OK, not retro, but retro-useful for my Amiga 600:

Now, I've asked a friend of mine with 3D printer to print an internal support to rightly align the floppy emulator inside the retropc.

Everex Viewpoint EV-678 (512 kB, Trident 8800CS "Zymos Poach 51 AA")
I added a copy of the product catalog. I really enjoy reading those old product information flyers.

I just got a package with these nice items.

It was a negotiated trade for a kidney and my left foot...

The sellers picture.

My picture. (No Pentium II Overdrive was included, the manual was a nice bonus though as I already have two new ones but no manual. The filthy keyboard is my own.)

This is what in computer language is known as a stack*.

*The name "stack" for this type of structure comes from the analogy to a set of physical items stacked on top of each other, which makes it easy to take an item off the top of the stack, while getting to an item deeper in the stack may require taking off multiple other items first. -Wikipedia.

Beware of some hidden misperfections, IIRC it was this seller who sold a nearly broken Cx5x86 to Artex recently.
Also what do you mean by Pentium Pro Overdrive? Such thing doesn't exist. If you referred to the original CPU installed in the ASUS Socket 8 MB with an interposer on the seller's pic, then it's what you later named as "stack".

I edited the Pentium Pro overdrive to Pentium II Overdrive, you see the manual in my picture. 😀

I know fully well what every included item is. Thanks for the heads up about selling almost broken items, I will make sure I test stuff before leaving feedback.

His feedback rating is 100% though which is kind of rare so I dont expect any trouble. Perhaps Artex experience was a one-off?

Ah, OK then 😀

Skyscraper: Did the seller claim the ASUS board worked with the Powerleap adapter? Because that board model is mentioned on the Powerleap compatibility page as not working.

I don't think so, but you can perhaps say it was implied. As long as every item by it self work as intended I'm satisfied.

My collection of Socket-8 boards is starting to get quite large so I can pick and choose. 😀

I don't even really care if there is a single Socket-8 board that actually works with the Celeron 1400 (at 933). I can use the Powerleap Neo s370 and Lin-Lin elsewere, I'm not even sure the Neo s370 is needed for Coppermine support as the Coppermine CPUs are on the support list for the PL-ProII, I guess it depends on the version (of course no SMP for Coppermine Celeron). Even if running dual PIII-S 1400@700 would be kind of awesome I feel such CPUs are better used elsewhere. Dual Celeron Mendocino 533 on the other hand...

I do really care about the Powerleap PL-ProII working though and I really want another one... And of course I expect every item in the lot to work as they were sold as "used".

Is that for the Socket 8 systems to have a Pentium 3 installed or equivalent? I've never seen something like that before.

Yea it's a FC-PGA to FC-PGA2 adapter sitting on top of a Socket 370 to FC-PGA adapter sitting on top of a Socket 8 to Socket 370 adapter.

Depending on revision of the Socket 8 to Socket 370 adapter the Socket 370 to FC-PGA adapter might be redundant as I think the later revision of the former was in fact a Socket 8 to FC-PGA adapter. It's not impossible though that Power Leap just slapped on the Neo S370 them selves and declared the PL-ProII FC-PGA ready. 😜

I think the test motherboard will be an Intel Venus VS440FX. The one not in storage is from a Gateway 2000 but if I only find Gateways latest BIOS update it should be compatible according to the list, otherwise I will install Intels BIOS or go on a hunt in my storage units.

What are some prods that actually have compatibility issues with the PnP? I've heard this said before but I've NEVER run into something that didn't work with it. I haven't seen every demo or intro out there but I've been using a PnP since '98 & to me it seems to do the job just fine.

Skyscraper. I'm really looking forward to you sharing your results from the stack testing 😀

I will probably create a thread later 😀

So far I have just checked that the Asus motherboard POSTs, it does. I also checked that the three Socket 8 CPUs included in the bundle works, they do although the Asus board doesn't see the Pentium Pro 1MBs cache, probably just another incompatibility.

I have also checked the Unisem US3004 controller on the Pl-ProII. The version I have supports 1.3V - 3.5V, not 1.8V to 3.5V like the old PL-ProII manual I have states. This was either an undocumented feaure if the "Coppermine version" of the PL-ProII was just the old one with a Neo-S370 slapped on or there is an updated FC-PGA version of the PL-ProII and this is the one I have. The only way to know is to remove the Neo S370 and try without it I guess unless some member has more information. (The Wayback Machine kind of has most Powerleap stuff except for much of the PL-ProII information, I have all utilitys though.)

I'm temted to leave the whole stack intackt as the Lin Lin provides a ZIF socket which is practical, it also makes it possible to use normal heatsinks. I wonder if the old Mendocino Celeron CPUs will run happily in the Lin Lin or not.

I snagged this 32 MB TNT2 Ultra on the cheap. It was listed as a regular TNT2, but the label on the BIOS chip tipped me off to its true identity. 🤣

It arrived with one of the heatsink retention pegs broken, but I was able to replace it and add some fresh heatsink compound in the process. Thankfully the card didn't take any other damage during shipping and works perfectly. I'll post it's new home in a build thread soon. 😀

Came across a 486 motherboard, the owner wants a swap and I am kind of leaning towards doing it though I have no idea what he needs yet; hopefully not something I can't part with.

I'll be getting just the board.

Strange form factor, probably from a slim desktop case as the riser is just one 16-bit and one 8-bit ISA slot apparently (not a deal breaker as it has onboard IO controller and VGA apparently)? Anyone familiar with this board or know what kind of PC it comes from? Is it worth getting? It appears to have a 512K CL-GD5428 (upgradable to 2MB and I have the modules for this job) and butno cache (removed at some point? I have no modules for this and I believe they are exorbitantly expensive to get?). I have quite a few DX2/4 CPUs and EDO RAM to go with this but have no idea how it would run without cache and what kind of case I can fit it into..

A bit newer than my usual collection, but still over a decade old at this point. Got it a few weeks back but didn't really do anything with it until today.

ATI X1900 XT.

Was pretty dusty. I'll clean it properly when I use it or put it on display though. 🤣

No idea what the hell a GF256 GTS is but I bought it anyway. Probably just a GF2 GTS.. But weird as hell.

get off the cooler, and you can see, it is an nv10 or nv15.

It's a GeForce 2 GTS. 😀
