  1. I did not look at dates, but my 1400c has dual batts while the 1400cs only has one. Am I reading correctly that you are seeing the same thing?
  2. With a 9.0 CD you *should* be able to install the 9.1 update. The exceptions being specific language related IIRC. Try it.
  3. A 1400 should take 9.1 by default. If the installer is not working you might need to check what the localization is, etc. You might do a bit of googling about this if you want 9.2.2: http://eshop.macsales.com/OSXCenter/OS9Helper/Framework.cfm?topic=32 *Edit Oh, looks like it might be a bit more work http://web.archive.org/web/20120204045426/http://www.os9forever.com/Compatibility.html So basically, if you want OS 9, just get 9.1 installed and leave it at that.
  4. Tossing some spare sockets on the free ends of the headers to hold them straight during soldering should help.

    63x series ram slots

    I might be remembering incorrectly, but I was under the impression from some random website that the dual slot boards were the ones that took DOS cards or something. YMMV I do know that my Performa 580 board has two RAM slots and my LC 630 has only one.
  6. One board/chip for ROM, one for hotflashable RAMdisk?
  7. This is a board you could just saw in half for compatibility, is it not? As someone with a plus I am interested in seeing this project develop.
  8. http://en.wikipedia.org/wiki/Heat_spreader "A heat spreader is a heat exchanger that moves heat between a heat source, and a secondary heat exchanger whose surface area and geometry are more favorable than the source." http://www.thermacore.com/products/heat-spreaders.aspx "Heat spreaders let you move heat from within enclosures, where space may be at a premium, to areas with a larger cross-sectional area, surface area and/or volume and a lower heat flux." If you want to get nitpicky, "heat spreaders" you find on RAM are not fitting of that designation unless they are used in this fashion: http://www.creationbs.com/store/index.php/watercooling/cpu-blocks/ek-ram-monarch-x4-nickel-csq.html Anyway, I know both of my WS/PDQ CPUs (and Lombard CPU) had something between the black disk and CPU. I just forget what it was originally. The PDQ is under a pile of stuff atm and I do not remember where I put the old daughtercard. If you look closely at the WS/PDQ & Lombard heatsinks they actually have a heatpipe extending away from the centre where they contact the CPU's spreader. Heatpipes go between centre and left in these pics.
  9. Just so we are on the same page, you are talking about removing the black disc, right? Black disk being the heat spreader held against the CPU die by a square plastic piece around the whole CPU package. Then the big metal plate under the keyboard is the heatsink. On the underside of the black disc I forget what Apple used most commonly, and I would check mine but I am quite certain I squirted some thermal compound under the heatspreaders of my daughtercards after cleaning them out however many years ago. Normally I would want to refer to the disk as an IHS(integrated heat spreader, like what I removed from my i7 4770k! ) but it is not exactly integrated, just more slapped on IMO. Oh, and my mentioning the TL iMac was incorrect, I forgot about it's rectangular heatsink that butts up directly against the die and is held down by a clip to whatever that daughtercard cage thingy is.
  10. A few years ago I pulled my PDQ out and the fan had started running constantly. I unplugged it. Perhaps because I live in Canada or not, I have never heard the fan come on under any load and I had actually tried using it on soft surfaces at some point in the past. The fan in my Lombard also ran constantly. IDK what was up though it had other issues to begin with. Do I remember there actually being thermal compound in the WS/PDQ, Lombard, and TL iMac? Between the CPU die and heatspreader I mean..(the black disk on the CPU) Or was that a little metal shim with an equally thin thermal pad on one side? I forget. these G3s are pretty tame anyway.

    Mac mini PPC/Intel Power Supply

    Internet says 18.5v for 2009 models and earlier, is that right? If both PSUs put out the same voltage but one is lower wattage, then you are talking less current. As long as you do not trip the PSU's overcurrent protection it should work for testing purposes. If anything is going to die it would be the PSU, unless it failed and killed the mini as well. A good PSU should be less likely to kill things attached to it when it goes pop. If anything at all, the mini might *might* be smart enough to throttle itself when used with a lower wattage PSU like IIRC some ancient ThinkPads have been known to do.

    Solar Powered Mac/PC Laptop?

    That is really sad. I used to push four hours with my (very cheap low end model from 2009 keep in mind) HP DV4-1225DX while internetting on a new high capacity battery, and that had a terribly wasteful AMD CPU. IDK what my Thinkpad T510(from 2010 or something mind you) would do with a new battery and I never actually got around to timing the life of it's worn one but I am pretty sure I am still getting around four hours with the same sort of use as DV4. (both using the same Intel 330 240GB SSD and Intel 7260 AC wifi card) Of course DV4's batt started taking a turn for the worse when I replaced it as primary portable so that only lasted a bit over four years. There are new computers that can legitimately run for more than a few hours on a new battery, so please do not judge modern computers based on an old MBA.

    Fixed my Powerbook G4 After Death

    Well, about the thermal compound, I personally have a preference for IC Diamond. Even more so when it is going to be in use for a long time since it resists pump-out. However ICD is likely overkill for a PB. For anything like old notebooks that I care less about or something I am likely to take apart frequently I am still working on a massive tube of AC MX-2 that I got on sale some years ago. It is only my highest-use and fastest computers that I demand better. and TBH "better" might be as low as 1C until that lesser compound pumps out and/or dries up needing replacement. But then I am not even close to a typical usage case scenario either. *shrug* Worth noting that your typical cheap compounds tend to dry up and/or pump out over time, even though initially they might perform within anywhere from 1C-5C of higher quality compounds. That is why I like IC Diamond even though I am not sure where to get it in Canada anymore. I have anecdotal evidence that Antec Formula 7(also a diamond based TIM) is not quite as effective as a 5yr old application of ICD, but still decent and gets used on things like my overclocked i7 4770k for the time being. After running the 4770k for a year I do not have personal results for how it stands up over time though. Aside from a single year being pretty short, I popped the waterblock off to remove the CPU's IHS and run lidless halfway through. If it is not obvious, I am a crazy PC guy so you could probably take what I say sometimes with a grain of salt. For the most part unless you are dealing with insane CPUs or something else, an average thermal compound should be fine for a CPU like a G4. The only way up from diamond is fancy liquid metal stuff(Arctic Silver 5 is not a fancy one btw), and then you are talking real money. Best saved for overclocked high-end CPUs. An example would be http://www.coollaboratory.com/en/products/ I am too cheap for it myself. On the topic of the PB, I am a little saddened that you ran it for two weeks through kernel panics and excessive heat. Good that it is working again. I personally might consider looking at hitting the fan with some lubricant at some point in time since it is ten years old.(WD40 is not a lubricant!) Once the bearings go, they are gone.

    G4 MDD idles at 136 F / 58 C

    I am not sure how hot MDDs normally run but have you made sure the fan you installed was pointing in the correct direction for the MDD case?(and not just the same direction as the previous aftermarket fan was installed) Also, have you checked any other fans to ensure someone did not screw around with them as well?(again, IDK how many fans a MD actually has) At the end of the day though most of Apple's cases are not really known for good airflow. To test your heatsink theory you could close the case and rest the whole thing on it's side, but unless someone altered the mounting hardware it is probably fine. You would be surprised what you can hang sideways!

    Can my SE/30 play doom?

    According to a quick google, DOOM II requires 256 colours and 68LC040 above your setup. http://www.allgame.com/game.php?id=532&tab=sysreqs But you can always try the Shareware MacDoom in the non-DOS section: http://www.doomworld.com/classicdoom/info/shareware.php Apparently Ultimate DOOM requires PPC and colour http://www.allgame.com/game.php?id=13644&tab=sysreqs
