..making a card that has compatibility with both SB Pro and SB 16?.. I actually have a half-working prototype of a SB16+SBPro-compatible card with CD SPDIF in, OPL3, MPU-401/Waveblaster, analog mixer, SPDIF out etc based on a new ATmega4809 MCU . But it is moving very slowly. There is already an …

Hello everybody, here are some news: A minor firmware update v2.1 has been released: Added SB16 commands for 8-bit signed samples playback (C0h and C6h). These are used by FreddyV's Mod Master. BlasterBoard became a bit more tolerant to some software running on faster computers like Pentium II and …

Did you know that BlasterBoard's CD input can also be used as a stereo Line input? You can for example plug in your internal/external MIDI module and control its volume manually. Here is my current perfect combo: Filename combo.jpg File size 755.04 KiB Views 431 views

What do you mean it is not detected on boot? SB 2.0 utility may not detect it if it is run on 486 or faster machine. Did you solder IC14 wrong at first and powered it up? It might be damaged then. Is OPL2 working? If the led did not light up - you will not hear any sound (check T1 MOSFET if it is ok …

Looks good. I'd also check the DAC (when removed) in continuity mode. Pins 3, 13, 14 and 15 are in question and should not buzz against pin 2 (GND) and between each other in both ways (switching probes).

Remove SnarkBarker from the machine and check PC's power rails first. On white 4-pin Molex connector black wires are GND, red is +5 and yellow is +12. Google your motherboard and find where you can measure -12V as it is absent on Molex. When, after you install new ZD2, install SnarkBarker and check …

Vref- = 0V is good as it is GND. Firstly you should check the power rails of your machine with SnarkBarker removed. You need +12, -12 and +5 rails. -5 is not used. If they look good - remove the DAC (U12) from SnarkBarker, install the card and measure all local supply points, i.e. outputs of ZD1-ZD3 …

I'd measure reference voltage on pin 14 of U12 (DAC). If it is not 5V then the clipping may occur. If it is not - check R38 and voltage drop circuit ZD1, C46-C48, R21. And make sure R22 and R25 are 27k.

All orders are shipped. Currently out of stock, but will be available at the end of July. Please preorder now if interested, as half of next stock is already sold out. The quality of this soundcard is really impressive. I just have to ask - is there any chance you would consider doing an MCA version …

...although I prefer the green PCB, too... Yes, greens have more retro look, but after situation with pcb copying, thick solder mask is a weak, but at least some kind of protection. And I preferred white over black one. ...Also tried to install / dignose the original SB drivers. No luck at all. …

Does that mean that I read the markings correctly on the inductors? Not exactly, brown/green/brown/silver = 1/5/1/10% = "1" + "5" + 1 * "0" = 150 uH with 10% tolerance Not sure if we are misunderstanding each other and you are talking what the markings should be for it to add up to be 150 uH, but …
