necessary to utilize it fully plus maintenance and
repair proved too high. That narrowed it to an A4000 or an accelerated
A3000. The only thing the A4000 offered that the A3000T-040 did not was the
new chip set and higher graphics speeds (see benchmarks, below.) For the
price of not having the latest machine, the A3000T-040 offers more expansion
capability and a real SCSI port. The only other option I considered was
waiting for the A4000T, but I really couldn't wait much longer, and I
imagine the A4000T will be priced significantly more than the reduced
A3000T-040. So, I placed my order for the A3000T-040.
SETUP
The A3000T-040's box contains a bag of parts labeled, "Open
Immediately." Inside is a note that says to put the enclosed SCSI
terminator on the back SCSI port before turning on the machine. It worries
me that one might easily overlook this little warning and have trouble later.
Also included was a note telling me to install the 68040.library
immediately. A 68040 support disk was included with a neat install script
that worked fine.
After turning on the machine and making sure it all worked, I
proceeded to take it apart and install my expansion devices. I used the
hints in Dan's review to take off the front and side panels. (I recommend
reading that review, since the manual does leave a few things out.) The
first thing that I noticed is that the motherboard does not have the 68030
and 68882 that other A3000s have. The A3640 card is in the CPU slot and
held down by two screws. This must be removed to install fast RAM. I made
myself a groundstrap from a length of speaker wire and set to work. One
must be careful, but the RAM installation is easily done.
I then started to install the the second floppy drive. Here I faced
two problems. First, the screws needed to hold the mounting bracket to the
tower were not included in the bag of parts; and second, no instructions
were included with the drive. So when I got the screws myself and installed
the drive, I could not get the machine to recognize both drives at the same
time. I fixed the problem by changing a jumper on the new drive from the
DS0 position to the DS1 position. Note that there is a jumper on the
motherboard marked DF1 and NO DF1, but it was recently posted to the net
that this jumper is not relevant to the HD drives. Perhaps it is for the
standard drives -- I don't know. Also missing from my bag were the screws
for the Tower's feet and for the 5.25" bridgeboard drive. Commodore
eventually sent me the feet screws along with the "Quick Installation"
poster that I was missing. I managed to assemble the system without it. By
the way, you must take both side panels off to install the floppy drives.
The bridgeboard and drive went in easily, though I still can't get
the floppy to work. I suspect it is a bad drive, as I did get a borrowed
drive to function properly. Sigh. The biggest challenge, I thought, was
going to be the installation of my old Quantum drive from my A1000. I was
not sure if I would be able to take the drive off my A1000 controller and
have it accessible on another. It actually turned out quite easy, though.
I mounted it with the supplied "HD stacking brackets" over the internal
Seagate drive and used my old mountlist entries to mount my three separate
partitions. To my surprise, they mounted the first time (after changing the
device name), and all my files were there. I then tested the A3070 by
backing up the drives, and used HDToolBox to reformat them and the A3070
(via Quarterback 5.0.3) to restore them. It all worked fine.
The only real tricky installation process is the installation of the
hard drive shelf, as Dan mentions in his review. His hints, however, were
quite helpful and sped up the process enormously. I made the mistake,
though, of trying to figure it out myself before re-reading his hints.
The installation of 2.1 over my existing 2.0.5 Workbench was
simple. I just used the install script and it replaced everything it needed
to, got rid of anything obsolete, and left everything else alone (especially
SPEAK: and Say.)
ADDRESSING DAN'S CRITICISMS (from his review)
The internal fan: I don't find the fan noise intolerable at all.
It is audible, but not disturbingly so. Either I have an improved fan or am
not as sensitive as Dan. It is louder than my A1000's fan, but much quieter
than the hunk-of-PC on my desk at work. The unit is standing on the floor
facing me at the end of my desk -- about two feet away.
The speaker: I have not really employed it much, so I can't comment
on it yet.
Locking up during crashes: I have had only a few crashes and all of
them resolved with the three-finger salute. I've been quite happy at the
fewer number of GURUs. I've had the machine on almost continuously since I
got it. No major problems there, either. I guess the real test will be this
summer when it is significantly hotter here in Texas. The machine is
remarkably stable. (And Mindwalker still works!)
SPEED AND BENCHMARKS
Since one of my primary needs was a faster CPU, I set out to
benchmark the system. My work entails a lot of floating-point intensive
operations. I installed Manx C5.2a (they say version 5.3 will support
inline math functions that the 68040 needs) and my old version of Absoft
Fortran. Both seemed to produce valid code -- though the Fortran compiler is
certainly not optimized for the new breed of Amiga CPUs. I used these
compiler to run some of my standard codes and timed them compared to the
SPARC stations I use at work. I would compare them to my A1000, but I have
disassembled it, and the thought of setting up the compilers on a
floppy-based system is no longer ap
