This Gigabyte board has a self-destruct feature where a voltage regulator fries any caps nearby. Hopefully a perfect pair for the gorb after recapping.

The GA-BX2000, love it, have some sentiment especially for the Dual Boot logo on startup.
Could you say more about its design issue? I have one of them dead and I wonder if replacing all the caps will fix it immediately or I need to replace something else.

I'm no EE, but component placement + no-name Stone caps seems stupid. That's one certain point of failure. Also the attachment of that orange heatsink is really sketchy. There's a thread on badacaps.

I've yet to perform a smoke test.

I believe this is due to excessive AGP voltage, mostly caused by Voodoo 3 cards?

I’ve scored Powerleap PL-K6-III v. 2.0 interposer. Still didn’t have time to test it but hope it will allow me to sport K6-2 or even K6-III in my Socket 7 Olivetti. However, one thing is intriguing me, why this interposer does not have small heatsink with VRM at the back as I use to see on the other interposers?

Nice score! Congrats.
The VRM is a switching design that will output much less heat than a linear regulator so it doesn't require a heatsink. Putting the switching transistors inside the socket saves space but prevents air movement over them so maybe that's a bit suboptimal. With good cooling on the CPU I wouldn't worry too much though.

Very plausible, the Voodoo jumper on this board hasn't been shorted. The board and cpu fans turn on but I get no post beeps or video.

Yep I’m really happy to have it, especially because I don’t see much of these interposers around. Also thank you for the advice, I will put special attention to the cooling. Just using the occasion, any idea what I have to set on the motherboard in terms of the multiplier etc.? I’ve read couple sites already and the manual itself but they just describe how to use the dip switch on the interposer itself. Is the interposer somehow „overwrites” the settings on the mobo?

If you have multiplier or CPU core voltage jumpers on the interposer the corresponding motherboard jumpers should be ignored.

Awesome pickup! I'm surprised these haven't been reverse engineered.

In principle it's simple to make a new design but doing so is chore. Also CPU sockets [Edit: currently readily avaliable again] and the interposer pins are hard to source so I don't think it makes too much sense to just release a PCB design for individuals to order and assemble themselves.

The parts are all readily available to order, it isn't an exotic design and uses common parts. It is just that nobody has taken the time to clone it. I'm currently building a 68040 to 68060 interposer board and sourcing the parts took all of 5 minutes on Mouser and Ebay. Socket 7 PGA sockets are even more common than that. Although it would probably be better to design the top socket on a SS7 interposer with a ZIF socket so you could easily add a nice heatsink. (those are about $5)

Yep it has dip switch underneath. Thanks for the answers, can wait to play with it this weekend 😁

Right? I also had such thought first, but then I realized that maybe a lot of ppl would just rather buy Socket 7 board that directly supports K6 processor of choice. It would be seems like a easier and cheaper solution I think, but on the other hand our hobby is not always about choosing easier and cheaper way 😁

Bought this nice 386 minitower for $40 from ewaste:

Shuttle HOT-307
20mb ram
MediaVision Jazz card + Panasonic interface CD
2mb Diamond Speedstar64 ISA

Very happy to get the Speedstar64 in particular again 😀

Also found 3 random Biostar Socket 7 motherboard boxes lying around in an ewaste bin, turns out that they had a nice group of completely different contents. They must have upgraded a few computers back then and stored the parts for years:

PCChips M919 V1.5

Both PCChips boards have Am5x86s installed as well.

Nice finds I wish I could find stuff like that by me but sadly there's no ewaste places anywhere near me and for the 6 years I've owned my house I've yet to see any computers or come to think of it any electronics out to the curb for garbage either.

Same here 🙁 However I simply don't have the room for everything I'd save 😁

Found this strange card in a junk lot with a bunch of basic video cards. I've got a soft spot for Frankenstein esque cards like this. I don't expect it to be anything special, but if I'm ever doing a build and I have to choose between scsi and pci video, I now have a perfect solution.

^.^

It is a mistake to think you can solve any major problems just with potatoes.

In New Jersey? There has to be.

edit: a quick search shows these are some places. There are bound to be a lot more since this was just the top search result. You have to contact these places and offer to buy things (for more than they get as a per pound recycling profit - don't worry it's cheap) once any hard drives or personal data is removed. Not all places will agree, but some will. It really helps if you know someone or a friend of a friend/family works there. The best place I've found is when cities do drop-offs in a specific location -- usually once a year. Most are just an unsupervised 40yd open ended dumpster that people set stuff in. Local dumps also have an electronics recycling section -- some allow taking stuff, some don't.

Ah, if that's the case you need to actively seek out these types of things. You can't really expect anything to fall in your lap -- I've only had that happen one or two times out of many years. Most components that myself and others get are actively looked for. Sometimes it takes a lot of driving to get a good deal or even free item. Several times per week I'm checking various places, and come up empty handed. Every once in a while it pays off.
