You can still buy new motherboards with ISA slots. Lots of industries need these. https://duropc.com/product/r6029-4p5i-4

For how long?

That board uses a chipset that has been out of production for 9 years.

The newest CPU it supports was released in 2017, and has been off the market for 3 years.

Rather sooner or later, someone is bound to implement that with an FPGA. Many already come with native PCIe blocks and a more-or-less powerful microprocessor to deal with DMA and whatever.

Here's a newer one: https://www.dfi.com/product/index/1502

I never understood how these motherboards work given that they look more like expansion cards. Now I know the intended way is to plug that into a backplane and wire the bus interfaces out.

The mainboard is the card and the part with the connectors is just a passive backplane.

Ah picmg, we meet again. I have a Pentium chassis like this for retro stuff... I would like the full gamut of processor cards (8088, 286, 386, 486) for this.

Yeah, generally with a hefty price tag.

This open source design makes good use of TPM ports present in most modern motherboards, including current generation, thus it should bring ISA access for everyone, on the cheap.

> present in most modern motherboards, including current generation

I don’t think current generation motherboards are commonly carrying LPC interfaces having been replaced with eSPI.

The motherboard in the video is stretching the term modern being a Sandy Bridge era - ie a decade old.

They broke TPM port? Old TPMs can't be plugged into new ports and the other way around?

This seems so messed up.
