Nope.

Mostly Deer, Sun Pro, YX-GP (Delux branded), Yuelin, some noname OEM that uses a black PCB (yet the rest of it is worse than anorexic), KeyMouse, CWT ISO and finally an AT Macron from ~1995.

I guess I could post some of the crappy stuff when I have some time. There's a lot of them. There's also a sad 120mm PSU that has its wires cut - I think it might be one of the gutless Zumax but I don't really know.

Apart from that, I managed to save some for myself - a pretty nice Casecom (Sun Pro) unit, the Premier LC-8500BTX mentioned above, and a Frontier LC-8460BTX in which I swapped the guts from a G-Alantic (CWT ISO) unit that had a beaten case but the electronics were fine. I could post a picture of those that I fixed at this moment including that Frontier.

Smile Gateway Select 650 continued (part 2)

Just sorted through the new pictures of the Gateway Select 650.

For those of you not familiar with the Kadoka motherboard, here’s a view or two:



And here is that interesting CPU VRM up close that I was talking about:
https://www.badcaps.net/forum/attach...1&d=1554953251
As mentioned, there are no electrolytic capacitors here or anywhere else on the motherboard – just Tantalum caps and ceramic ones. CPU VRM is 4-phase, high-speed switching, and with soldered heatsinks close to the MOSFET’s Drain tabs – now *that* is a GOOD cooling design.

Next, chipset and LPC SIO:
https://www.badcaps.net/forum/attach...1&d=1554953251

The whole motherboard cleaned up very easily as it wasn’t that dusty. Shame about the broken PCI slot, though. Speaking of which, I just couldn’t leave it there like that, so I removed it:
https://www.badcaps.net/forum/attach...1&d=1554953251
https://www.badcaps.net/forum/attach...1&d=1554953251
https://www.badcaps.net/forum/attach...1&d=1554953251

I suppose loosing one PCI slot is not going to be a big deal, as this mobo had five total before. Four should still be enough for everything I need (audio, LAN, maybe USB2.0… we will see. ) Of course, I do also have a broken (literally, snapped in half) Dell OptiPlex GX260 motherboard that I can pull another PCI slot from. But on that note, does anyone have any tips how to remove slots easily and without damage? I removed the above slot on the Kadoka with my 40W Radio Shack bulb desoldering iron. It was OK on the data lines but struggled on a few of the ground and power lines. Thus, I ended up melting a big ball of solder on one side of the slot pins where that happened in hopes of pulling the slot when I melted the entire solder ball. Unfortunately, that didn’t work so well. The solder fell through the vias instead, cooled, and then made it even harder to try to desolder. So that’s why you can see the pins on the actual connector are pulled out on one side. Does anyone reckon if hot air / a massive bottom heater will work (without melting the slot)? I might try that with the broken OptiPlex GX260 mobo. I also would like to pull the AGP slot out of that one to try putting it on another Dell board that has the holes for it, but no slot… though, that’s for another silly rainy day project.

Anyways, moving on… here is the bare case after I cleaned it:
https://www.badcaps.net/forum/attach...1&d=1554953251
https://www.badcaps.net/forum/attach...1&d=1554953251
https://www.badcaps.net/forum/attach...1&d=1554953251
Finally a case that isn’t rusty! It wasn’t very dusty either. Nice heavy steel too, just the way I like it.

Also, let’s not forget the manufacturing / model sticker:

Made in April 14 of 2000. Ha! Four more days before its 19th birthday!

All the parts that need to go back in the case:
https://www.badcaps.net/forum/attach...1&d=1554953575

But before that, I needed to fix a few things. First, the snapped supporting tabs on the top plastic piece:
https://www.badcaps.net/forum/attach...1&d=1554953575
PVC glue works great on ABS plastic! It just cures a bit too slow. It’s been over a week, and I can still leave an indent on the glue. In some cases, I’ve had it take almost a month to become fully hardened.

This is why I often use hot glue in places where it will work fine. Speaking of which…
https://www.badcaps.net/forum/attach...1&d=1554953575
Just before installing the motherboard in the case, I found that its 3rd USB port was broken and pins inside all mangled up. If it was a dual port, I could have tried replacing it with one from another motherboard. But because this was a single triple USB port, I just un-mangled the pins so that they are not shorting to each other (or the case) and filled it with hot glue. I suppose that is not that big of a loss either, as these are USB 1.1 ports.

After all of this, it was time to put everything back together – and so I did


A shot of the front:

I suppose the only eye-sore is that Philips CD-RW drive. For this reason, I actually removed it before storing the case. I will eventually fix that CD-RW drive too. (Already have glued the plastic bezel together and fixed the broken door mechanism. Now I just need to figure out why it doesn’t work at all – no power… but that’s work for a rainy day/weekend too. )

So, after all of this cleaning and fixing – THE PC WORKS! At first, the PSU fan was a bit grind-y – sounded like a bad bearing on a car alternator or water pump. But as it warmed up, it became quieter. Still, the PSU worked without problems. Voltages were rock stable and what they should be. Leave it to Astec to design a good PSU, of course. Almost all caps inside it are Nichicon. The original CD-ROM and floppy that came with the PC also worked – read through my Windows XP SP2 CD fine. The motherboard also Mem-tested successfully.

The only bits of original hardware that I haven’t tried yet are the LAN and sound card. I’m pretty sure the LAN card will work, as it was somewhat away from the motherboard carnage. But as for the sound card, we will see. That said, I did fix it up a bit, though:
https://www.badcaps.net/forum/attach...1&d=1554953575
The ports still need straightening (not really visible in the picture). But overall, it looks a lot better and actually can be installed in a slot again.

Oh, and I even managed to save the parallel IDE and floppy cables.
Before:
https://www.badcaps.net/forum/attach...1&d=1554953575

After:
https://www.badcaps.net/forum/attach...1&d=1554953575
On the IDE cable, I just cut the “ugly cut” it had. And for the floppy cable, I did the same and simply re-installed the end connector. I suppose that is one nice thing about parallel drive cables – they can be fixed (and shortened), if needed.

So there you go, folks – another old PC saved from the dump. I really have no idea what I will do with this one. But the plastics are in near mint condition – no yellowing and hardly any scratches on the outside. It looks many times better than my Select 750, which is all dinged up, a bit yellowed, and is even missing the plastic for the power button (to turn it on, I have to stick my finger in a hole on the front bezel to press the little button behind it ) Thus, at the very least, this could make a really decent-looking retro PC.

the eyesore is the windows sticker.
and stickers on light cases are bad anyway - when they eventually peel the case will be a different shade.

wow, someone did a number on that PCI slot! Very nice rebuild though. anything old & beige always has a place in my heart. Are you going to replace that PCI slot or just leave it vacant?

Tek TDS754D in good condition dropped off this morning. No probes (of course! :< ). These things have been falling out of the trees, lately (I think this is the fourth one I've received).

I'll check to make sure the attenuator board is intact and, if so, upgrade it (bandwidth plus "options") and give it a quick calibration before passing it off to the local "Maker" house.

Default Re: best cheap/free scores 1.1

Got some really good deals of the last couple of weeks.

Yesterday
  • Macbook Pro Early 2015 i5 2.9Ghz / 8GB / 512GB SSD - £60
Backlite wasnt working, checked fuse which was good. But in the process of taking it apart and cleaning some connectors its all working it seems. Dont want to get too excited just yet as has only been an hour or so, will see over the next few days. Runied the pentolope screws whilst opening thinking they were star screws but cheap enough on ebay.
  • Mitutoyo 293 micrometer - £10
Super accurate and pricy, measure a piece of paper down to the micron. impressed
  • Xbox One console only - £20
Seems to be working fine

Last week
  • Got 2 x HP 8470P Laptop - i5 3320M / 4GB RAM / 120GB SSD - £10 each
Seller had 8 of these, kicking myself for not buying them all but was thinking i should limit risk. Even for parts would have been worth more. Anyhow had to order power supplies but both working fine.


Loads of other dtuff but the above were the standouts.

Bought a Core i3 3220 for $19. Was worth the upgrade from a Pentium G645.
