PRODUCT NAME
DP IBM Analog Joystick Interface
BRIEF DESCRIPTION
The DP Interface is a hardware converter that allows the use of
analog joysticks on the Amiga, for programs that recognize standard IBM
analog joysticks.
AUTHOR/COMPANY INFORMATION
Name: DigiPrint, Inc.
Address: P.O. Box 13016
Richmond, VA 23225
USA
Telephone: (804) 560-1769
LIST PRICE
$15.95 (US)
SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS
HARDWARE
Requires an IBM compatible analog joystick.
SOFTWARE
None.
COPY PROTECTION
None.
MACHINE USED FOR TESTING
Amiga 2500, 25 MHz 68030/68552/68882
2 MB Chip RAM, 10 MB Fast RAM
Kickstart version 37.300, Workbench version 38.35
Advanced Gravis Analog Joystick
INSTALLATION
Extremely easy. All you need to do is plug the joystick into the
DB-15 end of the interface, and then plug the 9-pin end of the interface
into port 2 (joystick port) on the Amiga.
REVIEW
While playing my favorite flight simulators, I noticed that there
was a performance barrier caused by the software. After many phone calls,
and some personal research, I came to the conclusion that it was a hardware
restriction, and decided to pursue getting an analog joystick for my Amiga.
Looking for analog joysticks for the Amiga is like trying to find hard
drives for the Commodore 64: possible, but not likely. Enter the DP IBM
Analog Interface.
With an analog joystick, you can experience the realism built into
the software which is unavailable to digital joystick users due to the lack
of sufficient input parameters. Using an analog stick requires a new
mindset about programs that support them. For example, you can align the
joystick manually for best performance (see next paragraph). Once properly
aligned, the analog joystick gives a sense of feel and control that more
accurately mirrors the actual response to a real joystick in a real plane,
at least as far as the program is concerned. I tried the analog versions of
several games, and found some amazing differences, as well as some astounding
conundrums.
To align the joystick, you first set a 3-position impedance-matching
slide switch, which allows for rough calibration. Next, you trim the pots
on the X and Y axis yokes with a nonconducting miniscrewdriver until you are
either straight and level, or the setup program shows you zeroed for stick
center.
Below is a tabulation of my results with a few programs supporting
the analog joysticks.
Fighter Duel Pro Flight Recorder
Works well in all switch positions, and the stick recenters
accurately, although there is no provision for calibration or
feedback.
A-10 Tank Killer (Version 1.5)
This was the second most consistent and stable program tested.
The preferences menu has joystick analog/digital and calibrate
joystick, and it works well. This is by far the most elegant and
straightforward implementation yet tested. This program MUST
be run from a hard drive with an accelerated machine, and/or
with analog joystick mode selected. I chose graphic mode 5 -- full
64-color with autodither -- and found the frame rate acceptably
smooth and accurate. Stock machines running the 68000 CPU at
7.14 MHz wouldn't be able to control the game, even at graphics
level 1. I know: I tried and found it unacceptable.
Flight of the Intruder
This rather lame flight simulator has a first-rate analog joystick
calibration program, enabling you to accurately set the proper
switch position on the interface, and the trim pots as well.
Knights of the Sky ("KOTS")
This great flight simulator is hampered by the fact that to use the
analog joystick feature, you must disable any accelerator or
advanced processor that is present. This was with the CBM A2630
with 4 MB of RAM, and a DKB 2632 with 4 MB RAM. This is rather
odd, as DP is the official interface of MicroProse, and MP is
known for producing excellent and well-behaved programs. I don't
know what the problem is, but both DP and MP said that some
accelerators don't work well with this combination. Oh well.
F-15 Strike Eagle II
Same as with KOTS, except the accelerator made the program hang.
Sound kept on going, but the graphics just froze. So no
acceleration for those wanting to use MP games with analog
joysticks. Seems like this could be remedied by MP, IMHO.
Birds of Prey
While no specific commands, menus, or keyboard hotkeys activate
the analog joystick, the game does appear to autosense the input
device, and auto-center as well. While handling is greatly
improved, targeting and landing are significantly more difficult.
After you are done experimenting with settings for a particular
program, I recommend creating a README file to remind you of the best
settings to use, as I have.
DOCUMENTATION
The instructions come on a 5x7 inch, single-sided sheet that is
pretty straightforward. There is even a recommended list of sticks which
includes all but the Kraft Thunderstick and the Thrustmaster, since they
require a special card inserted in an IBM 8 bit slot. I doubt if these two
sticks would work on the Amiga side of a Bridge Board setup, although I've
not tested this idea.
LIKES AND DISLIKES
I like the basic product, and wish it had support for the use of
rudder pedals. Rudder pedal support comes from their DP IBM Bus Mouse
Interface, which also allows the use of 400 DPI mice. What I'd like to see
is a product which incorporates both of these devices. The bus mouse
interface retails for $9.95 US, and an order form comes with the DP joystick
interface.
I also like the support staff; see VENDOR SUPPORT, below.
You won't be disappointed with this product, and upgrades are
promised in the future to support the CH Flightstick with the "Coolie Hat,"
but no time frames have been given.
COMPARISON TO OTHER SIMILAR PRODUCTS
The only other competition is the Amiga Smart Port from IDD. For
almost four times the price, it allows the use of rudder pedals, and the
coolie hatted CH Flightstick. For the money, you just can't beat the
combination of mouse and joystick interface for full analog joystick, and
rudder pedal use.
BUGS
NONE
VENDOR SUPPORT
The support staff are all Amiga, and are very loyal to their users.
They are very enthusiastic, receptive, and knowledgeable. As they are now
the official MicroProse analog interface, I am hoping for better support of
those users running faster machines than a box stock A500. What with
A3000's and A1200/4000's out in greater numbers, it seems a rather sad
commentary on the state of Amiga software vendor support when they go for
commonality rather than excellence, as is found in the IBM world.
The vendor asks for ideas, and will share some of its profits with
anyone whose ideas that they adopt into production. This is my kind of
company!
WARRANTY
90 days on parts and labor, from date of purchase.
CONCLUSIONS
This is a great product for the money, with lasting value and
usability. I would urge all flight simulator fans strongly to consider the
DP interface, just to see the amazing difference it will make in your playing
enjoyment. While I haven't tested the IDD interface for comparison, I feel
that for the money you won't find anything better anywhere, AFAIK.
