Ugh, my replacement sound card arrived but is too short to connect my DB60XG clone up to.
Any ideas how to deal with this?

I could have sworn there was a post here somewhere about this very thing but 10 minutes of searching has not found it. 🙁

🙁
A few more days of searching and no luck.

[Edit]
More details:
When the daughterboard is attached, the sound card will no longer fit in an ISA slot.
The daughterboard goes down too far and touches the motherboard before the sound card is in the ISA slot.

Misplaced WB headers are quite common on third party soundcards. You can try to use a cable, like a floppy cable. Then fix the daughterboard somehow electrically safe.

Looking for this: The Yamaha OPL YMF718-S chipset.

That looks to be it, the floppy cable sounds like a good idea.
I can also sacrifice part of a HD/CDROM controller board so I can solder a cable to it's pins, I guess.

I'll post pics if/when I get it done 😀

So I bought a 26 pin make connector and butchered a floppy cable...
I am going to test it with a multimeter to make sure there are no shorts/etc but I wonder now...

What is the worst case scenario if something is backwards?
Really paranoid here but I don't want a smoked sound card and or daughterboard.

worst case scenario? a smoked soundcard, daughterboard, motherboard, ram, fried PSU...short in the wall causing fire!...The fire spreads to the entire area, Burning down a nuclear reactor!! AND KABOOOM!! GIANT MUSHROOM AND MILLIONS OF PEOPLE HOMELESS!!!

Is it really worth it?

If it can point an asteroid towards Earth as well, then yes!

Alright, on a more serious note. Afaik reversing the cable will 'usually' result in a short. The major exceptions are IDE cables and MOST floppy drives connected to a reversed floppy cable (some very old proprietary oem floppy drives might get damaged if you reverse the cables).

I have kinda the same problem, wanting to try out an old ISA video capture card I have. As I don't have any of the original cables I'm gonna be forced to use the 26 pin feature connector and I sure as **** don't want to break it by attaching the cable the wrong way! 🙁

And I think if you connect scsi drives reversed, it'll get burned as well.
Same with old processors, fit them the wrong way and bad things will happen.

So there are basically 2 things you, and I, can do. Either find some original documentation, or connect pin 1 to pin 1.
Sometimes pin 1 isn't marked as such but I found that if it isn't, often the solder dot of pin 1 is a square instead of a circle, so to say.

But I still find it very odd that a daughterboard which is, as far as I know, made for your particular soundcard connector can't fit.
I think the suggestion elianda posted is the best one. Just make sure you connect pin 1 to pin 1.

But I want to emphasize that I'm not really home in this material. I've never even used a soundcard daughterboard before.

Just make sure the pins are connected the same with the extension cable as without the extension.

I checked with a multimeter, down one row has the right voltages but...

It's always on the damn opposite pins as the daughterboard!
RAAAAGE!

I can't figure out how to swap it 😒

IT'S BLOODY MIRRORED!
The cable was probably correct all along, keep this in mind if your pinout is for one half. (in my case was the female wb connector)
