The Antec TP-II 550 is a powerful power supply that was originally offered in two variants: one with the TrueControl panel and one without. The TrueControl panel was a unique feature that mounted in a 5.25" drive bay and provided manual voltage adjustment through four potentiometers (pots) for...

Just wanted to follow up here again that after I got a whole load of CPUs in and started testing them in this board, I realized that I must not have cleaned the socket pins well enough the first time since every time i switched a CPU in, it wouldn't post again. So i took the socket cover off one...

Hey all, just wanted to share my experience reviving my old MSI MS-5169 Super Socket 7 Motherboard. Initially, this had a ton of bad capacitors on it. All were replaced with modern equivalents, but after replacement, there was still no post. Checking the common mosfet failures on these boards...

Just to add sample size here, just had another mx-500 on the bench. This one looked mint inside, but c4 was clearly melty and swollen. Machine was happy as a clam again after replacing it!

@Stephen suggested I long-form this here after my recent repairs. I'm attaching the MX-500 Service Document to this post in case it goes missing, but it's invaluable for troubleshooting this thing! I bought a "for parts" metcal mx-500 on ebay, and sure enough, it mostly didn't work. On initial...

@This Does Not Compute - let me know if you want to try that egret - i'm nearbyish so it'd get to you pretty quickly. That said, @Kai Robinson i wouldn't think the egret would prevent boot though? or does it do more on the color classic than the lc2 and 3? I thought it was just soft power and adb?

@This Does Not Compute - I should have added that, I'm using the same power supply for all the testing 😀 I've updated the original post to include that now 😀

looking for some ideas on an LC2 I'm working on... system will not boot with original roms - it does chime howerver and just hangs at a flat grey screen (not alternating pixes with the mouse). these roms work fine in my lc2 board. with a known good 4th (HH) rom chip installed (341-0746) this...

I ended up making a few iterations until I found one that worked well... if you need it, here it is 😀 https://www.printables.com/model/478097-packard-bell-486-power-switch-connecting-rod#preview

Better than the other direction - had a lc power supply i recapped that was working perfectly for months... set it aside, and came back to it this week, now it's just ticking ☹️ We'll have to open it back up and figure out what's going on with it again...

Hey @jcm-1 maybe a long shot, but check continuity from the positive site of the 1uf 50v cap (c22) to the pin 9 of the sounchip (2nd pin from the back of the board on the side closest to c22). I've had that trace get damaged and it's almost impossible to see, and you'll get no sound. Just one...

Hello All! I'm looking for some help and hoping someone has a Packard Bell case similar to the one below, as it was used in multiple models over the years. Mine is missing the power "rod" that goes from the front of the computer, behind the HDD try to the internal power switch in the power...

Someone on reddit replied to let me know it's a 102 resistor 😀

Hey all, got a working Performa 475 with a pretty rough case, but the machines runs great. Unfortunately, the battery had started just barely corroding and destroyed the trace to resistor R50 on the back of the logic board. In the process of cleaning up the area, the resistor jumped out of my...

I was glad to help out! @Willj did most of the work (I still don't know how to make the gear itself!) but I added the little details on the underside and rounding some of the teeth corners on the upper gear to match the original as closely as possible. Prior to this, I had never seen a Sanwa...
