Oh ok. If the reset mechanism already works, it's a start. 😀 had you checked the board for loose pins? especially on the pins on the chipset?

what comes to mind spontaneously, should the reset LED on the POST card go out shortly after the mainboard was started? or did I understand something wrong?

That’s a step forward. 😃 If you post us a current photo of the board, we can take another look on it. Maybe someone notices something. Do you have such a POST card analyzer?

TheMobRules is right about the short circuit. I have often noticed this behavior of the PSU in the event of a short circuit. I think I would check everything again. All soldering points, polarity of the caps, short circuit on the caps, etc. If you can't find anything here, then I would also check …

Please improve the edge connector. Ensure it is properly beveled and rounded, pull back the solder mask from it, and at a minimum use ENIG (hard gold would be 1000x better) Thanks for the comment. The final revision will definitly be at least ENIG. What exactly do you mean by properly beveled and …

Hey guys, I wanted to show you to my latest project today. Currently I am working on a clone of the Datel PC Action Replay card. I was fascinated by the card when LGR showed it. If you haven't seen the video yet, check it out. It is really worth seeing! The project has been with me for a while now …

It is very likely that the problem is with the RAM. Just like maxtherabbit said. I think there is also a setting in the BIOS. Otherwise, if in doubt, always use FPM RAM with 486 boards.

That's how I see it too. If you take the development time and its costs into account, the price for an assembled board is really very fair. Even if a small surcharge is probably included in the PCB price. It should also not be forgotten that these are not mass-produced goods from Asia, but …

I can recommend the adapter. It works absolutely reliably for me in my 486 socket 3 machine. I have revision 1.1 of the adapter. Rio444 is super friendly and very helpful. Highly recommended!

cyclone3d, thanks for the information and photos. The "old" clones are probably as rare as the AdLib Gold itself. I think an AdLib Gold Clone should be as close as possible to the original and fully compatible. Clearly the CTRL chip and probably the MMA have to be replaced by FPGA or CPLDs.

The Gold Ctrl IC will be the major problem... Would probably need an FPGA replacement or similar. Yeah, probably. I'm doing something similar for Datel PC Action Replay right now. I think it can be done. I am more concerned about the calculation of the filter capacitors. A (defective) AdLib Gold …
