Picked up this red hot 🔥 beast Ti4600 Golden Sample recently. Anyone know to get the three pin power connector to work?? The original cooler works just fine, but I'm not getting any power from the three pin connector. Maybe it's a software switch or something?

Huh, did you know a full schematic for the NV25 P80 (Geforce 4 Ti4600) board is available online?

So it's actually the connector for the stereo vision goggles:

Good catch. And it makes sense. At that time GPUs generally didn't have any fan monitoring so they pretty much universally had 2pin fan connectors like the one along the bottom edge of the board. Just a simple power and ground.

In fact, I don't think it was until the Geforce 7000 series that we started to see more than two pin fan headers on nvidia GPUs.

The other is a switch (HUB?), with the possibility of connecting 10 100 and even 1000 LANs, therefore almost all PCs, lack the power supply, but you can easily find one of the same voltage (5V), at the moment I won't be able to verify this, but maybe it could be useful if you wanted to connect more than one PC.

If it supports 1000Mbps, it can't be a hub, as GbE is obligatory full duplex, which cannot be run over a hub.

This just looks like a generic unmanaged 5-port Gb switch. It could be something more exotic though, I have a similar-looking D-Link PoE passthrough switch, that can be powered by PoE and pass it through to one more device. Oh, and it's managed too. But check the type. As a rule, almost all Gb-capable switches will support 10Mbps, so should be fine for vintage stuff. I have mine networked via a Netgear GS116E, also a Gb switch, which plays nice with everything down to 10MbE cards in an XT.

Recently picked up a Thrustmaster Combat Gear set. The box was opened, but it looks like it's new old stock. The set comes with a "Top Gun" joystick and an "Attack" throttle. Too bad it didn't come with pedals.

The joystick is fairly small, but it feels well built. It feels a lot stiffer than any other joystick I own, which I prefer. It also has a rubber part where the joystick meets the base, which feels like it could inhibit the range of motion a bit. It's hard to describe, but you have to use a bit more force to move the joystick at the ends of the axes. It doesn't really have an abrupt limit at the end of the range like other joysticks I own. Rather, the rubber starts compressing at the ends and you have to push harder into the rubber to make it move a little further. I haven't plugged it in yet, so I don't know if this would be a problem and if it could be addressed by calibrating the joystick with a less extreme range of motion.

There's not much to say about the throttle, except that it feels a little more plasticky than the joystick. Not a big deal to me though.

The set also comes with Eidos's Joint Strike Fighter. I'm more into WWII flight sims, so I've never played it. Interestingly, I read in a review https://www.combatsim.com/review.php?id=317 that it was made by a demoscene group who developed an advanced terrain rendering technique.

The rubber might have hardened over the years. The feel might not be as it was when it was new.

Good point. Might just have to break it in a bit.

Paid $95 in exchange for the SC-88PRO, AC230V input, no need to modify the power supply unit, it will be added to my MIDI tower.

I've read that it's possible to rejuvenate certain kinds of rubber by boiling them as well.

There seem to be a lot of methods out there.

I would try the less noxious or destructive ones first myself. 😀

Warm soapy water, vegetable oil, etc....

Very nice! Don’t forget to replace the battery or remove it all together.

yeah would have been had the scrap guy not destroyed it by ripping the IO off.

Got this ET6000 4MB (Jaton Video Magic 128) for a very late 486 build.

If you do boil it, use something to lift it off the bottom of the pot so that it's heated by the water and not conducting the element at the very bottom.

Thank you for the great information!! Quite the bummer as it looks like it was built for that aftermarket G4 cooler. .. oh well.. back to stock it is i guess.

Cheers!

Sorry, but unfortunately I'm quite ignorant on the subject, then add the translation, the result is not always understandable.
I add a couple of images, I hope you understand more, I noticed that it has 8 ports and not 5, it could be an advantage, and maybe some of those 8 could be used for peripherals, i.e. printer or other.
Considering that the price was 0 (gift), I am interested if it can be used in some way, I hope you can advise me on how to use it, thank you very much for the suggestions, and if you have the desire and time, you can look at my page, the repairs and tests on several MBs, I hope I don't bore you, and if you want to participate, you are welcome.

Just redo the 3-wire fan to 2-wire. You just need red and black. The yellow if for the tach which is not necessary.

Re: Test and troubleshoot PC@LIVE motherboards

Your photo shows the model number of the switch: DGS-1100-08

So it's a D-Link DGS-1100-08 Gigabit Smart Managed Switch

It is very likely to be useful for you as a networks switch:
- It's an 8-port Gb switch, so you can use it to connect up to 7 devices to one network cable
- it supports speeds up to 1Gbps but also down to 10Mbps, so both your modern system(s) and vintage stuff will work

If you're not into networking that should be enough, but as it's a managed switch you can do a lot more if you want to explore:
- set a mirror port to capture all traffic to and from a device, for security or troubleshooting
- set up VLANs to segment your network (useful for keeping insecure older computers off the internet, or guests/siblings away from your systems)
- set up QoS to prioritize certain traffic on your network

You can find more information/documentation here:
