Thanks! :-) Well, I don't have a real functional diagram at hand at the moment. But basically, it's very similar to this ISA card regarding the SRAM. See link: https://youtu.be/rj1CxmtXPWM As far as I remember, he also has a more detailed description of it on his page. If you are generally …

I think the "Input Level" setting in the mixer application should have an effect on both the external line in and the mic in.

To be honest, I don't think all three are defective at once. It is possible but unlikely. There must be another reason. Especially since it also affects different types LS244 and LS245. The only thing that suggests that all three have a defect is that they appear to be from the same manufacturer. …

Does this card and the drivers allow you to work with protected mode games? Nope, real mode games only. The Action Rewind is equipped with firmware 4.8. From 4.0 onwards, protected mode games should be supported. At least it was advertised at the time. I haven't tested it myself yet. See attached …

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 …

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.
