Wrong, the topic's context is from the 1st post Read https://eab.abime.net/showpost.php?p...24&postcount=1
A1200 criticism vs the world e.g. SNES example. Selected SNES games used the platform vendor's math co-processor accelerators which is the same argument made by Commodore UK's MD. ------------------------------------------ Gilbert's 1st post: Was anyone else disappointed with the A1200? Most Amiga users and magazines seemed to be very happy with the A1200 when it came out. I wasn't at all, and a look at the first games pretty much ended my association with Amiga gaming. I just saw the same games with more colours and a bit smoother. There was no wow factor. After that I stuck with the Amiga 500 (with half meg memory expansion) and my Super Famicom (Jap SNES). Here's what Commodore got wrong in my opinion 1. Too much focus on creating higher-res screen modes with more colours (and also making the blitter work in these different screen modes) and not enough on enhancing gaming(8 or maybe 16 sprites when the comparitively old Megadrive and SNES could manage 64 and 128 respectively). It's a bit like the original Amiga - yes it can display 4096 colours on screen, but the majority of the games for the system were 16 colours (Albeit some had added some Copper magic) and most didn't even run at 50/60 fps. That was fine back in 1985 but 7 years(!) later you expect a significant upgrade. 2. There was a mild improvement to dual playfield mode. Great!... when the SNES had 5(?) playfields and could scale and rotate whole screens. Commodore seemed to have no sense they were competing here.... 2. Sound chip needed 6 channels to get a decent track playing with sound effects. Again SNES and Megadrive have 6 channels each. Using the same sound chip from 1985 was ridiculous! 3. Like the original Amiga, if you wanted to get a good number of objects on screen with a lot of colours and scrolling, you had to spend ages using hardware tricks or specific techniques. Time = money and developers aren't going to want to spend 2 years making an arcade quality game on the A1200 when simpler systems exist.... I do have a CD32 now, but it's not very impressive from a technical point of view, even the mighty Banshee is bettered on both the SNES and Megadrive. The reason I like it is because it offers something a bit different and it's an Amiga It's fairly obvious it had no hope of competing long term. I just find it hard to see what Commodore was thinking with the AGA architecture?? Last edited by hammer; 17 April 2024 at 06:47. |

Nope.
https://www.os2museum.com/wp/the-851...s-accelerator/ " Microsoft and IBM also shipped sample 8514/A drivers in their various DDKs for Windows and OS/2; these were often used as a basis for developing accelerated drivers for other boards." https://minuszerodegrees.net/video/I...%20187-054.txt From 1987 (document taken from http://www-01.ibm.com) IBM offered documented publication for the following items: 1. Display Adapter 8514/A Adapter Interface Application Developer's Tutorial (S68X-2279). 2. IBM Personal System/2 Display Adapter 8514A Technical Reference Manual (S68X-2251). You simply spreading misinformation! Quote:

From https://www.landley.net/history/mirr...re/haynie.html 1. Dave Haynie: He and Ali also decided that AA wasn't going to work, so they canceled both AA projects (Amiga 3000+ and Amiga 1000+, either one better for the market than the A4000 was), and put it all on the backburner, intentionally blowing the schedule by six+ months. ------ Where's your counter-evidence to debunk Dave Haynie's "put it all on the back burner, intentionally blowing the schedule by six+ months" claims? ------ 2. Dave Haynie: They canceled the A500, which was the only actively selling product ever canceled in C= history, to my knowledge, and replaced it with the A600. The A600 was originally the A300, George Robbins's idea of a cheaper-than-A500 Amiga; a new line, not a replacement. Sydnes added so much bloat, the A600 was $50 more than the A500, $100 over the goal price. --- The information from David Pleasance's "Commodore the Inside Story, The Untold Tale of a Computer Giant", Commodore Germany pushed for a hard drive capable A300 model which caused other problems e.g. A600's sales flop and A500's cancellation. A500's cancellation caused Commodore's 1992 revenue to tank. 3. Dave Haynie: Now, this is ready to go in April. You have to understand Commodore's working to know what happened here, but basically, C= was run like a cellular company. Each cell did it's thing, and ran fairly independently of the parent (CIL, Commodore International Limited). This is why every company did marketing differently; different independent marketing companies. So now, to get their product, each marketing company places orders, and C= fills them as best as they can. But guess what absolutely no one ordered. If you said the "A1000jr" (real name as Amiga 2400 or something like that), you win the LBM Effigy, to be burned later. Nope, no one wanted a stripped-down A3000 without AA graphics (or SCSI, or flickerfixer, or Zorro III, etc). So now Sydnes is in a panic. So he calls on Greg again to start up the next thing, the A4000. Fast. This command came in May, they wanted to ship in September. So Greg takes the A2400 design, drops in the AA stuff from my A3000+ design, gets me in to fix it to run Zorro III, etc. Sydnes mandates IDE (ATA-1, I think is all you get), so that's done, poorly, with a PAL (you couldn't do good ATA in a cheap programmable part back then; you can today), so goodbye SCSI. Anyway, no joy, but there's an A4000. --------- AGA's introduction was delayed by "more than 6 months". There was an Amiga chipset R&D disruption after the original Los Gatos Amiga team was dismantled in 1987. The R&D 2 MB Chip RAM ECS capable design occurred before the A500 Rev 6A's 1989 and A3000's 1990 releases. "No new chips" directive was applied for A3000's R&D phase. Meanwhile, PC VGA cloners started to release their 256 color display capable VGA clones around late 1987 e.g. ET3000. http://ftp.bambi-amiga.co.uk/amigahi...ggebrecht.html Question: Tell me about AAA - it's been worked on since 1989? Lew Eggebrecht: "Yes, we worked on it from an architectural point of view for a long time but it's only been serious for about a year. It was obvious that AAA was not going to meet our cost targets for the mid to low end systems. We wanted to continue that development and we also had to have an enhancement quickly so, AA was the solution to that problem. It would have been nice to have AAA at the same time as AA but we just couldn't get there." ---- 1 year of serious AAA R&D wouldn't be enough time. Developing 256 colors display chipset in 1989 was late when competitors like ET4000AX were released in 1989. Commodore's R&D committed to two 256-color display chipsets i.e. C65 and AGA. Quote:
Commodore PC30-III has a 16-bit AT-IDE interface on the motherboard and it was reviewed by Australia's Your Computer Jan 1990 issue on page 108. It wasn't a good policy to tank the year 1992 revenue with an A600 sales flop and cancel the best-selling A500. Quote:
AGA + Budgie is required for the A500-type model without Gayle's IDE and PCMCIA. Gayle replaced Gary in the A600 and A1200. TF1260's fast IDE used an XC95288XL-10TQG144C AMD-Xilinx CPLD chip. Quote:
The CD-ROM interface is a crippled SCSI-I connector Quote:
The timeline for 16-bit IDE. Fall 1984 – Bill Frank of WD develops the initial IDE concept and it is shown to IBM, DEC, and Compaq that winter and spring [1] May 1985 - Compaq Deskpro 286 announced, apparently containing a conventional AT controller and ST506 drive. July 1985 - WD IDE business plan includes a “40 pin, single cable connection for IBM PC compatible card” and states that WD “is negotiating a custom project with Compaq Computer. The product will be a 20 megabyte Integrated Drive possibly using either a Microscience or a Tandon head/disk controller.” February 1986 - Compaq Portable II announced, containing an IDE drive comprising a WD IDE controller mounted on a 3½-inch drive by from MiniScribe September-October 1986 - Ken Hallam of WD presented a paper on IDE at Buscon East. Late 1986 - Compaq Deskpro 386 ships, containing an IDE drive comprising a WD controller and a 5¼-inch CDC drive. February 1987 - Compaq Portable III announced, containing the Conner 40MB 3.5” CP341 IDE drive. June 1987 - Conner announces the CP342 IDE drive as an OEM product April 1989 - CAM Committee releases first draft of the ATA and EATA specifications. Late 1989 – Compaq announces SystemPro PC server, using IDE drives in a RAID configuration. Quote:

Don't forget that Amiga is an actual Home computer, and not only a game console...

Unless you provide those documents then i'm right and you are wrong - check what is inside IBM document titled exactly same as yours for 8514 but about XGA: http://bitsavers.trailing-edge.com/p...ence_Sep90.pdf No registers there! And other document (also seem to be unobtainum) covers AI i.e. software interface but no registers... So unless you provide IBM document covering internal 8514 registers then you are providing nothing but misinformation - obviously you are not checking sources, instead purely relying on some random information's provided by google... We are aware how to use google... Quote:
Now technical part to show how you manipulate with data. IBM card is MCA so automatically market for this product is limited, then it has IBM quality (way superior) vs Asia clones and seem overall design is cleaner and probably faster than ET3000 but anyway this is completely unrelated to main topic so please stop flooding thread with random pieces about PC and TSENG. Quote:
Already proved at least two times that you have no clue about yet you claiming things without justification, this was on e of your claims about ET4000 being compatible with 8514 (despite ET4000 having no hardware acceleration, not even hardware cursor) - any SVGA card can be 8514 compliant if you provide 8514AI driver but this not make it 8514 - native implementation of graphic functions will be probably faster than trying to implement 8514AI.

If there is no sane limit then why we not discussing A1200 vs SGI or Cray? Topic is on people disappointment about A1200 but not about superiority of ET4000W32p over ATI Mach32 or some TIGA boards. Btw e.g. from my perspective is exampli gratia but it has exactly same meaning example given. |

Worse - GTA was never released on Amiga! GTA 1 shall be released on Amiga somewhere around 1992! Shame on Mahdi Ali, Irving Gould and DMA design! ![]() |

I remember, playing a lot Mortal Kombat 2 on my friends Amiga 500, 1MB
Sure, it was a bit tedious swapping disks, and waiting like 30-40 seconds between rounds (but not as terrible as many claim). But when the round started, it was a joy. Very smooth animation, awesome gameplay feel, fantastic sound, all in all AAA title, and AAA conversion. I had no issues playing on joystick with one button, and could execute very quickly pretty much any move I wanted. After maybe a year later, I tried it on my other friend 386DX 40Mhz, 4MB Ram (minimum to run), with colored 14'' monitor. First of all - the huge like house ugly sharp pixels, as opposed to nice CRT TV smooth look. Second, the frame rate was totally inconsistent. It goes from fast to slow, and opposite. which really affects (in worst way) the gameplay aspect. Third, you can forget about 2 player mode (unless if you had expensive joysticks for PC's), because if both players are on keyboard, each of them needs to use 9 buttons for the game, and keyboard doesn't accept more then 3 buttons pressed simultaneously. I can't even remember if my friend had Sound Blaster, or PC speaker. Last edited by d4rk3lf; 17 April 2024 at 19:22. |

Amiga mortal kombat was missing background animations only. Rest was spot on. I think they could do arcade perfect on A1200 but then could sell significantly less, due to user base number etc.

For DOS gaming, 386DX-33 or 386DX-40 PC needs to be paired with something like fast ET4000AX. For PC's DOS Mortal Kombat 2's minimum 386DX/40 Mhz 4 megabytes of ram (8MB recommended) 10 megabytes of free space https://www.neoseeker.com/mortal-kombat-ii/ |

[ Show youtube player ] Simultaneous Colors of Mortal Kombat (Sega Genesis vs Arcade vs SNES) Color Comparison Sega Genesis reaches 50 colors. 39 to 50 color gameplay range. SNES reaches 139 colors. 104 to 139 gameplay range. Reusing SNES's colors artwork, AGA's 128 colors (7 bitplanes), and ganged 64-bit wide sprites (16 colors) for the background would have done the job. Fast RAM would help. "8 bitplanes" is pushing the limits on the stock A1200, and it's already troublesome for "8 bitplanes" Turrican 2 AGA. Delivering a Mortal Kombat 2 like the Mega Drive version is not ideal since Mega Drive's "16-bit" experience mocks Commodore's "32-bit" marketing. Mega Drive has a discrete 16-bit system and 8-bit video (fast VRAM) memory split, unlike Amiga OCS's shared 16-bit Chip RAM (DRAM). SNES has discrete 8-bit system memory and 8-bit fast VRAM. Both game consoles targeted fast low resolution with 64 KB of fast VRAM. For CPU: A1200/CD32 with Fast RAM and 68EC020 @ 28 Mhz is about 8X compared to the stock A500. A1200/CD32 with Fast RAM and 68EC020 @ 25 Mhz is about 7.1X compared to the stock A500. A1200/CD32 with Fast RAM is about 2X compared to the stock A1200. A1200/CD32 with Fast RAM is about 4X compared to the stock A500. With Fast RAM, there's a less shared bus issue and it improves AGA. Last edited by hammer; 18 April 2024 at 03:57. |
