  1. Same here... I remember renting the original Top Gear from Blockbusters or Movie Gallery. I enjoyed it; definitely a memorable game, real fast pace and great music. I can't tell you how long I wished and wondered why both the 7800 and 5200 never really caught on... Both systems had way better hardware than the any of the game console that came afterwards; the NES, the Sega Master System. I think in the thick of the business aspect, Atari just kind of lost focus and tons of money due to the arcade crash of 84. To be quite honest when I compared SNES "Top Gear 3000" with 7800 "Motor Psycho" looking at how they both performed, personally I believe the Atari 5200 has a really get chance of pulling "Top Gear 3000" style graphics where with some clever programming, it might be possible to hit a sweet spot in performance... That was really where my head was when I begin looking at both games. I totally agree... The 7800 and the 2600 are more than deserving of extra hardware on the cartridge that really pushes the system and adds better ranges of graphics, sound and AI. I like the added music to the game; something that was very much needed on the 7800 in comparison to the 2600 sound chip. It sort of reminds me of "Gimmick and Batman Return of The Joker" for the NES by "Sunsoft". I think the cartridges for those games used extra ram and a sound chip that added more channels. I'd love to see more great games released for that system with better graphics and sound.
  2. Hi everyone... Today I was looking at some stuff on the SNES via the Internet and ran into this game called "Top Gear 3000"... It's a typical racing game, but the game engine is very fast due to a co-processor on the cartridge to draw the roads on the fly. When I looked at the game play, it reminded me of the Atari 7800 game "Motor Psycho" where you race these tracks and even find yourself flying in the air when you hit a ramp. I was thinking the 7800, although not as fast as the SNES with a co-processor, really does hold its own when comparing both games.
  3. Yea I use to compare the NES hardware with the 7800 later as I find out more info on the 7800 specs and wonder how Atari dropped the ball, but looking back, they just lost so much money they didn't really care too much for the gamer liked they should (IE WarnerBrothers) and saw a great product that could sell like slice bread considering how well the 2600 did. Even looking at the Atari 5200, which was basically the Atari 800 computer; even with the graphic chip the way it was, it still had way more leverage over the NES due to the amount of RAM the system was packing. Nintendo just had a better formula for making home games versus the shovel-ware the 2600 was getting... It was just so much hype, I guess because it was so much money in the air back in those days they just lost sight of things and let precious opportunities slip through their fingers. Didn't mean to rant on like that, but when I think of the "Atari System 1", I always think of the Atari 7800, which was out around the same year 1984... It was also the year I was in first grade remembering all of the Atari hype that was previously around before the NES debut so... lol 🤣 It's great memories for me as well.
  4. I was just watching some of the video and Atari really just built a great name for themselves back in the early 80s... It's too bad they never consolized the "Atari System 1"; at one time I use to think that the 7800 was Atari attempt to bring arcade games like Road Blaster and Indiana Jones to the household until I researched the history. I would love to home-brew for the Atari System 1 and did some search on the hardware, but it looks like some has already manage to pull off something on the old arcade hardware.
  5. It would've been cool if Atari added extra memory to the CD unit for the Jaguar... Also I was looking at the "Motorola 68881 FPU" and thought it a nice addition to the CD unit. If you look at the "Sega CD" it had added features like a faster 68000 with hardware to support scaling and rotating. Being that the Jags 68K and DSP are the only processors to have full access memory, every little resource would've helped. Is it possible to use the 68881 to control a CD unit...? Just a geek having fun with ideas, that's all. 😉
  6. Seems like a good idea... Even with the Jag as it currently stands I often thought about the back ports on the current Jag adding some memory through those ports... To my understanding I think the DSP would be the only processor to have such access to something like that. The GPU OP probably wouldn't allow any access to any extra memory from the back unless my understanding of the Jaguar is flawed. The GPU back port is meant to display images only via the video chip receiving images from the OP; haven't find any documents to dispute those facts, which is shame for the GPU not to have access to extra memory without a workaround that's taxing to the system.
  7. Man I can't wait to see this project come to fruition... Very nice. Every thought about replacing the Motorola 68000 with a 68020 or higher with internal FPU?
  8. Hi my name Philip, but you can call me ptw-ace or just ace... That was my user name in previous Atari Jaguar forums. I've been thinking about selling my Jag. I've had since 2004 and have had a lot of great moments with the system and the Jag community. If I was mention everything, I'd have to write a four page topic on my experiences with the Jag and the community once existed. What I can tell is that for years people wanted to see new games released for the Atari Jaguar system and put tremendous effort in to doing so from creating the infamous "Skunkboard" where you can plug it in the cartridge and program the Jag via USB... But before then there was the "BJL or Behind Jaggy Lines" where you physically had to remove the Jags bios chip and replace with the BJL software and then program it from a PC or an Atari ST or an Atari Falcon if you had one. Songbird productions, which is still selling games for the Jag has a game called "Protector"... This game has a limited version of BJL on it when you press the zero button; the game was released I guess around 03 or 04, it could've been earlier, but it was at the time when you could program the Jag via printer "printer port to Jag controller port". I myself, wasn't really a programmer and to this day, still don't know how to program like I should, but boy it's been quite the learning experience where if you stick around a thing long enough, you'll gain more understanding about a system then you had when you first started. Well... The Jaguar is infact a 64bit system because of the Blitter that was 64bit with a either 64bit bus or could produce 64bit output despite the other processors being 32bit (I always wind up going back to the tech manual for that info so don't take what I said too litterally, if you see anything wrong just correct me). Whatever the case the potential for the Jag to really be the next gen system of it's time was all there, but the Jag system design was riddled with bugs due to a poor system design. It was suppose to be a big shot 3D system, but the programmers, although could do 3D on it, would constantly run into problems and didn't really pin point the core causes of where the problem came from. The biggest problem that stuck out was the "Motorola 68000 processor" that would hog the systems BUS whenever it was in use... Latter the expert homebrew Jag programmers would conclude that the best way to take advantage of the system was to let the Motorola set the tone for the other chips to work and then cut it off, but being that the Atari community comprises of Atari ST enthusiast; a computer that also uses the 68000, would often beg to differ. Me personally thought it would be a waist of a chip to not use it for something, but I also believe that turning the chip off and using the other processors is probably right on point. For me I wanted to do a game for the Jag for sometime now, but real life demands required more of my attention then the Jag, which was the case for most people who wanted to make homebrew games for the Jaguar. My thing was the 2.5D games like "DOOM and Phase Zero"; no so much the game, but the pesudo 3D engine behind the game... The reason I believe most of Atari 3D games lagged so badly was because everyone was using the Motorola 68000 to handle game logic not truley realizing that the chip was actually slowing the system down; that's why games like Checkard Flag, Cybermorph, Missle Command 3D, and even some 2.5D games like AVP and "White Men Can't Jump" ran very slow because the main plan was understood to use the 68000 for game logic and let the other chips do all the 3D work; that's the way Atari sold it. The M68K was put in there to give people a quote "Warm and fuzzy feeling"... It did anything but that in the end, however it didn't stop the ambitious from trying after Hasbro released the system to the public in the mid 90s. They say when one doesn't learn from history, one is doomed to repeat it so it's always a good idea to tell your story even though I might be comming off a little strong in a new forum like this. It's always good to hear another side of the spectrum and as you can probably guess from the rambling, I could go on and on about the many adventures in "Jaggy Land" as in BJL, behind JAGGY lines, get it... I've been thinking about selling my Jag collection and have already sold a few games on ebay; I even have the infamous first and second generation "Skunkboards". For what it's worth I've enjoyed the Jag for many years now and I've learned more about computers fooling with the Jaguar reading the tech manuals other tools Atari release to the programmers of the day. The Jag system (The Big Cat) can be quite a system to tame if you'r just starting out and does require prior programming knowledge. They say it's best to just start simply by learning C programming language, but you WILL have to know how to program in Assembler because the C tools Atari released to the programmers is in efficient unless you're using the 68000. The Jag GPU doesn't have access to the main RAM unless you create a work around, which does exist out there, but for C programming, you'll only have internal cache memory in the GPU and the DSP (sound chip) due to an unresolved hardware issue. I know the message I'm giving is a little generalized, but they are very much key to having some level of success programming that system; the Jaguar was really rushed out the door too soon in an effort to capture the market of it's time, but if Atari had put more time and effort in to the system and released it around 95 when the PS1 was released, it would've out performed Playstation and Saturn becuase of the 64bit blitter the Jag contained and the other processors as well. The game "Tempest 2000" is a wonderful example what the blitter was capable of using the GPU for the 3D and the Blitter for all of the special effects. If the 68000 chip had it's internal memory like the other processors did, they would have given the programmers some head way to make up for any lost effeciency because the Atari Jaguar data bus is a bottleneck with all five processors sitting on top of it with the GPU having no access to main RAM without a work around. Some suggest the 68020 would've been a bit more expensive, but more appropriate because it having it's on intern memory in it. But as you can see, I can go on and on, but it just shows the nature of the Atari Jaguar internal workings and I still didn't cover it all, but I hope this little information will be helpful in some way to someone.
