For now, I am deleted the GitHub repository. I would be grateful for TexElec that to comment on the license of the scheme of the Resound OPL that they published. As long as this is not clarified, this project that is based on it will not be public.

The monochrome module works well. Conversion from PC104 to ISA should be tested with a PC104 SVGA board, coming soon... https://t.co/vs1wcOPCOf https://twitter.com/spark2k06/status/12655967 … 9744855041?s=20

What exactly does the tool? From the sparse description and screenshots, it seems to create a self-extracting .exe file, which automatically runs the extracted program afterwards..? If that is the case, WinZip can do that since the very beginning. Sure, it does just that using 7z self-extractor …

Some people might want to use that OPL3 card together with something else, most likely SB 1.x/2.0 So it would be nice to be able to disable the 38x port range... 38x and 22x - SB with OPL2, CMS, DSP 24x - OPL3 So, such a configuration could cover all the needs ?: 0 - 0: 388h 0 - 1: 220h + 388h 1 - …

Well, according to this website the ports are: 220h or 240h (selectable) and 388h -> Sound Blaster Pro II, 16, 32, AWE32/64 and Live, ESS 688, etc. Only 388h -> Adlib Gold, Windows Sound System So in the SPLD I will always keep the 388h present and leave the DIP Switch configuration such that: * 0 - …

The configuration is done with the SPLD, and in principle I did not want to touch the design of the PCB unless it was strictly necessary, although the silkscreen of the DIP Switch could be modified according to the SPLD programming, where I can set the I/O ports, or to use several at the same time …
