Soldered a clone of a SoundBlaster 1.xx sound card. This is not a replica, as is the case with Snark Barker, this is an independent project from the distant past (from 1994-1995). The firmware for the microcontroller is also not copied, but developed by the author independently. The author (Jura …

This may not be the case, but SB AWE32, AWE64, SB Live and Audigy have common EEPROM issues - EEPROM contents are suddenly damaged. In the case of sb live, there are no automatic flashers tools for fix EEPROM content, so there are two ways: 1) desolder EEPROM IC and flash it on the programmer and …

Broken EEPROM - often issue with awe32, awe64, sb live and audigy. Try google something like “awe64 eeprom fix”, it may be helpful for you.

This reminded me of my trouble with Snark Barker , for the solution of which I needed to make an ISA8 bus emulator -) In my case, the problem was the broken buffer 74LS245 IC. Is the card normally detected? Does it display the DSP version correctly? I will attach several utilities in the archive …

Will try to install this, but I dont think it runs with CGA out of the box. Unfortunately, most Chinese clones of Saleae-8ch logic analyzers based on FX2LP dosn't have IFCLK pad traced to anywhere on PCB. Vcaptfx2 uses IFCLK pin for external pixel clock source, so this pin must be connected to 14. …

The idea is not new. The main problem is that Saleae Socket API does not allow to receive a continuous stream of data. But.. There is a very similar project using a fx2lp microcontroller Cypress CY7C68013A on demoboard LCSOFT CY7C68013A (like Chinese-clone Saleae 8 ch): https://github.com/y-salnikov …

Oh okay, i found another strange place and patched it. Finaly, CMSDRV.COM now run on SB 1.x with CMS chips well. I tested it with real 486 and Snark Barker with original song disks from CMS (player.exe). Enjoy.

well, your binary crashes my 386, or with QEMM triggers an illegal instruction. :) As I said, everything is not so simple there. I found self-modified code at the end of programm, so code look like seg000:13A1 loc_113A1: ; DATA XREF: sub_11199+3B↑w seg000:13A1 mov ax, 4C00h seg000:13A4 mov dx, …
