EDIT: Done so far: + Firmware rewritten to literally match the original SB2.0's firmware behavior (based on disassembled sources) . + The card passes all tests (auto detection, PCM, ADPCM and FM-music) by the original Creative Labs TEST-SBC.EXE utility on a Pentium - even SB2.0 can't do that!! + …

Hello @LABS, what is the current price for a Blasterboard kit? Also, do you have any other projects in the works? :) Hi, the prices are here https://www.vogons.org/viewtopic.php?f=62&t=61098 if you want a THT-version, but you better wait for an improved SMD version which is currently in the testing …

Glad you made it, have fun! :) ...Also I replaced TL074 op-amps with OPA4134... It is nice that you experiment with the sound, OPA4134 is a good choice for this exact circuit without any modifications and it is not too expensive. Haven't seen them from any reliable supplier for a long time in DIP …

Thanks, root and mjay Please, if anyone else ordered an assembled card and has NXP 74HC138 chips in it, let me know if you have the same issue as pan069

The rust looks like what you would get on old C64 MOS branded logic ICs. Bad or no passivation layer on the legs. When did NXP stop making 74 series logic? Maybe they did some crappy ones? The latest datasheet is from 2015: https://media.digikey.com/pdf/Data%20Sheets/NXP%20PDFs/74HC_HCT138_Rev5.pdf …

Hi, sorry to hear about your issues. Are you completely sure nothing was spilled on it? IC13 and IC14 are rusty indeed, but IC15 is fine (the same 74HC138 chip). And that IC12 - very strange. Please pm, will try to figure out why it stopped working.

Nothing at all? :D Did not expect such lack of interest Or did I miss something? I'm always interested in such efforts. Money to actually buy the finished product, on the other hand, is an entirely different matter. :D So, some (hopefully helpful) questions: Do you have a command that allows you to …

I concur, really neat design and features, well done. (also - and slightly off topic - that's insanely cool what they're doing with Adlib Tracker these days - my OPL3 music didn't usually sound like that in the 90's!!) BTW these youtube videos I filmed for suzb3ro (the creator of Adlib Tracker) and …

Hi! Is this different from RetroWave OPL3 Express (previously the RetroWave OPL3) ? DosBox-X already have support for it too... Thanks for the info, didn't know about it.. I made a research about something similar when started the OPi and there was no such thing Strange that it looks ridiculously …
