OK, so last night my dad set up his old Amiga 1200 (which has been 
somewhat modified), and we played some games.

Unfortunately, attempting to play Zyconix resulted in an immediate Guru 
Meditation Number. (Who the hell came up with THAT name??)

I spent some time playing a game known only as "Putty". This is actually 
the first Amiga game I ever saw, running on my dad's Amiga 600. Try to 
imagine my reaction: It's the early 1990s, and I've spent most of my 
life playing games on a Commodore 64. And then I come home one day and 
find everybody sat round the TV, playing this thing.



For those who don't memorise such details, let me throw in some 
technical specifications.

- C64: 16 colours available, up to 16 on-screen at once. (Like old VGA.)

- A600: 4,096 colours available (!!), up to 32 on-screen at once.

- C64: monophonic subtractive synthesis, 3 notes polyphonic.

- A600: stereophonic digital playback, 8 bits/sample, arbitrary sampling 
rate (i.e., not just a choice of a few preset rates) up to over 50,000 
samples/second. 4 independent channels. Hardware sample looping.

The A600 also boasts lots of tricks and gizmos that can be used to work 
around these limitations to give even more impressive results.

In other words, in principle the A600 can produce almost photographic 
images, and nearly CD-quality sound. These levels are seldom reached in 
a *game* though - it has to fit on a reasonable number of double-density 
floppy disks.

(Double-density being the 800 KB disks that came *before* the 
high-density "1.44 MB" disks we use today - so it's actually more 
limiting than it sounds. And JPEG wouldn't be invented for another 
decade or so yet - even if there were a machine powerful enough to 
handle it!)

In practice, on a cheap CRT TV with blurry picture and weak sound... it 
looked damned-near photographic and sounded very impressive. Certainly 
obliterating anything the C64 could muster, by a significant margin.



As some kind of comparison, take a look at the C64 classic "Uridium":

Now compare to "Putty":

http://www.mobygames.com/game/amiga/putty/screenshots/gameShotId,33172/

You can see why I was so damned impressed! The hike in graphical quality 
is very significant. Check out the Putty logo screen:

http://www.mobygames.com/game/amiga/putty/screenshots/gameShotId,33168/

With a tiny amount of blur the dithering and aliasing isn't really 
apparent, and it *appears* to be a hyper-snooth image.



Putty is a platform game. Once you get over the fact that it's a 
platform game, and how old-fashioned and boring that seems and just PLAY 
the game for what it is... it's actually quite interesting. Even today. 
Obviously the graphics are rather blurry, and the sound is mildly grainy 
in places - but it's not nearly half as bad as you'd expect. It's 
actually quite *good* in fact.

The game involves controlling a small sphere of blue putty. It has two 
eyes, and when it moves, the underside develops two small lumps like 
"feet". It's quite comical to watch. It can also jump, and stretch short 
distances. This little guy manages to be surprisingly expressive; he's 
only got eyes, but with just his eyes and eyelids he manages to convey a 
seemingly wide range of emotions.

Controlling this lump, you must do battle against various foes. There 
are small red and white mushrooms with eyes that jump around 
rythmically. There are little snails who's shells jiggle up and down as 
they saunter along. And so forth. There's an organce carrot with a green 
spikey hairdoo who yells "uzi ninty millimeter" in a chipmonk-style 
voice and fires bullets at you. And various kinds of birds and bird 
chicks flying or waddling around.

Most of these can be killed by "absorbing" them. Press down and the 
putty ball plattens itself over the floor. Anything that steps on the 
sheet of putty gets absorbed, causing the putty to return to its normal 
ball shape.

Certain enemies can also be "punched", which turns them into little pink 
babies (together with a rythemic "wah! wah! wah!" sound). If you absorb 
these, you get additional points. If you're not quick enough, they 
eventually vanish. If you don't quite get there in time, a cat's head 
bursts through the platfield (as if it were paper), and a grainy sample 
plays: "Too bad, juuuuuust missed em... HAHAHAHAHA!"

[It appears to be a sample of Screwy Squirrel. I saw the cartoon 
broadcast about 10 years later while casually watching TV, and he said 
that exact line.]

The spatial resolution isn't so hot, but even today the colouring looks 
pretty smooth. My dad's composit video lead seems to introduce a lot of 
ghosting - maybe it's not shielded right or something. But I'm playing 
this game on a *vast* 40-inch LCD panel, and the colours look smooth and 
seemless, even if the edges look rather grainy. The putty is a deep 
blue. The mushrooms are red and white. The snails are bright green, with 
golden brown shells. And so forth.

It all looks very smooth and slick. More to the point, every single 
individual character is just *packed* with character. They all have 
their own characteristic movement. The whole screen is so full of life, 
it's really quite entertaining just to watch.

The sound is pretty neat too. If the putty touches another creature, it 
makes a strange "squawking" sound, and it's eyes bulge. However, when 
the putty absorbs a creature, you get a combination of a high-pitched 
"plink" and a burp. When you complete a level, you hear a bubbling sound 
followed by a coocoo clock. It's all quite zaney and strange, but it's 
once again full of character. (And a far cry from the bleeps and buzzes 
the C64 can manage.)



Eventually I got frustrated with Putty. (Although I did play it for a 
rather long time.) My dad's joystick seems to be slightly worn out. 
(Hey, when was the last time you heard the word "joystick"? Much less 
*used* one...)

I spent some time playing "Cool Spot". But that was just annoyingly 
difficult to control.

Another neat game is "Push Over". This involves domino puzzles. You 
start a level with a given configuration of dominoes, and you have to 
rearrange them in such a way that by pushing a single domino, all the 
dominoes fall. Once every last one has toppled, the level exit door 
opens. But you've got a time limit, and various dominoes have "special" 
features - they're impossible to knock over, they have a delay before 
they fall, they continue to roll over and over forever, etc. It's great 
fun, and the later levels are *definitely not* a push-over!

But then I cound an old CU Amiga coverdisk, containing the full-version 
of the very excellent shareware game "Cybernetix". This is your standard 
"you fly around in a space rocket shooting asteriods" type thing - but 
done *well*. Watch out for the enemy ships trying to attack you!

http://www.mobygames.com/game/amiga/cybernetix/screenshots/gameShotId,254396/

I most especially like the music too. I think I'm going to have to wheel 
my CD recorder round to my dad's house to make some serious recording! I 
used to have a tape somewhere, but I've long since lost it, and most 
games won't run on my heavily modified Amiga any more. (In particular, 
I've got the updated Kickstart ROM.)



While we're on the subject, the Amiga 600 features the Enhanced Chip Set 
(ECS), which is a slightly improved version of the Original Chip Set 
(OCS) as found in, say, the Amiga 500. However, the Amiga 1200 features 
the formidible Advanced Graphics Architecture (AGA). Let's compare specs:

- ECS: 4,096 colours available (i.e., 4 bits per RGB channel), up to 32 
colours on-screen at once using normal indexed bitmaps. (Various special 
tricks allow far more, but with restrictions.)

- AGA: 16,777,216 colours available (i.e., 24-bit colour like on all 
modern video systems). Up to 256 colours on-screen at once using normal 
indexed bitmaps. (Again, lots of special tricks available to exceed this 
limit, some of them unsuitable for games programming.)

With enough preprocessing, an AGA Amiga can basically display 24-bit 
graphics. It just has to be encoded cleaverly. Recall that at this point 
in history, PCs were still lumbering around with EGA or maybe, if you're 
lucky, VGA. Ooo, 16 colours. Wow. :-P

Oh how we laughed at those silly little PCs with their lame-ass Windows 
3.11 that struggled to open and close windows when we had a true 
premptive multitasking OS with a lightning-fast GUI and hardware with 
high-quality digital audio and video.



Unfortunately, then the Amiga's hardware stood still for 20 years. While 
it was once a shining example of hardware far ahead of its time, it has 
long since been left in the dust. I don't really understand how it 
happened, but Commodore ended up in all sorts of financial trouble. 
Commodore was good it making great hardware, but hopeless at marketing it.

(Having said that, there was one cheeky thing they did. They put a 
30-foot poster showing an Amiga CD32 - directly outside Sega's UK 
headquarters. The caption read "To be this good will take Sega ages". 
The Amiga CD32 is basically an Amiga 1200 with a CD-ROM drive.)

There were persistent rumours of a new chipset dupped "the AAA chipset". 
(I forget what that's meant to stand for.) If the rumours are to be 
believed, they had "running silicon" for a true 24-bit graphics 
subsystem. That is, it could display 16,777,216 colours at once without 
trickery. It also had hardware to copy and combine graphics blocks 
without CPU intervention, and various other sophistications.

Reputedly the sound hardware got a tweak too. (The sound capabilities of 
the OCS, ECS and AGA were all identical.) Details of this were scant though.

Month after month, Amiga magazines [of which there used to be many] 
phophesied new hardware hitting the shelves "soon". Ultimately, this 
never occurred. It was a very upsetting time for us all.

Then, one by one, all the Amiga magazines shut down. I still remember 
the day CU Amiga shut down, and Amiga Format promised that "Future 
Publishing is in a different position to CU Amiga, and we can promise 
that AF wil never shut down". A year or so later, when AF had become 
little more than a thin pamphlet, they finally announced their decision 
to shut down.



Looking back through the pages of old issues of AF, it's amazing what 

for a device called a "digitiser" which transforms analogue sound into 
the digital form that the Amiga can then play back. (Modern sound cards 
throw this in for free!)


sound editing package. TechnoSound Turbo even came with a minimal 
sequencer! These packages would load and save multiple file formats, 
edit sound down to the sample level, program in sample loops, apply very 
basic filtering and so forth.

Then there were ground-breaking AF coverdisks like Imagine 2, Real3D, 
Expert 4D Jr, Cinema 4D, et al. Most of these just render polygons with 
texturing and light sourcing, but Imagine offers configurable procedural 
textures, and Real3D offered sophisticated *ray tracing* and CSG. The 
more expensive machines (the ones that *didn't* appear as cover disks) 
offered particle systems and inverse kinetics, and so on and so forth.

It sounds old-hat now, but seeing for the very first time a home 
computer produce a realistic 3D image out of nothing was a truly 
astonishing thing. Sure, Hollywood had been doing it for a while. But a 
home computer? A *home* computer?? Wow.

(Bearing in mind, my first ray-traced scene - a mesh torus with a 
procedural wood texture and one light source - took well over 2 *hours* 
to render at 320x200 pixels. What can I say? No FPU...)

Then there were coverdisks and commercial programs for drawing fractals. 
Fractuality was famed. I actually got to own this one. I played with it 
on my dad's Amiga the other day. It took 30 minutes to laboriously draw 
a Mandelbrot image - you could actually watch the individual pixels 
appear near the edge of the set, while further out it was quite fast.

The program comes with a complement of demo parameters. Some of them I 
couldn't actually see, because the rendering was just so ridiculously 
slow. Watching my dad's Amiga struggle to produce this image yesterday, 
I realised that it's not even a particularly deep region. Xaos zooms 
past it IN REALTIME on my 2.4 GHz Athlon64 X2 at home! How far we have 
come...



Then there was Amiga Format's landmark inclusion of several versions of 
OctaMED over the years. Originally some Finnish guy (why was it always 
Finnish guys?) write the Music EDitor, MED. Then, alone amounst the 
"tracker" genre of programs, he added *8 channel mode*, thus creating 
OctaMED.

This breakthrough feature essentially uses software upsampling and 
mixing to play 8 independent channels of sound even though the Amiga 
actually possesses a mere 4 hardware channels. The result brings an 7 
MHz Amiga 600 to its knees. (It's quite tame on a 12 MHz Amiga 1200 though.)

The software gradually become a commercial enterprise, and feature after 
feature was added. A very early and unique feature was a simple 
software/hardware "synthesizer" engine. No other tracker had it. Also 
MIDI support, unique amount trackers.

But then, the astonishing OctaMED Sound Studio came out. This completely 
tore up the rulebook. Unusuable on anything less than an Amiga 1200, 
this allows an *unlimited* number of channels! And each with *arbitrary* 
stereo location! And many of the tight restrictions from OctaMED's 
8-channel mode were removed. And Amiga Format put this legend of sonic 
power on a coverdisk!

In the blink of an eye, suddenly if you had the CPU and the storage 
space, you could record chunks of digital sound, edit it, and produce 
complex, layered symphonies of sound. And in another astonishing move, 
OctaMED Sound Studio allows rendering *to disk*. So if you happened to 

real CD* out of your music! Previously this was an unthinkable achievement.

Using more than about 20 channels started to slow the system down quite 
a bit (especially if you were really *using* all those channels), but 
the possibilities seemed vast. If nothing else, now you could load up 
all your old songs and edit the stereo staging to sound less irritating. 
Suddenly you felt like a "real" musician!



It all sounds a bit silly today. We tak such things for granted. Look:



- The cheapest, nastiest motherboard you can buy is virtually guaranteed 
to have 52-channel super-hyper-mega-ultra surround sound, and will have 
analogue and maybe even digital audio *inputs* as well.

- *All* graphics cards can trivially display 24-bit graphics. 
Specialised high-speed bitmap copying hardware is unecessary due to the 
speed of the other components.

- Sophisticated image processing software such as The GIMP can be 
obtained *for free*!

- 3D graphics rendering requires nothing more than a copy of POV-Ray. 


- Complex sound editing software such as Audacity is *free*.

In fact, it seems that only high-end, professional audio and video tools 
actually cost money any more. (I'm thinking... Cubase, Cakewalk, 
Photoshop, Renderman, and so forth.)

Today, anybody with sufficient technical bent can easily sit down with a 
computer and cut CDs of their music, or burn DVDs of their graphics and 
animations. It's not even expensive any more.

We are truly living in the future, my friends...

The management at Commodore should take all of the blame for the fall of 
Commodore.  Developing killer new technology should have been top 
priority.  Hindsight being 20-20, they should have designed the OS with 
the highest possible degree of resource management (IE, not assume that 
all graphics would be 8-bit forever), and then opened up the hardware 
architecture and allowed clones.

As it was, some of the later CEOs did nothing more than collect their 
salaries.

What? Back in 1990 I had a PC with a VGA and it could display 256 (out 
of 262,144) colors at 320x200. It was a Paradise card, so it could 
actually do 256 at 640x480, 16 at 800x600. Of course, sound was 
non-existent on the PC platform. I eventually had an Adlib card, which 
used the Yamaha OPL synthesis. I'm pretty sure I had this in 1991. 
Somewhere in the early to mid 1990's I discovered the demo scene, which 
did some pretty amazing things. There was a tracker called ScreamTracker 
3, which could mix 16 channels at once (It was all done in CPU, of 
course.But, you had to have the SoundBlaster, which allowed digital 
sound) There was a player around that actually tricked the AdLib into 
playing actual sampled sound. It was amazing. Of course, with a few 
resistors, you could have something that would natively play sound out 
of the parallel port.

I'll agree, Windows 3.x sucked. :)

POV-Ray was why I sought to by a math-coprocessor. Remarkable speed up 
of that app. ;)

Yep. I like GIMP. It makes a passable substitute for Photoshop when I'm 
not at home.

If you've ever really used Photoshop, some things that are trivial to do 
in that program all the sudden become very difficult in other programs. 
Remember that video you posted on the making of that webcomic. That was 
PS. I've taken old faded pictures (some with missing pieces, where the 
emulsion was scratched or torn away) and brought them back to their 
original color, replaced the missing pieces, and got rid of the texture. 
  It would have taken me days to do that with GIMP. It only took a few 
hours in PS. Not only that, but the sometimes drastic color correction 
was performed without much degradation, due to the fact that I can 
import and edit in RGB16 instead of RGB8. There are advantages to the 
expensive packages ;)

Heck. You can do this for free, too ;)

Looking on Wikipedia, the Amiga A600 was introduced in March 1992.

In September 1991, Acorn launched their A5000 that had a processor with 14x 
more MIPS, up to 256 colours on screen at once at 800x600 with no special 
trickery, 8 independent sound channels that could be assigned to any stereo 
location, 8 bit logarithmic DACs that sounded like 12 bit (apparently) and a 
high-density floppy drive as standard (1.6MB).

There again, it was twice the price of the A600...

I was always astounded that "66 MHz" PCs would crawl along unbearably 
slowly while my little "14 MHz" Amiga 1200 ran rings around them. It

actually *believed* that the numbers weren't lying. The Amiga just

Oh hell yeah. I can remember adding a 20 MHz FPU to my Amiga and 
watching Fractuallity suddenly get an order of magnitude faster. ;-) 
"Wow, it's so fast!" I cried.

Watching it yesterday, with FPU and all, there didn't seem to be much 
"fast" about it!

I'm sure. (E.g., colour seperations...)

I own Photoshop Elements now. It's not very impressive.

I have no idea how that's even theoretically possible.

I won't deny that. ;-)

Well, let's be fair here. The Amiga 1200 already has 24-bit colour and 
up to 12 bits per pixel. And it's still register compatible with the old 
chips.

If you had the money, there *were* in fact boards like the famous 
Piccaso that give you true 24-bit graphics. (Damned expensive though!) 
All "properly-written" applcations would transparently use this without 
even knowing it. What more resource management do you want?

The *problem* was all those games that bypass the OS and hit the metal 
directly to wring every last drop of speed out of the system. 
Unsurprisingly, as soon as you change any hardware, all your games 
break. (Or at least the vast majority of them.)

Apparently so.

Depends. Small tears and missing chunks are really easy using clone and 
heal tools. Larger tears and missing chunks require a more "creative" 
approach. See the attached images.

Well, assuming you already have the PC... If you don't you can still 
accomplish your goal for under $1000.

I've seen someone actually make a pretty impressive short film using 
Windows Movie Maker and a $50 pocket camera.

The Amiga 1200 offers up to 256 colours at once, no tricks. It was 
released in Oct 1992.

(The Amiga also offers even more colours if you use special tricks, 
ranging from the simple ones that impose very few limitations, to 
complex ones that are only really useful "for show".)

The resolution doesn't really compare, but the Amiga was targetted at 
normal TVs. The Amiga's 640x480 is quite near to modern DVD's 720x564.

> There again, it was twice the price of the A600...

Heh. Yeah. ;-)

And I'm sure if you pay even more money, you can get better specs. 
Predator was released years earlier and featured some impressive 
computer graphics; that computer had to come form somewhere. But 
certainly you wouldn't find one in somebody's *house*!

Thing is, up until this point, computer graphics had always been blocky 
things made out of a dozen flat colours. Computer graphics *looked* like 
computer graphics. Computer sound *sounded* like computer sound. And 
then suddenly there was this amazing machine that seemed to produce 
pictures and sound that were drastically closer to reality... it was a 
very exciting time!

These days, nobody really thinks about it much. Heh, the digital 
revolution isn't "here", it's "happened". Nobody even talks about it any 
more. ;-)

What amazes me about the Amiga is how frequently it was used for digital 
effects in a number of TV shows. I just skimmed the Wikipedia article. I 
guess at some point they were running Lightwave, which is a very 
expensive professional rendering package, on it.

I got it free with my shiny new Wacom tablet. ;-)

OK, that's just absurd. The sofa and the rug are *exactly* the same 
colour. How the hell can the machine tell them apart? Additionally, how 
on earth can it tell what colour they were originally? That's impossible...

Well, yeah. I mean, if you just want to render some 3D scenes with 
POV-Ray and stick them on a DVD, you don't even need that much. You can 
probably buy a PC with a DVD burner and some movie authorising software 

anything with such a slow CPU, but if you wait long enough it'll do it.

That makes no sense. I can't get Windows Movie Maker to do *anything* 
useful...

(But then, I can't get 3D Studio Max to do anything beyond rendering 
polygon meshes either, and yet it's ment to be "the most powerful 
modeller in the world"...)
