AmigaOS 3.5
Developer: Haage & Partner/Amiga Inc.
Announced: October 1997
Released: October 2000
Sales: 13,000+ |
After a long and turbulent development period AmigaOS 3.5 was
finally released during October 1999. It was the first operating
system upgrade in 5 years, improving support for modern
hardware and implementing new functions to supplement the core OS.
Numerous hacks that had supplemented the OS over the years
(NewIcons, etc.) were made obsolete or moved into officialdom
(WarpOS). Support was added for 4Gb+ hard drives and NSD
devices.
Boing Bag
The release also introduced a series of official updates, known as
BoingBag releases, that repair problems that may have arisen or
improve system speed when using 3rd party applications.. These can
be downloaded from the Amiga OS3.5 area on the Amiga web site.

The Future (Plans & Options)
Although the development of Amiga OS3.5 was placed in jeopardy,
Haage & Partner gave an indication of what features they would
like to include in the OS updates that followed. These features do
not reflect the contents of Amiga OS3.9, but suggest that an Amiga
OS4.0 release was on the cards.
- Further releases or add-on packages
- New reworked and extended Kickstart
- Extended PowerPC support
- New 68K Emulator for PPC-only systems
- Many new System Libraries as PPC-native
Criticism
The release of AmigaOS 3.5 has stirred great controversy in the
Amiga community. This is hardly surprising, five years of
abandonment has led many to upgrade their system in any way they
could. Expectations of the update would never have been filled. In
particular, four issues have been raised. These complaints seem
minor in comparison to the benefits of using OS3.5.
1) 68020 as a minimum
Many users' complained that the operating system require a 68020
CPU as minimum. The logic in their argument is unclear, why would
anyone that owns an unexpended A500/A1000/A2000 want to upgrade to
OS3.5. There are few benefits and the new eye candy will make their
machine slower.
The objections raised appear to stem from the inability to run the
OS on every Amiga that has ever existed (this is the first AmigaOS
upgrade that has not been able to run on the A1000). As a
comparison to highlight the lunacy of these comments, Apple have
dropped support for the 68k and early PowerPCs altogether. A500
users with 0.5Mb cannot expect their 10 year old system to remain
at the forefront of development.
Decision: Amiga Inc. were right to move the
boundaries.
2) Software-only Update
Since 1994 the Amiga has changed considerably, PowerPC, graphics
cards, and many other features have become standard. These have
highlighted existing problems in the existing Amiga architecture.
In particular, many Amigans complained that OS3.5 did not include a
ROM upgrade, as was expected. This would have instantly solved some
of the problems experienced when using new hardware, such as
syncing early bootup screens to a 31KHz display and ROM support for
hard drives larger than 4Gb. In place of a new OS3.5 ROM, Amiga
Inc. wrote a software patch (dubbed the 'Jumpstart functionality
set' that installs itself on bootup, and provides software support.
However, this has not fixed some issues that exist in the ROM
itself, such as the aforementioned problems with the early bootup
screen.
Decision: An unfortunate omission but
understandable
3) Retargetable Audio and Graphics
Early statements on OS3.5 indicated that Retargetable graphics and
sound was to be included as standard. Retargetable audio was
planned through the use of a new audio system called ARTAS. This is
an AHI-compatible system that supported, among other things,
streaming sound. However, the required effort needed to implement
RTG and RTA, and the repeated cancellation of the OS3.5
project, led to its abandonment. These have made an appearance in
the OS3.9 update, through the use of third party software.
Decision: Again, unfortunate, but
understandable omission.
4) ClassAct/Reactor-based GUI (Graphical User Interface)
as standard
The fourth and final complaint about OS3.5 regards the use of
ClassAct to build the user interface. ClassAct was renamed
'Reactor' replacing the ASL standard interface. Many hated it for
its lack of features in comparison to the toll it takes upon system
performance. In comparison to ASL, it is slow on a low-end machine
and lacks the customization provided by MUI (Magic User Interface).
Its choice was explained by Holger Kruse on the Team Amiga mailing
list:
The decision to use ClassAct was made a long time ago. Look
at it this
way: they had to use *something*. There are not all that many
choices:
BGUI is too buggy, their own first choice StormWizard is not
powerful
enough and not supported by developers. GadTools-based
solutions are
too slow. MUI is probably too controversial, and also rather
large
and on some systems too slow.
Also, MUI moves away from the Holy Grail BOOPSI/gadgetclass,
making it
more difficult to make further changes or extensions to the
object
model in the future. In a way, a decision in favor of MUI would
have
been a "bigger" decision, more difficult to reverse or change
in the
future, and with much wider implications, than a decision for
ClassAct.
Personally I VERY much prefer MUI over ClassAct, for
fundamental design
reasons, and some reasons rooted in computer science, but of
course I
did not have a say in the matter :-)
And, of course, once the decision for ClassAct vs. MUI was
made, most
choices regarding other applications automatically fall into
place,
e.g. the browser decision. Popularity does not enter into this
at all.
Decision: Make your own decision
