  1. So the first thing to do is to see if all cables are properly connected. Maybe change the power cord. Then use a different power supply / transformer. If you have a circuit diagram, you should measure whether the voltages are correctly applied everywhere. If you don't understand anything about measuring, I would have re-soldered the soldering points in your place. Just heat it up again. They don't look really fresh anymore. Maybe you have a cold solder joint somewhere on the board. I've already had that on one of my VIC-20s. I don't know the circuit diagram, but does the left capacitor leg touch the contact on the right? It would certainly not damage your board or the contacts if it was cleaned with isopropanol. Do everything at your own risk.
  2. I really dont know what a HFDC is. But, have you already tried another transformer / power supply?
  3. I find it very interesting to see your modifications, folks. However, I would find it even better if you would write a few lines about it. What exactly do we see for hardware? What is the purpose of the modification? How does the system look in operation? For example, I ask myself that right from the first post. Where is the keyboard left? So a little more detailed reports gentlemen. Cheers Sid1968
  4. Without knowing Ralph's situation, you shouldn't forget that because of the looong lockdowns, a lot of people have great existential problems in Germany.
  5. Danke Ralph, für Deine zielführende Arbeit an Deinem Projekt!
  6. Very nice. I just found one PHA 4100. Its the eBay item number: 233638508996. Unfortunately sold as defective. Is in the USA ... does anyone know the country? The postage to Germany is "only" US $138,70. Somebody should grab and restore it.
  7. Thanks buddy, as you can see from my thread, the installation has already succeeded. Mame runs with me. But as soon as I use parameters it doesn't work anymore. However, I am not a TI-99/4 expert and cannot script either. That's why I need help on the two points mentioned above. I had already described that in the first post of the thread. 😉
  8. Hi Mate, i enjoy your youtube channel. 👍 Without knowing TI99Sim in detail, I believe I can say that your project cannot be realized with it. I myself had a similar idea under this post: As a joint project of this forum I would like to create a guide: "How to run the TI-99 / 4A MAME Version on a Raspberry Pi 4". The emulator with which the project would be realized is MAME. In the first post I describe what the goal is. Extra wishes are welcome. So far, I haven't managed to 1. get Mame up and running with the desired parameters and 2. write a start script. Unfortunately, there has been no help with it so far ... although one of the Mame developers is active here in the forum and should actually have an interest in the project. But maybe you have the desire / knowledge to help achieve the goal. Cheers Sid 🙂
  9. Aahhhh .... They are sooo old ... You definitely don't need them anymore, do you? 😁
  10. And you really made that right, Mate! Not having them is definitely an advantage. 😁
  11. Hey Schmitzi, are you still alive or do i have to call the firefighters?
  12. Yes, you are almost correct. But you are wrong that I can do it, and certainly not in 30 seconds. So far I have not been able to start mame with the previous parameters. I got only errormessages. That's why I started this thread. I did what I can to help resolve it. I am not just asking mizapf, but everyone who can create a menu as described in the first thread. It should be in the interest of the TI community to run an emulator on a Linux platform like the Raspberry Pi that is easy for EVERYONE to install. That is the goal of this thread. Cheers Sid
  13. It behaves like a real one. Use the keyboard to select game. Use the joystick ingame.
