-
- Crystal Dream is a result of many hours spoiling the schoolwork and other
- necessary dutys, sleepless nights, lots of fun developing, lots of hard work
- and a hell lot of debugging and finetuning. (mera kŷd - mera buggar)
- We planned to contribute with it at Hackerence 5 in H☓rn“sand, but we ran
- out of time and couldn't show a 100% version. Some time passed till we got
- all the inspiration needed to finnish the project, but 6 weeks later the
- product was ready for a release.
-
-
- REQUIREMENTS
-
- This demo requires a 12 MHz 286 with VGA graphics, but we recommend at least
- a fast 386 computer. You'll need about 550 kb free memory. If you have a
- 386 or 486, make sure that there's no EMM386/QEMM386 driver or something
- like that installed, because these programs slow down your computer while
- playing music.
-
- It supports SoundBlaster, SoundBlaster Pro (Stereo), parallell port D/A
- converter (Mono and Stereo) and internal speaker for the music. If you don't
- have a SoundBlaster card, we recommend you to build a D/A converter. The
- internal speaker has VERY poor sound quality.
-
- Howewer, you should be entertained by this demo when it is running on a true
- 486 computer with a real stereo D/A converter or a SoundBlaster Pro card
- connected, in a dark room with a cold cc in your left hand (Why left?
- [because it's red of course!]) and your bottom pressed into your most
- comfortable chair. We hope it will amuse you even though it's only 16 colors
- at the screen, but sometimes that might be an advantage.

- HISTORY
-
- The group "Triton" was formed from the old group "The Physical Crew" in
- winter 91-92. The most succesful cooperation between TPC and Vogue was
- soon developing into a demo, and for this purpose, the name was changed.
- Some of the earlier TPC releases are "PC Demo" and "Vectra", but those
- demos were no products of some serious work. Vogue is originally an Amiga
- programmer and was a member of Phenomena in 91. The name "Triton" is taken
- from a moon of Neptune.

- Some basic rules:
-
- - If you want to contact us - USE OUR REAL NAMES!!!
- - We do NOT want to swap software.
- - We won't join any groups with only some gfx-artists and musicians.
- - We won't join any other group either.
- - If you're a coder, you're very welcome to contact us. (Not LOOT)
- - Contact us if you want to inform us about any party beeing held somewere.
- - Contact us if you want to spread your latest demo.
-
-
- THE RAYTRACING STUFF
-
- If you're into raytracing and other vectormatematicaly based graphic
- producing, you should contact Vogue. The raytraced pictures were rendered
- in "Synthetic Image", which is my own raytracingscene editor. It was coded
- as my examswork in the last degree of the gymnasium. (Natur sŷ klart!)
-
-
- TECHNICAL INFO ABOUT THE MUSIC
-
- If you want to contact us about the music system, you should ask Mr. H,
- he's the one behind the music software and hardware. (Teknisk linje, vad
- annars???)
-
- The music routine is very optimized since the last demo (Vectra). It can now
- play at 38 kHz on a 12 Mhz 286. As a result, it might sound a little poorer
- at lower frequences.
-
- The SoundBlaster routine uses DMA and takes less CPU time than the normal
- way. It is also possibe to use Stereo on a Pro card. Thanks to Shadow man in
- TCB for GREAT help with this.
-
- You can now play Stereo on a D/A converter in the parallell port. This
- requires an improved D/A converter with a REAL D/A, it won't work with
- resistors.
-
- If you still want to build a simple resistor D/A, here is a drawing:

-
- The real D/A converter with stereo is a bit more complicated, but here is a
- drawing. You can find the components in for example ELFA. It should work
- (it does for me), but don't blame me if you burn your parallell port...

- The pins in the parallell port is used as follows:
-
- 1 - Selects left or right channel
- 2 to 9 - 8 data bits (2 = Least Significant Bit , 9 = Most ...)
- 14 - Pin 1 inverted (isn't used in my D/A, but may be useful)
- 25 - Ground
