Does anyone have some guidance on how to make a SB-LINK cable to connect a sound card to a SB-LINK header on a motherboard? I imagine I could probably hack up an old CD audio cable, but I don't know the pinouts. I'd like to do this with the least amount of trial an error.

Thanks.

Can you buy those components and a crimper anywhere? Shoot, I have nothing like that laying around. I suppose I could solder each wire, but I'd rather not do that.

You don't need a crimper for these. keywords: female 2x3 RM/Pitch 2.54
In Holland or Germany you can buy such things at Conrad mail order.

Is this cable the same pin-for-pin on both ends? I've been staring at the picture and I can't tell how those plastic connectors work with the wiring.

It has been a while since I messed with it, but that is what it seems to be on the photo.

Here is more info on the signals, as found in an Asus P2B Manual. DGND / 'Digital Ground' is easy to verify.

Is it enough to replace real or DIY one?

Just $1 for each.

Now that we speak about this SB_LINK stuff, is Sound Blaster AWE64 PCI the only card with a SB_LINK header?

I have this header also on my IBM PC 300PL and I haven't been able to secure one single card that uses this stuff.

Can anyone point me to a source for a SB-LINK cable here in the US? I'm playing around with building a DOS gaming box and have an old SE440BX-2 board with a PC/PCI port and need the cable to attach to my Yamaha PCI sound card

Thank....

what for is the SB-LINK cable exactly? Which emulation does work and does not work without that cable?

In simple words, SB-Link provides the DMA and IRQ lines of the ISA bus, so that old DOS software can program - or see -
PCI sound cards exactly the same as ISA sound cards. Unlike the other methods, this is no emulation per se.

PC/PCI carries ISA specific I/O information over these external cables. DDMA allows those same signals to be carried internally over the PCI bus, but it requires a compliant PCI controller. DSDMA/Ensoniq AudioPCI/Aureal etc. do it with software tricks.

There shouldn't be anything special about SB-Link cable, therefore any 6pin ribbon cable would work. From AliExpress one can buy such cable for less than 0.50$.

Just buy a pack of female to female dupont cables and connect the pins individually. If you really want, you can use electric tape to on either end to bundle them into 2x3 connectors.

...or you could just saw a random old floppy cable or COM breakout into pieces or go to town with a soldering iron ;)
