with BIOS works fine thanks

unfortunately doesn't work in BigPEmu 1.052. Does it need GameDrive or emulator is not ok?

wow 308 pages. @Trabucco many thanks. I would read more about two topics: Atari 7800 vs Jaguar and Atari Blossom video card vs Jaguar. The first one - 7800's Display List (which is completely different from XL' Display List) is similar to Jaguar's Object Processor List (very similar structure and instructions). I wonder if Object Processor one was inspired by 7800. The second one - there was a rumor that Jaguar shares some technology with Richard Miller's Atari Blossom video card (both have a fast memory bus and the blitter). According to that post https://www.atari-forum.com/viewtopic.php?p=222157 "All three of them were from Sinclair: Richard Miller, Martin Brennan and John Mathieson. Richard Miller called Martin Brennan and John Mathieson since he got task at Atari to make 2D console (based on his experience with Blossom)."

my first programming attempt was Basic on 800XL wit 1050 (both not mine unfortunately) in 1984 or 86. I remember that program well, it was in GR.8, drawto bunch of lines from a middle of the screen to the top, right, bottom and left border.

actually, Jag can show thousands or more polygons... but not in one frame

looks really cool, but the sound is a bit strange (small speaker?) I wonder about details? is it the only lynx or is he going to produce more?

that is not mine, @AnimaInCorpore ca you help @Stephen ?

that one is great

cool regarding pattern38, I see a moire on yt video and I wonder if was it captured from a real TV.

I second that idea. Would be cool to have it on the Jag

I wonder whether would be possible to use cart ROM bank swapping, as it is done in case of Atari XL and Atari 7800 cartridges

@laoo does it mean that we can expect a new Felix version?

ok, but I see that it has following pins: D0-D31 and A2-A22 plus OE0/OE1 and WE0/WE1

interesting I see it that 'Butch' has 32bit data bus and 22bit address bus, it means it has an access to the whole (4MB) Jaguar's ram. Does it have DMA chanel?

there were a lot of great plans, unfortunately lack of money... regarding Amiga fans hijacking this thread, I'm pure Atari fan. C64, Amstrad,Amiga or Spectrum are quite nice piece hardware but they are out of my scope

true, the timeline is not clear. anyway, more than about amiga I would read about other companies visited by Tramiel when he was looking for a new technology for the RBP (like mentioned The Mindset) It's a shame that "Business is war" book didn't come up: https://www.pinterest.es/pin/185773553354331915/

Another interesting quote, which is aligned with https://mcurrent.name/atarihistory/tramel_technology.html: "By late July, Tramiel fired nearly everyone involved in the 8-bit product lines to focus on the RBP. Commodore’s injunction slowed down RBP development. He needed leverage against Commodore. Jack's son Leonard Tramiel found the $500,000 cheque from Amiga along with the loan agrement and showed it to his father." https://thedorkweb.substack.com/p/crash-and-burn-the-amiga-st-story

"1984 August 13: Atari filed a suit for fraud against Amiga Corporation in Santa Clara, Calif., Superior Court. According to Leonard Schreiber, Atari's general counsel, Amiga signed an agreement in March 1984 to develop three microchips for Atari, Inc. Atari, Inc. then advanced the company $500,000. In late June, days before Mr. Tramiel and fellow investors bought the Atari unit from Warner Communications, Amiga canceled the deal and returned the money, saying that the chips did not work. (NYT) " https://mcurrent.name/atarihistory/tramel_technology.html

that is a bit amiga centric point of view. Tramiel wasn't interested in Lorraine but in a new technology. Before joining Atari Tramiel had a plan to buy a new ready to use technology, we know he was interested in buying the Mindset (exAtari engineers computer with the blitter) also Lorraine chipsets was taken into account. The timeline was a bit different. Amiga repaid the loan to Atari one day earlier than Tramiel bought 51% of Atari. Till that day Tramiel wasn't aware (fortunately for us because ST is so great as it is) about that loan. Tramiel surpassed both those machines in areas (plus faster CPU) mentioned earlier by me. I understand that for gamers those features are useless, but ST wasn't projected as a gaming machine, but as a computer for a power users. And these features are 'killer' in this area.

in many aspects. In 1985 Atari had following features: - 31Khz VGA high resolution video mode (plus great paper-white monitor). Here Atari was 5 years ahead. In 1985 Amiga had only low res 15Khz mode, and only got this 31KHz mode in 1990 with ECS chips. - Huge 4MB RAM (available for Video/Audio/HDD DMA). Amiga never reached that limit. In OCS Amiga it was 512KB chipram, in ECS it was 1MB and later 2MB. - Fast external DMA channel port for HDD, Laser Printers, Scanners, networks etc. Atari was 4 years ahead. Amiga got this but only as an external device A590 in 1989. (IDE in A600/A1200 has no DMA!) - Boot from HDD. Atari was 3 years ahead. Amiga till Kickstart 1.3 didn't support boot from hdd. And more like much better price, built-in power supply, built-in MIDI ports, built-in (no need floppy with the desktop) ultra stable and efficient GUI OS, native MS-DOS floppy disk format, and so on

800XL Mini would be cool. I would buy it.

ok I see it now, you are more Miner fan than Atari fan, and this is ok with me. I'm focused on Atari (and hardware released by them), regardless of who run it - Bushnell (the Boss), Warner, Tramiel or Infogrames. Non-Atari projects of former Atari engineers (like the Nuon, Sharp PC-3000, Mindset, Commodore Amiga and tons other projects) are interesting but out of my scope. So I find this discussion pointless. Anyway this is a thread about Atari VCS ( yep, Atari hardware ) lets keep it clean.

read the Wiki first: "Jay Miner focused on making an ASIC for the display adapter. Early on, the ASIC display adapter was named the Television Interface Adapter (TIA)." - making asic doesn't mean he designed TIA chip, because someone else did it before: "Using a breadboard prototype for the display adapter atop a 6502 testbed system, Milner was able to demonstrate the ability to program a simple version of their Tank game". Below you can find Atari 400/800 designers list: Steven T. Mayer - early system design, overall plan Douglas G. Neubauer - POKEY logic design George McLeod - CTIA/GTIA logic design Ronald E. Milner - early system design Francois Michel - ANTIC design Mark Shieu - POKEY chip design Steve Stone - POKEY layout design Steve Smith - Technician for ANTIC and GTIA Delwin Pearson - Technician for POKEY Kevin McKinsey - 400/800 case design Joseph C. Decuir - ANTIC logic desgin, early system design, overall plan Jay G. Miner - System architect, VLSI manager, overall plan Regarding updating the Wikipedia, Miner never was the real Atari, it was just Atari's employee who joined the real Atari for a moment. But feel free and update the Wikipedia with your version of history:

never heard of it before. I've just checked it and G.I is a nice sound fx editor, plus C and Pascal example usage

I appreciate Miner work (and also other great Atari engineers like Shivaz/GCC team/Brennan/Mathieson/Mical/Needle etc), but A8 is only part of Atari portfolio (e.g. best Atari 8bit machine - A7800 was designed by someone else - GCC) . He was just an Atari employee, and for a while. For me the real Atari is the boss Bushnell (and maybe later Tramiel) And actually TIA - the heart of A2600 was designed by Steve Mayer and Ron Milner not by Miner. His (and other mentioned earlier engineers) work done for other companies is not part of Atari's history.
