Hi guys, as far you know for example the unpatched Roland SCB-55 REV 00 or SCB-7 cards have reversed L/R channel outputs. The quick test to them is in Doom 1 game E1L1. When the first riff comes from the right channel the channel order is correct. Could anybody tell me how to confirm the channel …

Yes, mine supports a DOS utility I made (and I plan to add Win16 and Win32 apps at some point, and possibly Linux for a laugh) to control, as well as plugging in a Crystalfontz USB button/display module which gives you menus you can use to switch disk images/etc. On top of that you can control it …

Yes. All analog inputs work now! Thanks. It is amazing project. My favorite card is Audigy SB0090. This one has a working SPDIF02 IN on AUD_EXT header as you mentioned according to the SBLive! cards.

Hi Parus, thank you for you great work! The mixer works perfect. I tried it on CT4620. I have found only one disadvantage and it is that I can not to mix two audio analog signals together (for example CDIN + AUXIN => SPDIF OUT). It is not a matter of your MIXER but all analog inputs are a part of …

I am really impressed with your sound card. Great work!!! I definitely want 2 of your cards from second fixed batch. Please count with me. Could you add on your card these a 4-pin header on Line OUT or a 4-pin PCB connector (like for CD-ROM input) for internal connecting between the sound cards? It …

To Feipoa. It is a little off topic but I bought this mainboard P4U880A/IO V1.0(S1.2). See the picture. You wrote me that if there is AMIKEY chip onboard that there is possible a PS/2 mod. I am planning to desolder the AMIKEY chip and rise this chip on the DIP socket like this and use this USB to PS …

Hmm. Look like 486 SPM is really fast. I got some 32MB 50ns EDO single sided SIMMs and it seem that this motherboard do not support them. Is there any advantage caompared to FPM? And how fast is compared to famous Aopen AP43? Are there any tests? Is it possible to make PS/2 mod for AP43 too? Thanks …

I thought that the rest parts are required only for volt regulator. I dont have SMD capacitors 47 pF right now. It will take a few days. I let you now than. Thank you.
