A very nice system compilation. I would bet anybody here would be jealous of it. The SV2GX4 (Rev 2.x) is a dream for a Socket 3 VLB 486. Also your soundcard combination leaves nothing to be desired. For my taste an Am5x86 is rather a low-cost Pentium alternative from the year 1995/96 and does not …

I would also recommend a Voodoo3. The 3DFX drivers have excellent 3DNow! (Important for K6 CPUs) support (in OGL, D3D, Glide), better than ATI nVidia and Matrox. Also, the driver overhead is very low. Alternatively, a GeForce for DX7 games with T&L support would also work nice, but the K6 is usually …

You have to find and check the data sheets. There is no save way to identify it optically. In general DAC ICs with DIP layout are crappy. The frequency rating should be 80MHz or higher.

You cannot make much wrong and you can get one easy for an affordable price. Also like the S3 ISA Cards with S3 801 and 928, which are very fast and where sold with good …

I have a similar build for similar focus (games up to 2004) with a GeForce FX5900 (AGP, vanilla) and i am very satisfied. For your System you will need a PCX variant, unfortunately very rare. Otherwise a Radeon X800 or GF6600/6800 would be good fit, but you loose some DX5/6 features for pre 2000 …

I have the BIOS from an original Spea Mirage P64 VLB with Trio64 without [V] or [+]. You can drive the Trio64 with EDO and FPM - for each you need another config in BIOS. I think the Spea has EDO-RAM.

Thanks for the approval. I have a few ISA cards (OAK, Trident, CL) here besides the Trio64V+ that I would like to add to the test. The GD5434 ISA and VLB are unfortunately also missing in my portfolio. That the ISA variant is the fastest of all ISA cards, I believe gladly. The fact that your values …

I have Trio64V+ too, but no S3 868. The S3 DRAM cards are a little Bit faster in DOS than the S3 VRAM cards. And the Trident 9440 is a very descent card. The Tests were all done in transparent mode.
