TG77 can do things the FS1R can't and vice-versa. Besides the 6 FM ops vs 8 FM ops, the TG77 can modulate AWM with its Advanced FM synthesis as well as import samples (RAM cards) and use AFM, whilst the FS1R can do Formant synthesis which sounds like freaky vocoder stuff. Yamaha OPL4 should've been …

^^ 16 MHz was an undocumented FSB setting on the board, and before de-turbo was applied. I distinctly remember the 16 MHz number, and this was found by starting at 66 MHz FSB, then downclocking the FSB incrementally using the boards dipswitches - 66, 50, 40, 33, 25, 16. Then the fan was disconnected …

I know this is working on PODP83 Are you sure this works on S4/S5 overdrives? Last time I checked removing the fan was not changing mutliplier but applying a different sort of throttling. At least when measuring frequency by TSC There seem to be a myriad of 'overdrives' out there. I've tested two …

That's common to all the POD CPUs, I pulled the same trick on my PODP83 to get it running at 1x whatever I set the board at (16MHz was lowest iirc, but that was with 32b 486 bus) Nice thing about this Socket 5 setup and POD200MMX was that it also ran stable at 3x multiplier and 80 MHz FSB, meaning …

Most OPL alternative sound cards have issues with 2/3 bit ADPCM. Regarding OPL, ESFM has issues with one of the tracks in Tyrion 2000. Dune is a good litmus test for OPL as well. Crystal FM can sound a bit thin at times. There are other clones that I haven't tested much of yet, and there's the …

Would I gain reverb & chorus options for the OPL synth of a SB Pro / SB16 soundcard, when adding either a Creative Waveblaster II (CT1910) or a Creative AWE32 upgrade card (CT1920)? You need to feed the line outs from your OPL sources into external DSPs for effects processing such as chorus, reverb …

What I see on some boards above is the IC376 which is the same chip as on the original WaveBlaster and predecessor of the EMU8000 (not an early version of it). There is no dispute that evolution of these early chips eventually lead to the EMU8000. I would rather say that the EMU8000 used some tech …

What is the lowest clocked build you can get on AM2/ AM2+ sockets? I recall seeing somewhere on this forum around 300 MHz - is this possible? I have some parts and wouldn't mind building one that clocks this low and is Win98 compatible.
