Here’s something interesting I picked up out of an old piece of lab gear that was getting scrapped. We have a big metal box full of cards:

Well, inside is a standard ATX board and one of the most complicated ADC+datalogging+power delivery systems I’ve ever seen:

I think it’s neat how the casing is only just bigger than the motherboard itself.

^^ noted.
Here’s the datalogging setup that came out. Three ISA cards and a PCI card all strung together with ribbon cables. These might have had production numbers in the tens of thousands, and possibly cost that much in dollars too. As mentioned, the bottom card also acted as the power supply and was connected directly to the ATX power header on the motherboard.

I wish I had some way to use all this or some application for it. I can think of things to do with more typical multi-channel ADC boards but this is a little intense for me. 😜
With all that removed I powered it on and it fired up to a bog-standard PC BIOS, as I kind-of expected. The mystery CPU turned out to be a non-MMX P133.

I have no idea how this thing was supposed to boot, there was no storage medium attached and no boot ROM on the ethernet card (still installed in the above pic.) Didn’t seem to be anywhere to mount a HDD in its original home. It’s possible it had a DOM fitted that was removed before the instrument got shoved out to disposal.
