Re: VGA Capture Thread

There is a transcoder called the koryuu that converts composite and Y/C to component that's designed for use with the OSSC Hrm, but you can also use the SVideo from the C64 directly via scart and then use it as composite in the OSSC, but this has worse picture than SVGA. I doubt that the koryuu …

Re: SIV support for 386/486/586 class + Alpha CPUs and 3dfx + S3 + SiS + Matrox + XGI + old ATI + NVidia GPUs - Testing

Oh the duplicates are due to the different monitors that I used with this system, it's nothing to worry about. I never changed the GPU in this system, it always was a S3 Trio64V2/DX, although I did put it in different slots, so that's possibly why multiple monitors show up.

Re: SIV support for 386/486/586 class + Alpha CPUs and 3dfx + S3 + SiS + Matrox + XGI + old ATI + NVidia GPUs - Testing

Hi I've since managed to fix the 430VX system, it turned out that it wasn't the VRMs but rather there was a jumper that raised the Vcore voltage by 2.5% and apparently the older P133 could handle it fine, wheras the P233MMX couldn't without becoming unstable! After closing that jumper now it's all …

Re: Compaq Advanced VGA EISA setup problem

Looking at pictures of the MAE486 board online there's two Dallas RTC chips, one is for the EISA (the "DS1225Y nonvolatile SRAM") config the other for the RTC and BIOS settings (the classic "DS1287 Real Time"), these two chips have integrated batteries. A common fix is to file down the chip's …

Re: Need help with MPU401 standard mystery.

From what I understood, Sound cards usually are emulating a MPU-401 in UART mode (or "dumb" mode) which works with most MIDI modules but not all. There's some MIDI modules that require an "intelligent" MPU-401 interface, that's where the Midiman/MQ/Roland MPU-401 interface cards come into play.
