My last repair turned out to be not done yet. The Packard Bell PB430 mainboard didn’t work well, let’s see how PB410 would …

As so many others I was beginning to worry for you. Glad to see you back👍
Danke!
Waiting for a video from you is like waiting for a girl to get ready. It might take some time but when they arrive you forget all about the wait and just enjoy the great moment. Can't wait for what you have in store in the next one!
Wonderful repair work. It honestly looks a little sloppy or cumbersome in magnification, but the final macro shot looks unbelievably tidy. I've resoldered pins to a CPU before and that was bad, but I can't begin to appreciate whether I would have the patience for this work. Great music choice for the montage too 😊
A quick CACHECHK would verify if it's in cache disabled mode
I really really dont want to sound condescending here because you are literally the GOAT of these retro repairs…. But.. My Dell of similar vintage has a BIOS option for boot speed Fast/Slow. Did you check if the PB has similar?
Which dremel tip do you use to file off oxidation?
Long time no seen !! but,I'm glad you made it !! The Value you bring is unmatched in the hardware domaine.
I salute you with respect brother !
Great video!
Sometimes I wish I could do what you do and other times I’m also glad I can not 🤠
Your videos are easy to watch and you make them enjoyable.
Always love seeing your repairs. Your channel name is quite fitting given the kind of stuff you've repaired before. Your trace repairs are always top notch looking.
He's good isn't he? 😁
Awesome video. Your skills are amazing.
Your soldering is a work of art.
Necroware, the king of all cliffhangers! 😀
I had a problem with a TMC PET48PN once, where 2 pins were connected inside a VLB slot. Data line 4 was connected to ground, which caused all sorts of unexpected behavior. One of such was the computer randomly hanging, always seemed to be running in de-turbo mode, but able to enable turbo nonetheless, which made it run even slower.
Eventually, I found the pins inside the slot. I was working on it for months! Rabbit hole anyone!?
Anyhow, thanks for the awesome video. I can’t wait to see the next one. 🙂
Stay safe!
@18:09 That's incredibly neat. I'm doing exactly this repair on an identical board from a Zenith Z-Select 100 3×3 and I know how much patience and practice this takes! Excellent and inspiring 🙂
Hi Necro, nice video and extremely nice soldering. Regarding the speed just check your jumpers. Some of these boards behave weird if you have it set to pentium P24 of smth. Just google PB430 Processor Upgrade. Some boards also used Jumpers for maintenance modes which interupts the cpu. Greetings from Nurnberg.
So good you are back
Great to see you back! Awesome work. It always amazes me just how much damage those batteries can cause. It's also very interesting how various manufacturers implemented the turbo functionality. I had always assumed it was L1 cache being disabled on most 486s and didn't know about the halt signal that some used too.
I've never seen those SIPP video cache memory, it would be interesting to look into that more
So glad to see you have had some time to make a new video. thank you.
Beautiful repair work as usual, it's a shame you couldn't repair the other board in this video, but no doubt you'll get both running perfectly in due time
Thanks for working on this, as I said in a previous comment, I have 2 of these that I need to do these repairs on as well and this is extremely helpful.
I like how you bend the repair wire to follow the shape of the original trace routing instead of a bodge wire just connecting point A to B. Much cleaner and superior attention to detail! Cool video.
I am very happy that you're back, and well, I so love all your content. So do thousands of others.
I'm so glad you're back, I always enjoy your repair videos. Looking forward to the follow up!
Life does indeed happen, but don't ever feel like you need to apologise for it! 🙂
Wow, your trace repair work is amazing, you make it look so easy!
Thank you for repairing that PB410 board. That was my first PC in 1993. Still have fond memories of it. It's also emulated in PCem and 86Box if anyone is interested.
this is just an idea, but what if board needs Turbo LED to be connected to actually switch turbo on/off . led is still a diode.
Welcome back
23:55 "that was one of those wow moments" i bet you were jumping up and down in excitement, shouting "YES YES,YES! its working! Amazing. I can't believe it. Its only gone and bl00dy worked! Yes!
9018 chr/ms!? I've never seen anything much above 6000 on a standard ISA BUS (although anything VLB usually scores in the 5-digits, so this is either an insanely fast ISA card or a pretty slow VLB card)
In my experience, the "newer" Cirrus Logic series (the "older" being not SVGA capable) are faster than most anything, I get between 4000-6000 on these, while the Tseng 4000 scores between 2000-6000. And Headland – well it depends on the MoBo I guess, I got around 3000-4000. Still, in a world, where everyone is craving for a Tseng 4000 or a Cirrus Logic, I happily reach for something odd, like Headland. Or Realtek (it took me 5 years to find working drivers! They aren't compatible with Win3.11/95s generic SVGA drivers). Or heck even Trident. I'm not too happy with the Oaks, they are slow (as are the Tridents), but I kept observing horizontal instability in all resolutions except 800×600 on almost all my Oak cards whereas none of the other cards had that. On 286s, my favorite is Paradise (incidentally, most cheap all-in-one 286 MoBos have Paradise as the on-board (S)VGA card).
Brilliant work!!!
That's what I call a pro repair, ie, wire soldered on the full length of the original trace – saw a bad repair vid today lol –
I wonder if a mini sandblasting gun would be easier, but then again you would probably need a spray can of UV solder mask because it removes a larger area.
