Note that OP asked about the equivalent of a Core Duo, not a Core 2 Duo. That lowers the bar somewhat, but is still far more than this platform could handle. Basically the Core Duo delivered about the same performance as the Athlon64 X2, clock-for-clock. That said, OP, could you clarify what you …

Out of interest - what is the added value of DDMA if the only chipsets supporting it are ones supporting regular ISA anyway? that's not true, for example VT82C686 has close to excellent DDMA support and there are many motherboards with that chipset without any ISA slots. also, some PCI cards have …

If you have them... My multi-sound card system has a GUS Classic, PAS16, MusicQuest and either a CT3670 'SB32' (i.e. AWE64 with SIMMs) or an Aztech NXPro (for SBPro2 and Covox-suppot). Havent been able to get the NXPro and SB32 to work together though, which would complete this build. But this is …

VT823x on an ApolloPro133A? Nope, this is a DFI TA-64, pairing the 694X with an old 596B. that one i believe doesn't support DDMA, but I am not sure, because 596 was intended as laptop chipset. So, I believe it has only PC-PCI/SBLink support (as that was used for a docking station with ISA slots …

That Jazz16 chipset isn't PAS or PAS16 compatible. Hmm, PAS compatibility would be my main reason to pick this card. Reading about it and seeing the issues it has with Windows compatibility and DB headers I would choose the AZT2320 instead if accurate OPL3 is your thing. The Jazz cards were a very …

If it's FM synth you're after, you want OPL3 or the closest possible clone. Listing those cards: 1+2) Jazz16 and Aztech AZT2320 - both have a real licensed OPL3 3) ES1868F - ESFM isn't the real thing, but close. 4) AWE64 - CQM isn't bad, but it's not OPL. As a GUS owner I'd also thoroughly suggest …

This is seriously interesting stuff. Too late this evening to get started, but I have at least one and possibly two or three CMI8738 cards. I'll dig them up tomorrow and see about the chip revision. Would be very willing to help test, but complete novice on the software hacking side, so will need a …

Here we go again... There's an FCC ID clearly visible in your second photograph, have you gone to fcc.gov to search for what that tells you? There are RAM eight chips with chip codes clearly visible. Googling them gives you information on capacity (and other specs) The BIOS chip seems to have a …

Indeed, you can get Northwood CPUs for (near) free as well, and AthlonXPs too. Both would be a far easier, more natural choice for the V5, cheaper too as you can take pretty much any universal motherboard, and it's unlikely the Prescott would be faster.

The SIMM is itself is just a piece of PCB, so long as the traces are good it's not relevant for performance or compatibility - it's the chips that determine that. No idea as to the brands. So yes, if both have 16 4Mx4 chips on them, they are both double-sided 32MB SIMMs (note: "double-sided' doesn't …

The SIMMs are completely different, but if they have the same humber of the same chips they will work the same way. You've only photographed one side, but both have 8 km44c4104ck-6 4Mx4 16Mbit chips on them. That's 16MB on one side. If there are 8 identical chips on the other side, they'll be 32MB …
