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?

Not trying to modify anything, I just want to see how it's all set up 😀 Thanks, I'll check that section out.

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. …

Old capacitors could certainly be the cause. I'd be able to do it. Not sure where you are, I'm in the US. I'll send you a DM with my email address.

Maaaaybe... I'm not familiar with how a waveblaster works, does it basically just process a serial midi signal and send back analog audio? Yep, here's the pinout: https://www.epanorama.net/documents/pc/waveblaster.html BRESET (pin 15 on the CS4237B) would drive the wavetable RESET input. Is that …

I just ordered a run of 10 boards from JLCPCB! They came out to about $33/each. They were out of stock of the 16MHz crystals and the 3.5mm audio jack and I totally forgot to look for substitute parts. Oops. Anyway, for anyone in the US that's interested (sorry other countries but I don't want to …
