I was thinking maybe you got thrown into the meat grinder going on in your neck of the woods, don't they know this is more important? Fortunatelly no, I'm outside of that scope. Hey man, a quick pcb order is done in a few minutes :) Perhaps do it inbetween? Pretty please? :D I'm glad to make some …

you personally, in my eyes, are very low Do you think I care? Not in the slightest. People want a PCB, you, like goons, cannot provide them with this, so I will do it. Don't pretend to be some kind of Robin Hood, all you do is copy others boards (even when those are defective) and dump those onto …

Hello, everyone. Time for long overdue update. SN PSG block is technically finished (have to order last PCB revision for final inspection). CMS ( Creative Music System ) SAA block was thoroughly tested and source of sound glitches was found: SAA1099 really doesn't like to get power from one power …

Sorry for a long delay from the last update. https://youtu.be/ix2NEqVtKmk I've worked a bit with that "first version" replica and moved forward a bit. First iteration had very noisy and quiet output. That's logical, because all analog parts (opamps, AY, switch) were getting power directly from noisy …

I've also had checked OPL2 debug block ( AdLib -compatible). I was very slow to begin testing this block, so PCB design changed several times before I've got to assemble one. So I've tested version 02. https://youtu.be/A7bA6h1Hsso YM3812 is purely digital IC, it does not output analog audio, it …

Any progress on the FMonster? I also would like to know the latest news on this project Sorry for a long delay from the last update. Yes, there are some updates. I've tested 2xSAA1099 debug block (Creative Music System compatible). It is based on Tronix 's schematics with some changes. https:// …

So in DuoSID both SID chips listen on the same base port? From what i can see there's only 1 base port selection which means both SID chips Will play the same thing. Wouldn't it be better to have a different base port for SID 1 and SID 2? Earlier DuoSID and FMonster had user-selectable port for …

Sorry for necroposting. BUT when i chose LPT1+LPT2 and check checkbox "Stereo" - FastTracker halted. Sometimes, unexpected exit to DOS with debug information about registers and stack. I have the same problem. LPT1+LPT2 simply does not work in FT2. Have you tried this later version of FT2? Does not …

An update on debug block verification . I've tested SID-containing one. Basically, it works as intended: https://www.youtube.com/watch?v=uJK9DpSWL8Y It works with "SSI-2001 compatible" games. And it works with "*.SID" file players. But it has heat problems when using with 8580 SID. I have to look …

this is only the case if you run card at 0c0h and maybe 0E0h on AT+ Systems, all other ports are fine. Oh, so, basically, it is not a problem for me. Because I use my card on default 0x2C0 port with TSR for redirecting 0x0C0 or newer software that can utilize 0x2C0 directly. I think that "0x0C0" …
