| + NoctisBE1 (~sgilissen@d54C34CDE.access.telenet.be) | 15:42 | |
| NoctisBE1 | OK so, a few potentially dumb questions | 15:48 |
| NoctisBE1 | concerning the issues I have with the flickering image. My A2k has a converted ATX PSU, so it's not using the tick signal. That shouldn't matter, right? | 15:49 |
| NoctisBE1 | Also, I've rerouted the flatcable and even tried several straight-through floppy cables, but the issue remains the same. Yesterday I had a fairly stable image for a while in the early startup menu but that doesn't seem to be the case anymore. I'm starting to think my A2k is haunted :P | 15:50 |
| apolkosnik[m] | And you have J300 set to the internal tick? | 15:52 |
| NoctisBE1 | Yep. The machine won't work at all without that | 15:53 |
| Jope | the tick source shouldn't really matter for this | 15:59 |
| Jope | the video frequencies are derived from the master oscillator in any case | 16:00 |
| Jope | if you had PSU tick, it would go to one of the CIA chips for timer use | 16:00 |
| NoctisBE1 | I think the only thing for me that's left to do at this point is to completely take out every component and the mainboard, and see if I have any cold solder joints or anything like that on the mainboard :/ | 16:01 |
| NoctisBE1 | Went over every solder point on the video slot now, basically reflowed each and every one of them. Did not change anything. | 16:29 |
| NoctisBE1 | I'm really at a loss at the moment | 16:29 |
| NoctisBE1 | the regular RGB output does not give me any issues either | 16:29 |
| NoctisBE1 | Even tried several monitors and HDMI cables | 16:29 |
| apolkosnik[m] | You could just look up/trace the lines going from Denise to the video slot | 16:31 |
| apolkosnik[m] | I was doing something similar on my A3000 due to the Varta destroying a via on the pcb of one of the audio channels going to the riser | 16:33 |
| NoctisBE1 | Hmm. I've been tracing them all, but I can't find any visible issues atm. They still look like new | 16:35 |
| NoctisBE1 | the battery of the A2k is nowhere near the Denise chip | 16:35 |
| apolkosnik[m] | I used to get distortions when playing square wave tests in Amigatestkit on my A4000, I had to route the video slot cable over and under the bottom of the ZZ9000 card. | 16:39 |
| NoctisBE1 | Just to be absolutely certain | 16:54 |
| NoctisBE1 | the connector on the breakout board for the flat cable, that should point outwards, right? | 16:54 |
| NoctisBE1 | I feel stupid for asking this but, you know | 16:54 |
| minute | NoctisBE1: you would get nothing (and potentially fry stuff) if it was wrong | 17:01 |
| NoctisBE1 | Yeah, I figured as much. I honestly don't know what to do anymore at this point. I've tried reseating the Denise chip, tried 4 flatcables (all straight through), cleaned out and reflowed the video slot + Denise chip socket and traced all the lines between Denise and the video slot using a multimeter | 17:05 |
| pasik | NoctisBE1: and zz9000 firmware up-to-date already? | 17:15 |
| NoctisBE1 | Tried several firmware versions. Currently using the latest 2mb one | 17:15 |
| pasik | ok | 17:16 |
| NoctisBE1 | It seems I'm not the only one with this same issue... https://community.mnt.re/t/scan-doubler-with-angus-generated-tick-scrolling-picture/222/4 | 17:24 |
| - mnemotron (QUIT: Quit: Quit) (mnemotron@194.135.47.239) | 17:25 | |
| NoctisBE1 | So it seems that it does have something to do with the TICK signal | 17:30 |
| Jope | you'd imagine a4000 users having a terrible time in this case.. | 17:30 |
| NoctisBE1 | Unfortunately I don't have an original A2k cpu (which was the reason I replaced it with an ATX PSU). | 17:31 |
| NoctisBE1 | I mean, it could be something A2k-specific | 17:31 |
| Jope | it is true, the tick signal does go to the video slot | 17:32 |
| NoctisBE1 | and if you use an ATX power supply, the tick signal gets generated from the vsync | 17:37 |
| apolkosnik[m] | https://amiga68k.com/?product=tick-signal-generator | 17:40 |
| Jope | I'm now wondering about this | 17:40 |
| Jope | the 3k and 4k use the same firmware, don't they | 17:40 |
| Jope | so in this case it works fine in pal and ntsc machines as far as I know | 17:41 |
| Jope | at least in my pal a4000 it works totally fine, the zz shows pal and ntsc custom chip modes totally ok | 17:41 |
| apolkosnik[m] | https://www.retroez.com/store/FULL-KIT-Amiga-2000-ATX-Adaptor-Plate-Motherboard-Loom-Plastic-Bracket-Molex-to-Floppy-Cables-&-Screws-Excludes-PSU-p404528440 | 17:41 |
| Jope | bnu, minute, do you use the tick for something in the zorro 2 firmware? | 17:41 |
| minute | no, but we have heard here before that the tick makes a difference. | 17:42 |
| Jope | but how/why :-) | 17:43 |
| minute | i don't know. just anecdotal evidence | 17:43 |
| Jope | yep, doesn't fit in my brain | 17:43 |
| Jope | if you have PSU tick, it is always the mains frequency no matter what you show on scren | 17:43 |
| Jope | if you have vsync tick, it changes depending on what your mode is | 17:43 |
| minute | i remember someone fixed their problems by changing something with TICK | 17:43 |
| Jope | minute, do you have mains or vsync tick in your 3k? | 17:44 |
| Jope | I remember you had an ntsc machine in a pal world.. | 17:44 |
| NoctisBE1 | apolkosnik[m]: Thanks! | 17:46 |
| apolkosnik[m] | it goes into CIA's 19 pin | 17:47 |

| Jope | soo .. | 17:50 |
| apolkosnik[m] | It would help to capture the waveform diffs between both positions of J300 | 17:50 |
| Jope | but why | 17:51 |
| Jope | if the zz9000 doesn't use the signal | 17:51 |
| Jope | https://mntre.com/media/ZZ9000_info_md/zz9000-manual.pdf tbase is NC | 17:52 |
| NoctisBE1 | Wild guess here, but interference due to it being generated from vsync? | 17:52 |
| NoctisBE1 | If you look at the YT vids I posted earlier, it's definitely a sync issue | 17:52 |
| Jope | ok, now I get you | 17:52 |
| Jope | vsync waveforms are interesting | 17:53 |
| NoctisBE1 | It's an Amiga. Commodore weren't exactly known for not fucking around in the hopes that it randomly would work accidentally :P | 17:53 |

| Jope | hmm | 18:00 |
| apolkosnik[m] | _VSYNC is inverted signal, so maybe it's not latching at the right spot | 18:01 |
| Jope | yup yup. I agree, it's worth scoping around a bit | 18:03 |
| Jope | I wonder if my 2k stilll has working psu tick. it might not | 18:03 |
| NoctisBE1 | If anything, I'd be more than happy to test stuff out on my machine. I did order a tick generator just now, but if stuff needs testing let me know :-) | 18:06 |
| apolkosnik[m] | Funny, TBASE actually doesn't make it to the J8 connector | 18:44 |
| apolkosnik[m] | and _VSYNC comes directly from AGNUS | 18:45 |
| apolkosnik[m] | doesn't make it == the pad is not connected to anything | 18:46 |
| Jope | j8 = the flat cable between the video slot board and the zz9000? | 18:47 |
| apolkosnik[m] | yes | 18:48 |
| Jope | yeps | 18:48 |
| Jope | but the idea about the vsync signal getting ruined when it is routed to tick is an interesting one and worth pursuing | 18:49 |
| Jope | one difference in the a4000 vsync line is, that there is a 100pf cap to ground between the 47 ohm resistor and pin 12 of the rgb port :-) | 18:54 |
| Jope | otherwise it makes a lot of rounds in that machine too | 18:54 |
| minute | ah, interesting indeed. maybe it gets loaded too much? | 18:55 |
| Jope | yep, didn't think of that possibility before NoctisBE1 said it there | 18:58 |

| apolkosnik[m] | I wonder if desoldering one pin of that cap will make a difference | 19:16 |
| apolkosnik[m] | It's not present on A3000 and A4000 | 19:20 |
| Jope | ah.. the emi filter in the 2000 does the same thing as the 100pf cap in the 4k | 19:28 |
| Jope | forgot that they had a cap inside | 19:28 |
| apolkosnik[m] | but it's after a resistor | 19:30 |
| Jope | same as in the 4k | 19:31 |

| gdonner | oy vey lol | 22:44 |
| gdonner | I checked to make sure my A4000's 1.11 BOOT.bin was copied OK, and it's not corrupt or anything | 22:45 |
| gdonner | anyway, hopefully some of this helps! | 22:46 |
| gdonner | (BTW, the AHI Prefs crash is a requester crash; not a black screen guru, if that helps) | 22:47 |
