@Peri NoidGood to hear, that i'm not alone with this kind of problem. Perhaps somerhing with the Phi2 signal. I will use a 78F08 instead of the LS08. That could improve the Phi2 signal.

Yes i tested is with different PSU. Makes no difference.

... yes, with the original GTIA - no problems. All solder points of the socket look good. I use a high quality precission new socket with round holes and the SOPHIA fits very strong. The keyboard couldn't be the problem, because i do my tests without the keyboard in an open case.

I have a strange problem: I have an 800XL that works perfect. With a modern 512KB (Static-RAM) expansion of TF_HH and TK-II stereo. Works great and without problems. Now I have exchanged the GTIA for a Sophia2 and now the computer starts only every second or third power on. Sometimes immediately and sometimes only after five times on and off. The screen stays black and there is usually (but not always) a soft beep on the speaker. (Monitor is not only black, there is no signal) It seems that the Sophia is not initialized at all, because there is not even a clock signal at FPhi0 (pin 29). OSC at pin 28 is present. Operating voltage is stable at 5V. I have already removed the TK-II and the memory expansion. Same problem. Sophia2 tested in other Ataris: Works. So it is not the Sophia Another Sophia (luckily I have several) installed: Error again. So it is definitely not the Sophia. Reset signal tested at 74LS14: Everything looks normal. To be on the safe side, 74LS14 was exchanged. No improvement 74LS08 exchanged: No improvement Also replaced: Sally, PIA, ANTIC, POKEY - No improvement! RAM tested with SysCheck: All ok. Even with SysCheck the problem occurs. So it is not the RAM. To be on the safe side, I tested with an Antonia, who is replacing the RAM and the MMU and the CPU anyway: Error is still there. Sophia out again and instead replaced again with a GTIA: Everything is fine again. The computer starts every time on the first try. I am at the end of my ideas. Do any of you have a tip what I can check, measure or exchange? Otherwise it remains a computer with a purely analog image. I am grateful for every hint.

This is how the new siede- and backpanels locck like:

Tested the PokeyMax with the 10M04 again today. Again played a new firmware, this time the 127M04SC (stereo Covox). Changed some properties and saved. Everything without problems. Now I also got the two Pokeys displayed in the Config Tool. I think the problem yesterday was a looese contact to the A4 Signal.

You're right, that is strange. But i have stereo sound. I will do some more test tomorrow.

I had upgraded today my PokeyMax to the new version 1.27. Has worked fine without any problems. My Pokemax is an 10M04 Model, so we can say, that the 1.27 is also for this FPGA okay. At the same step, i downgraded the PokeyMax from Quad/Covox to Stereo/U1MB. So before the upgrade it was 118M04QC and know it is 127M04SU. But i think i will flash ist again to 127M04SC (Stereo/Covox). Is there somethin special i shoud test for you? Before the upgrade: After the Upgrade:

Sorry, I have a lot of work to do. But I will try this weekend. Then I will post my knowledge here.

... yes, you should write him a PM. Usually you get a reply very quickly and Simius support is really great when you have a problem.

... so if it has no negativ effects, then i think it's a good idea to set this little wire-bridge. I will also connect the EXSEL pin to the corresponding position of PBI. Who knows if I will need this in the future.

I have now read through all 22 pages of this thread and understand that I can remove RAM, OS, BASIC and the two 74LS158 without any problems when the Antonia is installed. What is a little confusing are the statements about removing the DelayLine: Once it says you can remove it but you have to put a jumper between pin 6 and 7. Later it says in another post you can just remove the DelayLine. Is it necessary to bridge pin 6 and 7 or can I remove the DelayLine without this bridge?

Yes, it's a V2 (The old one, not V2b) So i will try the Update to 1.27 I will post here the result, if it worked. But I have an other question, is searched all the forum but didn't found an answer: If i use the Stereo + U1MB Version, and like to switch between Mono and Stereo with a mechanical switch. Do i only have to connect Pin6 (U1MB) over an on/off switch to GND or is there more to do, like an pullup resistor?

Can i use this version also for my 10M04 (116P104QC)?

If possible, i would like to buy: 1x Standard Edition, Germany

... also found a cheaper one on Amazon (Germany): https://www.amazon.de/dp/B09JC83F69 HDMI Audio Embedder Inserter Digital Analog Audio + DVI to HDMI / TOSLINK Optical 3.5mm Jack AUX Audio Input 4K60Hz 18Gbps HDR CEC HDCP2.2 - 49,99 Euro Video Input is HDMI, but you can use a DVI-HDMI Cable or Adapter

You can use something like this: https://www.amazon.de/gp/product/B005G3VQ5E/ (StarTech DVI to HDMI Converter) Input: Audio Analog and Video DVI Output: HDMI Video+Audio

@Simius Great. Thank you for your fast answer. So i will still wait.

Me too. I don't like to order from the US (living in Germany) because of the high postage, customs and tax fees. Now I don't know what to do either. A short explanation from Simius would be helpful!

is there also a seller in Europe or can I buy directly from Simius again?

I am listed with only one device. But i need three: Olix - 3 - DE Can you please correct this? Thank you.

Thank you for the great words and your support. I will definitely finish the porting for me privately. And I could well imagine that there will then be a game for download here in the forum called "Geisterhaus". (The German word for Ghost-House) In this house there will surely be creepy creatures, but neither spiders nor bats

No, but I'm just very careful. There are too many money-grubbing lawyers who are just waiting for someone to violate trademark rights.

Atari has also re-released Hounted House on its "Atari 50: The Anniversary Celebration" game collection. To avoid trouble with Atari I unfortunately have to stop development on my port. I'm really sorry.
