Autor: Robert Schaffner Robert Schaffner Am Schäferpfad 10 63303 Dreieich EMail: Robert Schaffner @ OF2 (MausNet) Tel/Fax: 06103/67197 Wen stört er nicht, der laute ungeregelte Ventilator in Ataris neustem Abkömmling, dem FALCON F030. Es gibt Dinge über die man ziemlich ausführlich diskutieren kann, und es gibt welche, bei denen man erst überhaupt nicht anzufangen braucht, hierzu zählt eigentlich eben auch dieser Ventilator. Weder der Typ des eingebauten Lüfters, noch das Kaufdatum des F030 spielen hierbei eine besondere Rolle - das Gerät ist einfach laut. Da ich noch die letzten warmen Monate des letzten Jahres abgewartet habe, u...

Diese Textdatei kann im allgemeinen nicht auf jeden F030 angewendet werden. Zumal es schon alleine nur im Soundsubsystemeingang schon zwei verschiedene Sound_In Beschaltungen und auch zwei verschiedene Schaltpläne gibt. In jeden Fall sollte man bei Knack- und Kratzgeräuschen währen dem Sampeln, dem Abspielen einer CD ect. zuerst sein ...

Well, so it happend, ct60 arrived to our hands =) Short time after receiving my CT60 I've got some nice c2p source from Evil/DHS by Michael Kalms aka Scout/Appendix where I learned some things about 060 so why not write it here:) Burst mode I was very surprised when I didn't find 'burst mode' bit in CACR register. But this doesn't mean 060 has no burst... 060 operates in burst mode all the time :) And what is this burst mode? If you read my article about 030 timing you know how it works in the 030 cache: every word or long read has its place in data cache (unless the data cache isn't disabled and/or fro...

I tell you the truth - I'm always reading about how slow ST RAM is and that Fast RAM is something unbeatable etc, but I never knew WHY. There is only one Falcon timing document - the one published by Rodolphe Czuba with CT2. But in my eyes, this doc is so short/unclear and SHITTILY translated, there's no way to get the idea for non-hw freaks like me. But one nice day I told myself: "It can't be so hard... other ppl understood that, I can too" :-) So I downloaded both uk and fr version of the mentioned doc and started to read... OK, after some weeks :) I've got that damned idea... I have to say I haven't got any osc...

by TimJ/Vertigo "I am he, as you are he, as you are me, and we are all together" email: tim@legend.co.uk irc: #coders #vertcode revision history: 16/02/97 v1.0 - Initial version INTRODUCTION First off, I hope this doc is of use to some people, and maybe other people will find it interesting. Recently, I've been thinking a lot about phong shading and lighting. There was something that was bugging me. I couldn't quite put my finger on it. It was something I knew to be true, but I had to explain it to myself. It all started when I was chatting to Vector about true phong shading. We'd both recently looked at Voltaire&#...

Just before Christmas, I rented two Sega Saturn games, Virtua Racing and Sega Rally Championship, in order to compare the two. Santa was only going to bring me one, so I had to choose: VR was my favorite in the arcades for a very long time, and I had heard just wonderful things about Rally. So I sat down and played both for few hours each, on separate occasions. I fell in love with Rally, but did not much care for the translation of VR -- it was missing the arcade feel. (though, since Santa also brought me an Arcade Racer steering wheel accessory, I happen to really like VR -- perhaps as much as Rally. The steering wheel makes all the dif...

by TheGlide/SpinningKids Milan, Italy - June 1 st , 1998 INTRODUCTION I assume here you know the basics of texture mapping, as explained in fatmap and fatmap2 docs by MRI/Doomsday. This doc is about texture mapping using texture maps stored as tiles, namely 8x8 pixels tiles. Storing the maps this way can improve very much cache access. Most of the time we have to traverse the texture through non-horizontal lines, and this causes many cache misses. The worst situation happens when we have to traverse the texture vertically: each texel we access will be on a different row, and this will require, from the processor side, a whole cach...

The information contained in document will allow you to realistically simulate jumping and interstellar maneuvers. The purpose of this document is to understand the physics of the world we live in, and apply realistic physics to your game. It will not give you optimized routines for your program, that is your job! But if you understand how things work, it will be a heck of a lot easier. Basics There are some key terms I will define to make sure we are talking about the same things: Distance : Total path of travel. Displacement : Difference between original position, and final position Speed : Change in displacement divided by the change i...
