  1. Nice find on the Sun Blade 2000. It’s one of my favorite Sun systems and one of the final true workstations before everything started going commodity parts. The CPU cards are very sensitive to how torqued the screws are - make sure to use the Sun supplied torque screwdriver! Sometimes these cpu cards get loose which will cause the system to not boot or behave erratically. There are interesting cards available for the Blade 2000. SunPCi III, Sun XVR-1000 GPU. Best OS for it is Solaris 10. It runs well.
  2. Very nice find! The Am29000 based Apple graphics is a hard nubus card to find. I've been looking for a long time, basically gave up when the last one on eBay went for astronomical prices. Supposedly that card works best in a IIfx. The aviation-grade case is awesome. Don't change it. I really like the breakers they added on the power input. Any of the old data collection software left on the HDD? I'm assuming they were wiped.
  3. It looks like it's mounted just like the original CPU into the pin socket. Pull it out evenly to not bend the pins on the bottom of the card.
  4. 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!
  5. 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 Geekbench. The system is reading the CPU as a "133mhz" G4 but it's clearly running at full speed when benchmarked. Very happy. Only minor issue is the new heatsink bumps into the back of the superdrive, so I took out the superdrive. Anyone know of any shorter depth drives that would clear this heatsink? It can'

    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 seller seems to be as well. I don't mind it that much, I think I have a random Q630 logic board somewhere. But completely crushed the 96 630 isn't really a thing. Weird thing is there is a P630 with plastic just as good as this 6320, supposedly. So, performance of the "P

    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? Possibly. A refurb? Also possible. The fact that the case was common to the 6200/6300 probably made it even easier to keep putting out 630's for those customers that demanded a 68k. It's possible Apple just had a huge overstock of 630/640 logic boards and used up the stock rather than taking a write off.
  10. Probably need to replace capacitors, start with the axial ones that are deeply involved with power delivery on the motherboard.
  11. 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 good machine but it isn't perfect. It's a representative pizza box system of 1994, along with the SPARCStation 4/5 and SGI Indy. All of these had their benefits and their target markets. I'd say a 6100 is most fun with the PC Compat card. Otherwise it makes a good 93/94 era Mac gaming machine.
  12. 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 but with a separate Photobooster on its own Nubus card.
  13. 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.
  14. !!! 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
  15. 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!
  16. The Apple custom ASIC to the left of the Zilog serial controller might be a goner, but fingers crossed you can save this system!
  17. 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 burning hot.
  18. 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.
  19. 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 think this would be a valuable way of extending the service life of these machines. These 601 chips get hot. If you throw in a Houdini 486 card the system becomes an absolute inferno. More cool air should stop the chips from cooking themselves to death.
  20. 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.
  21. 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 and not a re-seller. The IIfx is my favorite Macintosh and I'd like to see the spare board go to someone who truly enjoys this system as well. It's better the spare logic board restore a dead system than sit in my office closet for eternity. I am about to recap that spare logic board, so if you do ch
  22. 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! 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 NewerTech G3 cards work in my 7100/66. Went ahead and applied fresh thermal paste to all of these.
  23. Ran into some interesting problems testing the cards in my collection. My plan was to sell the excess and hold onto 1 or 2 of the cards max. Sadly, the card I wanted to keep isn't working, it's a G4 equipped one. Unlike the usual L2 fault situation where the OS hangs when the Sonnet extension loads, the Sonnet extension fails to recognize the accelerator and presents an X over the extension. I tried cleaning the PDS contacts to no avail. The other card has the usual L2 Cache failure symptom with the hang at extension load time. The one with the failed L2 symptoms has no stickers on the back PC
  24. My 1995 7100/80 has started to have its caps leak after being in storage for years in a semi parts state. Oddly my older 1994 7100/66 hasn’t leaked yet, nor have my collection of HPV and AV cards. These early PPCs are a pain to recap. So many SMT electrolytics were used by Apple to cut costs instead of the Tantalums commonly used on the Q800/650 and Q950. Usually the higher end machines got tantalums but right around the Q840 launch that changed.
