  1. So far so good... I ran gzip -9 on /dev/random for like 5 minutes and it didn't shut itself off so now I'm confident enough to start putting it back together.
  2. Hi! I just got this Quicksilver G4 with 1GB ram and 1.4GHz CPU upgrade and it seems to work in OS9 but under OSX it will just power off after a few minutes. First time it happened when it restarted one of the 3 hard drives died. I removed it and installed a clean OS9 and it seems to boot up fine and not power itself off, Tiger will cause a power off within a few minutes of starting the installer. The CPU fans are running so it shouldn't be thermal protection kicking in. I haven't touched PPC hardware in a while and this is my first "real" G4 so I'm not quite sure where to start. Power could be an issue, I do have 2 hdds installed along with the dvd drive and the only keyboard I have is this OMGRGBLED keyboard so maybe it's just too much power used... On the other hand it did it when booted by usb instead of cd as well. Memory I have no idea how to test since the tools seem to require osx to be installed in the first place. Any thoughts would be appreciated for $40CAD I have no regrets :P e: 12v and 5v rails seem to be fine.
  3. Will do. Had to defer to my dad on the soldering so it'll be a few days before I get it back. While I managed to get the caps soldered in the joints were messy and my hands are just too unstable to fix it. I figured it was best to quit while I was ahead and before I ended up doing some damage somewhere. At least it gives me time to get the rest of the case cleaned up.

  5. Actually it looks like I'm just going to be replacing those. My hands are just too shaky and I'll be lucky to finish even them. e: c10 : 16v 2200uF c13 : 6.3v 2200uF c16 : 6.3v 2200uF c21 : 10v 3300uF
  6. The one closest to the vent holes has certainly popped it's top. It's just a question of whether I replace just those output filter caps or whatever I can find.
  7. Why hello there... So is the procedure to just replace all of them or just a few?
  8. I have to clean my workbench before embarking on either the ATX conversion or taking the PSU apart and today is just one of those days lol... Kinda sucks because I REALLY wanted to play with this G4 for a while, maybe get a decent video card in it at some point. When I do I'll be sure to take lots of pics and such.
  9. When I first got it the PRAM battery was in backwards. Leopard installed but kept powering off during that intro movie, finally got passed it by leaving the battery out for 10mins and leaving the case door open. The CPU got fairly hot when closed so maybe that missing fan is an issue as well, I'll have to jury rig something up somehow. Lending evidence to the PSU issue is the fact that the main speaker is very "clicky" and produces kind of noisy output. Maybe a simple recap is all that's needed or is there something that brings the PSUs beyond user serviceable?
  10. I've done a few resets before and I can try that again. I did end up repasting it and it worked for MUCH longer almost finishing the OSX install before shutting off again. The old paste was dry and crumbly so I applied fresh Arctic MX4 and put it all back together, I was super excited to see it finish CD1 of the Tiger install but it seemed to get stuck on the BSD subsystem then died. Is there any way to find the shutdown reason in a log somewhere? Or check the temperature? e: AHA! ApplePMU::PMU FORCED SHUTDOWN, CAUSE = -122
  11. Found it: http://web.archive.org/web/20081221044555/http://fastmac.com/downloads/newagpinstall.pdf Everything lines up and seems to be configured correctly so this is a Fastmac CPU card and not a Gigadesigns one. The heatsink is on there pretty firm so I don't know about repasting it or even if it's overheating and causing the shutdowns.
  12. Even weirder stuff: I scratched off the warranty stickers to reveal a model name that doesn't seem to exist anywhere: PT55 AGP copyrighted 2006. Under another sticker is a set of dip switches that are likely used to select the CPU voltage but there are only 4 positions instead of 5 like the gigadesign board. Weird stuff.
  13. Dang edit window passed... This looks like it might be a gigadesign card? https://sites.google.com/site/overclockmac/g4gigadesigns looks similar or maybe is a clone? If that's the case then the CPU may be configured wrong according to those switches: 10011 Doesn't have an entry in that table for a 133MHz bus speed so maybe that is related? Anyway I'm scared to plug this thing back in until I know what to do about that pin and I reapply thermal paste. (if I can) e: Straightened it out with a tiny tweezers but it looks like a tiny bit of it has been lopped off, damnit why didn't I look for the proper tools?!!!!! I should have started WITH THE TWEEZERS. Unless that part of the pin broke off in the CPU socket. Is this thing going to be okay or did I just eff up majorly?
  14. I tried unplugging every drive except the hard drive I want to install OSX to but still had the same result. I wonder if maybe this CPU upgrade requires some kind of patch to be installed to NVRAM or something? Thing is there's no markings on it that lead anywhere so I don't know which it is. e: Took the CPU out to check thermal paste aaaand I bent one of the pins I straightened it with an xacto knife but I don't know... aaaaaaaaa Looks like maybe it needs to be straightened more with a needlenose pliers? ...Anyway I got the CPU off but the heatsink seems to be cemented on or something so it won't budge and there are still no identifying markings on the CPU.
  15. I've tried it with one of each 512MB module with the same result. I'll try it with some rando sdram I have kicking around but this is unlikely the cause e: No luck, found a 256MB PC133 stick lying around and it did the same thing. OSX Gets part way through the install or even just sits there then power off.
  16. Didn't see anything too bad aside from mountains of dust. https://i.imgur.com/jmwvNPz.jpg https://i.imgur.com/KkZLIos.jpg https://i.imgur.com/FRL2vMP.jpg https://i.imgur.com/eXytVsc.jpg https://i.imgur.com/kcb5bW9.jpg

    Bad power supply or bad luck?

    Can you still boot using a CD to check/mount the hard drive or did it get fried? AFAIK There are a few reasons a backlight can fail so you'd need to open it up and check the fuses and such. I'm not 100% sure about checking the inverter, my dad would take an AM radio up to such things and see if you could hear the power supply oscillating, might be something to check out as well.
  18. I installed Debian 8 from a USB stick, I don't 100% remember how I did it but I do remember using the network install iso. Maybe this one? https://cdimage.debian.org/cdimage/archive/8.9.0/powerpc/iso-cd/debian-8.9.0-powerpc-netinst.iso What I did was along the lines of: - Find usb stick in OF tree - Overwrite "cd" device using devalias and the OF usb device - Boot yaboot from the usb device There was a LOT of fiddling involved but eventually it worked out. e: I did not try X, I have no idea if it works on these machines still or not.

    Finally got a lime iBook!

    I've done this before and the girls at Starbucks thought it was cute

    Clamshell iBook!

    Yes I did, I used CHANS battery rebuild here in Ontario, I'd definitely recommend them. I had to send another battery because the control circuitry on the first one was fried beyond repair, all in all I'm very pleased. It is better to use ethernet I agree but I wanted something small and compact, unfortunately there are no RNDIS or CDC ethernet drivers for MacOS 9 so it only works in OSX.

    Clamshell iBook!

    If you go the OSX route I personally use a Raspberry Pi Zero W as my WiFi adapter and it works really well. Also the built in airport card will connect to a WPA* (1 not 2) network as long as it's on the latest firmware and on OSX > 10.3.9. *I've gotten it to work on devices where you can set low level settings for the access point. As for batteries you can get them rebuilt, I had my iBook battery rebuilt and it gives a good 4+ hour battery life with the Raspberry Pi plugged into USB. It cost me around $50CAD plus shipping.

    I found a thing lol

    http://imgur.com/a/o9gpg Looks to be a neat keyboard with apparently both an ADB interface and one for the earlier Macs that used that phone jack kind of connector. For $5 it's in pretty good shape but I don't have any ADB macs to test it with at the moment. Still pretty neat though No idea what I'll do with it.

    I found a thing lol

    I might have another one kicking around somewhere, I'll PM you if and when it pops up again.

    I found a thing lol

    I'd totally be willing to send it off to a good home, chances are it'll just sit around here doing nothing. (except looking cool)

    I found a thing lol

    I think I almost have enough to test it in one of those z80 testing circuits except for the lack of a 555 timer. Kinda hesitant to put it on ebay because it's likely just gonna get scrapped, might keep it for the ~~future~~
