Nice chart! 👍 I have a couple of suggestions for additional columns, if you're interested; 1. approx. price, 2. BIOS support (AMI or Coreboot+SeaBIOS). Also, the EX is often spec'ed at 300 or 400 MHz - but in my experience it runs cool and rock solid at 500 MHz with a little bit of active cooling. …

Seems like the SOM304RD-PI (Vortex86DX as well) would be a good candidate for an ITX or mATX board. No onboard VGA, but it does have native PCI and ISA available at the same time. No branch prediction on that CPU though. The only other one DM&P has with both PCI and ISA is the Vortex86SX which is …

I wonder what the spec'd drive current is on that line? I'd feed a transistor gate with that pin rather than use it to run an LED directly just to be cautious.

I printed the case using Hatchbox grey PLA for the bottom half and PrintedSolid Jessie 500 beige PLA for the top half and buttons and I'm quite happy with that color combo :) I was going for a 90s Packard Bell desktop look and it definitely hits that note. I did modify the case a bit for extra …

The Intel L440GX+ board is just a convenient example of one that has such a PCI-PCI bridge, I assume?

2. YMF744 MIDI controller/driver does not like sitting behind a PCI-PCI bridge - we need some help from the community to test a regular YMF744 board on any period correct server/workstation motherboard that has a secondary PCI bus derived from an Intel/TI/DEC PCI-PCI bridge chip. For example, an …

Oof. @NinjaWarrior are you in the US? If so I can re-flash it, I've got a TL866II programmer and an SOIC clip. USPS priority flat-rate isn't too bad, I think about $10 each way?

Question on the crossbar config, I'm looking at crossbar-tinyllama-rev2.1.bin and the Vortex86EX datasheet. The first byte corresponds to Port0, right? in the crossbar.bin it's 0x41, or 0100 0001. The datasheet says for the first 10 bytes of the crossbar config only bits 4-0 of each byte are used …

I got my boards back from JLCPCB and got the crystals and audio connectors soldered. Also bought a cursed USB-A to A cable and programmed the HIDMan on all of them. I've attached a picture of one of the boards after adding the crystal and audio jack, and then top/bottom pics of one fully complete. …
