I need this thing to drive a voodoo 1 along with the other components. I think you are expecting a little too much from picoPSU 🙂 Well, that was the main thing point of my original post, Pico PSU is a bit too on the edge for old systems, and I wanted to know if there are better options that would …

Are you using an original picoPSU or a Chinese knock-off? The Chinese ones can't power ****. The original picoPSU on the other hand successfully powered a Pentium4, a P233MMX, a 386... all with discreet cards for VGA (not a 3D accelerator of course), sound (SB16), CF card, CD drive, and 2 floppy …

I've recently been facing difficulties trying to power a small industrial pc with a Pico atx PSU going in to an AT adapter, bottom line - not enough amps. This led me down a hole looking for better solutions, as I don't want to have a tidy little pc and chonky atx PSU with a rats nest of cables …

I second that, master/slave is finicky with CF cards. You usually have better luck with 'industrial ' type cards in that scenario. I have a 486 that I was trying master/slave with a cd ROM, and it would always lock up, until I tried an industrial card.

I put together a pc using a shuttle xpc ss51g barebones system, I think it was when they finally got an AGP slot, so could be the same. Anyway, it was a P4 and I paired it with the then new 9700 Pro, it kicked so much a55.

Check this, you may already have the newer chip, depends on revision. That said, if you have the older chip, you should be able to swap it, it's pin compatible, and some revisions do have the chip. Re: Asus P2B-F Slot 1 Retro PC

From my personal experience fighting this exact scenario, of trying to get a CF card to behave in master/slave config, it was 100% the cards I was trying at fault, not the adapters or cables. You have to get a card that *truly* supports master/slave, most industrial cards do.

By 'same as last one' I meant the version where you increased the pads going under the chip, to which we determined makes that much better for hot air soldering, but still difficult with an iron, hence why wider pads to the outside direction could help with that I'll try and get that printed/checked …

We printed the PCB, the SRAM pads look quite the same as the last one, you did link the latest version? Bottom line is it can be soldered by someone who is good, but to make it possible for less capable people (myself 😉) the pads could be maybe twice as wide, to the outside direction.

@rasz_pl if you feel there is nothing else to tweak/test, I could order another set of boards, and confirm the revision is working.
