Recently I learned on this board that PCI and, to a lesser extent, AGP cards are getting harder to get by. So I bought a lot. And there was a lot in this lot. Call it the mother lode. Anyway, now is the time to decide what to do with each item. The choices are:
-keep, if it's an upgrade for my XP PC (P4/Audigy 2 ZS/HD6850) or W98 DX7 PC (P3 1000/Audigy 2/Ti4200).
-Sell, in which case I'll best know if any of these cards are particularly sought after/valuable or if they have a good use case.
-Final option: I still have a P3 667 motherboard with ISA, PCI and AGP ports which I'll complete with a graphics and sound card before selling, so looking for suitable cards to put in there (goal is a nice retro rocket, preferably W98 compatible).
-Also tell me if I misidentify something. All those AGP variants, and then there are PCI variants... I don't need to know the detailed name, just if it's indeed PCI/AGP.

A pair of PCI S3 Trio64V+.

A pair of Matrox Millennium II. A 703-00 Rev A and a 708-01 Rev A. These seem to be quite sought after?

Three Geforce 2 MX-200 32MB AGP in packaging.

A bunch of AGP VGA-only cards. nVidia Vanta 16, Ati Rage Pro Turbo AGP, the Matrox MGA Millennium 2 with a daughterboard was for a Dell, a Diamond Viper V550 16mb AGP, ACER AOPEN PA740D.

A bunch of VGA cards with also composite and/or S-video out. DIAMOND FIRE GL 1000 PRO AGP ATX 8 MB, nVidia GeForce FX5200 128MB AGP, MX440, nvidia Riva TNT 2.

AGP cards with VGA + DVI, and one with 2x VGA. Medion Geforce 4 MX460 64mb, Abit Siluro FX5200DT Nvidia GeForce FX5200 128MB (looking quite a bit more spectacular than the Diamond in the previous pic), Asus V9520 128MB, RADEON 9200 SE 128MB R92LE, yet another FX5200 128.

An Audigy 2 ZS. As my PC's use an Audigy 2 ZS and Audigy 2 respectively (each with their breakout box), I think it's smart to just keep this one as an (untested...) spare? Or perhaps a good candidate for in the mentioned P3 mobo.

Hercules Muse LT sound card with CD. "Plays Windows Media"! With gameport. PCI. Nothing special?

Two PCI Conexant modem with mic/speaker connector. Do these act as sound cards or is it phone use only? Can they be used as relevant network card in a retro PC or are they useless for that?

Creative Labs CT4810 SoundBlaster 128 OEM PCI. Good one for the P3 mobo or rather the Audigy?

PCI parallel port. PCI TV card. Are these TV cards of any use today?

3x PS/2 ball mice. I have a lot of truly PS/2 compatible USB optical mice and a PS/2 optical mouse, so I think I'll only keep one of these ball mice in stock. The Microsoft one? Both the MS and the Logi are quite yellowed.

Software, a lot of it unrelated to the hardware. A W95 OEM. Not sure if the CD belongs to the booklet, which is quite relevant for knowing the CD key. AWE32 and AWE64 CD's. CD for the PCI Millennium II, nice. Two Diamond CD's. I have no idea what hardware one of them is for? The other one says "Trio" but the Trio cards are S3, not Diamond?
