_BnuAh, your new video stuff doesn't have any of the things I added for the panning, so it's probably not going to work with panning, no. I'll try to rework it.14:58
_BnuI also need to change the driver back to some chip/palette type other than the ZZ9000, so it actually works on old Picasso96 again.14:59
_BnuI think I'll just start over with the panning, everything kind of messed up now, lolb.15:01
_BnuYeah, somehow the RTG panning commit to drivers got orphaned or something15:03
_BnuSo I'll just make a new one.15:03
mntmnoh shit, sorry for that15:09
mntmnalso thanks for the chip type hint, i again forgot about this15:09
Jopedare I make a small scandoubler vertical refresh request15:17
Jopemust send bribes to sweden..15:17
mntmnhaha15:27
_BnuJust sell me a recapped A4000 power supply that'll last for a few more decades and I'll consider it . . .15:27
mntmnbtw how did that atx adapter turn out?15:33
_BnuI mean, it's here, and it works... but I don't like it, lol.15:44

_Bnulol15:55
_BnuThe grayscale "powerup" doesn't even work in the AGA version of James Pond 2.15:55
pasikasus powered amiga15:57
pasiknever seen one before!15:57
mntmn_Bnu: i see! a4000 kinda back in business??16:14
mntmnthinking if i should order another buddha from jens16:14
mntmnor write some autoboot code16:14
_BnuIsn't the Buddha kind of crap compared to the FastATA...16:20
_BnuLike, Z2 only or something. Not that you're super likely to get the up to 16MB/sec from the FastATA.16:20
_BnuOn the other hand, the Buddha works on everything.16:22
_BnuBut why would you be running a Z2 system using anything but a PiStorm anyway... got PiSCSI there...16:23
mntmnno i mean for the 400016:30
mntmnsorry i mean for the 300016:30
mntmnthe 4000 doesn't even work16:30
mntmnalso i'm not really concerned about the speed, as long as it's stable and i don't have to wait forever... ;316:30
_BnuAh yeah, not sure if the FastATA 4000 works in the A3000 or not.16:32
_BnuBut it's the least annoying thing I've used.16:32
_BnuOkay, rebuilt my firmware and Rectfill Pattern and Text/Con-output are back to normal again...16:33
_BnuI must've disabled them for some reason at some point.16:33
_BnuOr maybe I added a crapton of debug output...16:34
_Bnumntmn, why is the ZZ9000 slower at WriteChunkyPixels than the PiStorm... can you fix Zorro III and make it 150MB/sec bandwidth...16:36
_Bnuhttps://media.discordapp.net/attachments/836238000148578324/869949642010427442/unknown.png You can tell that I didn't add any cheat codes to RectfFill Pattern, haha.16:39
_Bnuhttps://cdn.discordapp.com/attachments/789807768554831902/870315187587129384/unknown.png And a fresh set of my good old cheat scores from my magical 50MHz 68060.16:42
mntmncrapton 300016:47
mntmnwe can just move musashi onto the zz core 216:48
mntmnthen your bandwidth problem is gone...16:48
mntmnwe can construct a mini draco in there16:49
_BnuYeah, except then it's there for the entire rest of the Amiga instead, haha.16:49
mntmnwell, who needs those old amiga chips anyway16:49
_BnuTrue, true.16:49
_BnuI mean, I would love to replace the Buster with something that doesn't get in the way of every expansion plan anyone ever has for the A3000/A4000...16:50
_BnuA4000 is happy at 1920x1080 again.16:52
mntmncool16:52
_BnuNo intermittent video cutouts, no weird HDD shutdown problems.16:52
mntmnthat is nice16:52
_BnuP96 3.01 is still fucking with my palette, but that's my fault for not updating it yet.16:53
mntmnfuxxorz16:57
_BnuAlso, I must've indirectly sold quite a few copies of P96 for Jens by now... you'd think he could afford sponsoring me with a lifetime license for it or something so I don't have to re-buy it, lolb.16:58
mntmnlol yes16:58
mntmnscrooge mc duck16:58
mntmnit's our fault because we didn't buy p9616:59
mntmni mean, the whole package16:59
mntmni am really thinking atm: accelerated cpu + rtg makes sense and unaccelerated cpu + amiga chipset makes sense. in which cases do you need accelerated cpu + original chipset? for demos mostly?17:01
mntmni think personally my amiga would be nice if the games used the most compatible slow cpu and workbench rtg stuff would be as accelerated as possible17:02
_BnuMan, I would hate trying to play a lot of regular games on a standard 68000, haha.17:04
_BnuBut that's just because my first Amiga was a 1200.17:04
mntmnhaha well ok lets say 020 or 03017:04
mntmnbut 060 + old games is mostly a bad combo unfortunately17:05
mntmnso, my a3000 works better for gaming with the default 030 than with the warpengine17:05
_Bnu060 is bad for pretty much everything, yeah. It just happens to be the fastest CPU.17:05
mntmnthe warpengine is only there to make workbench fast... which is maybe a bit nonsensical17:05
mntmnso if i could run workbench and intuition stuff on zz9000... 17:05
mntmn...my life might be improved17:06
apolkosnik[m]Just got to start using WHDLoad for stuff rather than ADFs from Gotek17:06
mntmn(at least once a month when i turn the machine on)17:06
_BnuI mean I'm using WHDLoad stuff.17:06
mntmnme too, whdload only17:06
mntmni don't even have a floppy nor gotek17:06
mntmnthe floppy connector is E M P T Y17:06
mntmni wonder what custom chip stuff amigaos/workbench really needs to live17:07
_BnuAll of them*.17:07
mntmnhaha17:07
mntmnthat's what i thought17:07
_BnuWorkbench can't live without IRQs, CIAs or blitter, even in RTG mode. The blitter part is of course not entirely true, you can make P96 do all of it in software instead.17:08
mntmnblittner17:08
mntmnok interesting. 17:08
_BnuBut from what I can tell, it doesn't work quite properly anyway.17:08
_BnuDespite having been in development for 20+ years.17:08
mntmnschnirectory schnopus17:09
_BnuBut I would obviously rather have a fantasy CPU like the PiStorm instead of a 68060, haha. It's just not very feasible to run it on Zorro because it's so slow.17:10
_BnuNo working cache = no cache problems.17:10
mntmn:(17:10
mntmni see!17:10
_BnuI mean you could do bus mastering in Z2 mode.17:11
_BnuAt ~2.1MB/sec access to the entire rest of the computer.17:11
_BnuGreat for something that doesn't need to interact with it much at all, like a PC busboard.17:11
_BnuMega awful for something like an accelerator.17:12
mntmni wonder if good enough for running workbench17:13
mntmnand yield to the real cpu for gamez17:13
mntmnso it would be a dual core amiga, a workbench/rtg one in the zz and the real metal one in... not the zz17:14
_BnuPossibly, but I'm not sure how that'd work. It's not like the Amiga file system is very friendly to having two separate things accessing it at the same time...17:19
mntmnmhm17:21
mntmnfwiw USB would be a fast path from pistorm to the zz, or ethernet17:25
mntmnfor example, zz memory could present as a mass storage device17:26
mntmnthere is some xilinx code floating around on making zynq a USB gadget instead of a host17:26
mntmn(xilinx doesn't actually have any docs on using it as a host, that's why i used u-boot code for that)17:27
mntmnso if you plug that into pistorm you would have theoretical 60MB/s access17:27
mntmnyou could then mmap that device and plug this into your musashi memory map17:28

Claudeif that stupid usb latency wouldn't be there . 17:44
mntmni think zz9000 has the correct signals to drive Z3 as a master, but not Z2 (OWN is not connected)18:00
mntmni wonder if i could write to chipset addresses over the z3 bus...18:01
_BnuNow you just have to figure out exactly how Z3 bus mastering is supposed to work, since no one ever used it...18:07
mntmnnaja the theory is i assert BR, then buster should give me BG at some point, and then i'm allowed to run up to 8 cycles...18:09
ClaudeZ3 spec explicitly mentions chipram . but not sure about Chipset 18:15
mntmnso i would put an address on the bus and READ or nREAD and assert FCS, right... and then wait for DOE?18:16
mntmnno, wait for DTACK i guess18:16
mntmnlulz i guess i cannot sample DTACK18:17
mntmnFC0,1,2 are also not connected18:29
mntmn> Alternate function code registers, SFC and DFC, contain 3-bit function codes. Function codes can be considered extensions of the 32-bit linear address that optionally provide as many as eight 4-Gbyte address spaces. 18:31
