  1. There is some info on adding a 3.3v regulator there: https://powercc.org/takky/
  2. So picked this 68040 upgrade card up on eBay BIN (with an Dayna PDS Ethernet card) for $61 shipped: Anyone know anything about these? Applied Engineering Transwarp/TW 6400 from 1993. Looks like it’s 33MHz, didn’t have a pic of the other side, wonder if there is an optional cache module? Googling doesn’t really turn up much, info or driver wise....
  3. What specific version of Glider are you using? I can pull my “CC+” out and test (I think the 25 vs. 33Mhz speed is they only real difference). Could be cap goo, I used a lot of flux remover (IPA plus solvents) and dental brushes on mine after recapping. Have you ever tried “Apple Personal Diagnostics”. It can do a sound checks, runs through, mono and stereo tests as I recall. I usually run it in a loop after a recap (just on logic board tests) for a while to make sure the board looks good, the system doesn’t crash.
  4. I have a CC with a LC520 motherboard, I hadn’t noticed any sound issues but haven’t tried those games. Does the audio sound okay in the problem games using the rear headphone jack?
  5. I think I do! That looks like the SCSI cable for an external Sony CD-ROM “Discman”. Sony PRD-250 CD-ROM Discman Portable Player (4x speed) https://docs.sony.com/release/PRD250MC.pdf or Sony PRD-650 CD-ROM Discman Portable Player (6x speed) https://docs.sony.com/release/PRD650MC.pdf You can commonly find the drives on eBay but that cable not so much since it only came with Mac “version” (the PC one came with a different cable and PCMCIA card, but it’s the same drive).
  6. Just posted on that, silver lining on the weekend!
  7. With the Centris 610 down for the count I gave the QuadDoubler a try in my 605. ...and it booted just fine, 50MHz! Things seemed good and then after 15 min or so, crash. Overheating likely since it’s probably only meant to run at 40Mhz (2x20Mhz speed of the C610). As a test I moved the case fan on top of the heat sync and it seems stable now. I’d need to figure out a better solution make this work longer term (be able to close the case). But oh so snappy! Benchmarks:
  8. I found a Centris 610 on eBay that looked to have something interesting inside, a Sonnet QuadDoubler. I jumped on it just for the QuadDoubler, thinking it might be a great upgrade for my 605 or 700. I hadn’t looked at/thought about these case style Macs much but they are actually somewhat interesting on their own. I just wish they had soft power, I guess I give the 605 a pass due to its smaller size? True to the description it wouldn’t boot, start up chimes followed by death chimes. I spent the a bunch of the weekend cleaning up the motherboard, re-sold
  9. Well dang. Like yours mine is unchanged after putting the new caps on this morning. Tried 1 (just my RAM & VRAM) and 3 unsuccessfully. I have not done a deep/submerged clean of the board, I guess it’s possible there is still some goo somewhere causing a short...
  10. Small world on here, I’m working on a Centris 610 with the exact same issue right now! Today I removed the old caps and spent a lot of time fixing (I hope..) a couple chips near caps where they the cap goo seemed to have corroded a few legs on two chips (RP3 & IOSB) from making contact with the board. I recently got a nice Amscope microscope which I don’t think I could done this work without. I guess I really shouldn’t count my chickens before they hatch though considering your ( @Byrd and @soviet) experiences. Fingers crossed.
  11. I did not as I was able to obtain a parts machine to steal the back light from. As I recall It did look like there was a good chance that that company could make one that could fit...
  12. For those wanting to try something short of surface mount desoldering. I've had very good luck repeatedly spraying with flux remover (its stronger than plain IPA for dissolving gunk) and using a dental brush to clean the gunk out from under these chips. Got a Color Classic motherboard working this way (also did its sound chip like this). 4140A Flux Remover for PC Boards https://www.amazon.com/gp/product/B07XDCRLR6/ DenTek Slim Brush Interdental Cleaners https://www.amazon.com/gp/product/B009MHV3VW These brushes can actually fit between the chip and
  13. Very impressive! Definitely interested in your BOM as well as thoughts from others on possible 3D printed cases. It would be very cool if there were a guide, instructions, a kit or a product for those of us that wanted a moDern solution to running these PowerBooks off battery.
  14. The linked mouser project looks good to me too.
  15. Your welcome! Your ask for a double check was a good idea cause I made a mistake on one of the tantalums... IIsi Power Supply (Sony) - Daughter Card: Qty x Cap µf x Cap V - Cap Type :: Mouser part # - Case Size Code 1 x 3.3µF x 35V - SMT :: Mouser 581-TAJB335K035SNJ - Size B 1 x 100µf x 6.3V - SMT :: Mouser 581-TAJC107K006R - Size C 1 x 33µf x 25V - SMT :: Mouser 581-TAJC336K025RNJ - Size C <-- the correct one I copied the wrong line when I was making that list, the 3.3µF x 35V part is one I ordered to recap my PowerBook 100 LCD...
