| mntmn | _Bnu: raspatari! | 12:38 |
| _Bnu | AtariStorm... | 12:40 |
| _Bnu | I'm stuck with what seems to be some bus timing issues at the moment, though. | 12:41 |
| _Bnu | I can read and run the ROM code for a bit, and then I suddenly can't... | 12:41 |
| emiespo[m] | Gee RaspAri ;-) could overshadow the Amiga project… I bet it would perform even better there (thinking of the issues accessing chip ram… and the fact that the Atari ST is by nature simpler and has a faster video access). | 12:48 |
| _Bnu | I mean, I doubt it... | 12:49 |
| _Bnu | The Atari ST coders all seem either bad or dead. | 12:49 |
| _Bnu | Otherwise I wouldn't be the one figuring out why this wasn't working to begin with, lol. | 12:49 |
| _Bnu | Also 9-bit RGB... | 12:50 |
| _Bnu | You can choose between bad colors and bad colors. | 12:50 |
| _Bnu | And monochrome, I guess. | 12:51 |
| emiespo[m] | Yes it takes good coders to get results, and indeed I remember a demo from one of the greatest (Chaos of Sanity) where one effect was much faster on the ST than the Amiga - there was a complex explanation of the reason behind this, I remember something about a faster memory access and the bitplane format. Not just the extra MHZ. :-) | 13:01 |
| mntmn | but ST has midi and cubase right ;) | 14:03 |
| mntmn | i have an ST | 14:03 |
| mntmn | but it has some illness, it switches off after a few minutes | 14:03 |
| mntmn | one day i might repair it | 14:03 |
| Jope | I sold all my ataris.. sometimes I regret selling the falcon tho :_/ | 14:04 |
| emiespo[m] | I think my A4K has a problem with the CPU bus connector. I finally identified it: at some point it stops booting (would start loading the startup but then gets stuck), and putting some pressure on the board fixes it | 14:41 |
| mntmn | Jope: ouch @ falcon | 14:54 |
| mntmn | emiespo[m]: i have the same theory about mine... maybe they just wear down? | 14:54 |
| emiespo[m] | <mntmn "emiespo: i have the same theory "> It’s possible, besides, I sent mine for recap and when it came back the cpu card was floating around 😭 so it’s possible some soldering pin got loose or damaged in the process. I’m scared enough to disassemble everything even to just take a look at it… ideally the whole board ought to be replaced (moving chips), which is another thing that I can only pay someone else to get done! | 15:13 |
| emiespo[m] | In short: I believe this is the main reason why the new Re-XXXX Amiga motherboards exist | 15:13 |
| mntmn | makes sense | 15:15 |

| Claude | the Atari might have a little faster CPU in MHz (8MHz) but is slower than a Amiga with 7.093MHz . because an Amiga interleaves bus access with the chipram , maintaining in most cases a 0 waitstate bus access. where as the Atari does bus arbitration handshakes | 17:15 |
| emiespo[m] | So it’s generally slower? Then I guess a “really good coder” is what we saw with a game like Vroom :-) | 18:11 |
| apolkosnik[m] | It's a neat trick on the Amiga that's utilized, because every other cycle is used by the custom chips, when the 68000 is executing the instruction (not reading nor writing) | 18:25 |
| emiespo[m] | <apolkosnik[m] "It's a neat trick on the Amiga t"> Yeah I know that. I read somewhere that the ST, not having to share bandwidth with the Copper/Blitter/Sprites and whatnot would give more useful WRITE cycles to the 68000. I wasn’t talking about code execution, but video memory access. Indeed FAST-RAM on the 500, despite its name, doesn’t make a huge difference (I’d say it becomes still a 33% faster). | 18:43 |
| _Bnu | Well, Fast RAM speed depends a lot on the path from the CPU to the memory. | 19:19 |
| _Bnu | Motherboard Fast, Z3 Fast, etc., those naturally aren't a super lot faster than Chip, though they don't have to compete with the chipset for that. | 19:20 |
