Your blasterboard vs SB 2.0 what you learned about preventing noise that SB 2.0 had?

I'm curious.

Cheers,

Damnit, you had to go and make the card all sexy-like 😀 Now I sorta desire another one.

I'll try to do my best to solve SB 2.0 drivers issue for w3.x, but I'm surprised that some of you guys have a separate card for that instead of using a better sounding BB with SB 1.5 driver, which works just fine. Any practical reason/titles? I already tried to solve it, but failed so far and switched to more important updates. However, if there is such a demand, I should disassemble the driver and look under the hood..

I found an old article recently that mentioned problems with the Sound Blaster 2.0 drivers. The article claimed that the standard drivers tended to have problems on any system faster than a low-end 486. Creative released a "fixed" version, which the article claimed didn't work much better; they still had to disable the on-board cache just to get it to install properly. Their proposed solution on faster systems was to use the older drivers for the 1.5. Hopefully that can give some hint about what is going on.

There's something that makes me wonder - what about using the ThunderBoard drivers, then ? Could one of them be used with BlasterBoard, perhaps ?
If memory serves me well, the original ThunderBoard was supported out-of-box in Windows 3.1 by a separate driver entry.

I was wondering, besides the new PCB color, what the differences between these two revisions are?

Removed the led, changed 2 voltage regulators to another type and made some minor layout ajdustments for easier assembly. Nothing that affect performance.

Hello Eugene, I've received my board yesterday, so thank you!
And btw, I've read that the original SB 2.0 was apparently one of the few soundcards that needed a -5V rail? Would this be the case for the Blasterboard as well, or can it be operated without one?

I‘d wager a no. The Blasterboard is an original design. And I didn’t have any problems with it on an ATX power supply.

Hi, glad to hear, no BB doesn’t need -5v, only +5 and +/-12.

I just received my kit today and I was trying to catalogue all the components and I have a question about the inductors L1 L2 and L3. According to the manual these should be 150uH but as far as I can tell the ones I have are 220uH, the colors seem to be RED RED BROWN, but it´s kinda hard to tell the colors apart. In all the assembled pictures I see the colors are the same as the ones I received so I assume there´s nothing wrong with the components but I´d just like to be sure I´m putting the parts in the right place when I start assembling the kit 😀

Thanks for pointing that out, I'll check on this. You can safely assemble your kit with the included components.
