Recap job doesn’t look good on the IIci. Never was a fan of using through hole parts in a SM application. If it works, it works, but consider redoing it with surface mount polymer or tantalum caps. Nice portrait display, uncommon find!

Picked up a custom made G4 accelerator off of eBay. Someone is doing these as a hobby and selling small volumes of accelerators. It's a modded Apple 800mhz board with a 7455 chip soldered on and the required mods to set the clock to 1.5ghz. Paid $150 on eBay, works great. Scores 857 on...

If it’s hot, it’s probably not an L88M and it’s a reseller fake with the original markings wiped off the top.

Well, it isn't a Performa 630. It's a 6320CD. No idea how this happened, somehow the seller wrote "Performa 630", the photos showed a Performa 630, but the computer front panel says 6320 and the logic board is a 6320. The serial number matches what was in the listing. Totally confused. The...

The front case is labeled Permafrost 630CD, so I assume this wasn't a 62/63xx case swap. Exited to have it and take a look inside.

I bought a Performa 630CD on a whim off of eBay. The price was low ($70 total) and the case looks immaculate. Why? The manufacturing date on the back is oddly late for a 68k, 6/20/1996!  Deep into the reign of Gil Amelio and the PowerPC era. Was it an oddball product of clearing old inventory...

Probably need to replace capacitors, start with the axial ones that are deeply involved with power delivery on the motherboard.

I'm interested in a set of 4 - still possible?

Glad you found that tidbit potentially useful. The cooling design of the 6100 is barely sufficient. Once you add a hot card (486DX2 or a G3/G4) it will cross the thermal threshold under load. Age has made these less stable, with leaky caps. I recapped mine and it's now super stable. 6100 is a...

The IIfx is a wonderful machine, hope you will get many years of enjoyment from it! You lucked out as your board is 100% SMD Tantalum. Most IIfx boards have two of those cursed cans in the upper right corner by the PRAM batteries. Nice Radius vidcard with the photobooster. I have a similar card...

Apple used Maxell from the factory, and they leak acid in an explosive fashion. Fresh PRAM is a very good idea to preserve the system regardless of battery make.

!!! Is that PRAM battery a Maxell? If so remove it ASAP. The red color drew my attention. Those leak and destroy the logic board. congrats on getting the SCSI2SD going

I had the same thing happen recapping my 6100, just a single dry joint with minimal solder not actually making a solid connection.  always feels good when something broken comes back to life!

The Apple custom ASIC to the left of the Zilog serial controller might be a goner, but fingers crossed you can save this system!

I would think the slightly higher voltage would be OK if you load the system up with expansion cards. The IIfx PSU barely cuts it when you have tons of high power cards installed. .10 over is within tolerances, although kind of on the hot side. Monitor ASIC temps and make sure no chips are...

Did you try cleaning the contacts on the board? I would get a can of electric contact cleaner from an auto parts store and clean every slot on the board. I've had weird issues like yours go away from that treatment.

Just sharing a neat thing I ran into today working on my 6100. PCI slot blower fans fit perfectly under the HDD cage without any Velcro. It's a snug fit so the fan will not move. This drastically improves airflow in the system, blowing cool air over the 601, Cache, and PDS expansion card. I...

Idea: Contact Cleaner.  CRC QD from an auto parts store works wonders. I have had that stuff fix inexplicable problems. Spray down the RAM SIMM slots, ROM slot, and cache slot. Heck, just bathe the whole board in the stuff, it evaporates.

NoofleBot, I have a spare IIfx logic board, I keep it in case my IIfx has a catastrophic failure. I highly doubt it will die out of the blue though, as I recapped my main IIfx logic board last year and now it is rock solid reliable. I'd be willing to sell the board to you, if your a collector...

I just did further testing. Pulled out the 7100/80 I will refurb for sale and thought to give it a try. The G4 card fired up in the 7100/80! ;-D I need to pick up a can of CRC QD contact cleaner and blast the PDS slot of the 7100/66. Next to test is the dead G3 one. All three of my...
