well, I did a bit of digging, and I found someone with a similar issue here: http://discussions.apple.com/thread.jspa?messageID=4994036 looks like it might just be a power issue …

Got the 2.5.1 ROM? I searched hi and lo for it

According to Mactracker, the sawtooth did come with 8.6 originally, but later came with Mac OS 9.0. It also says it needs Mac OS ROM 2.5.1. I would love a sawtooth running 8.6 It …

I haven't a clue where 1983 came from (other than from my fingers), but 2003 would make a good alternative with a little more credibility. As for the prototype status of the iMac,…

Radeon 9800 Pro Mac Edition, if you don't want to fool around with flashing PC cards is the best.

Is there any way to get 8.6 running on the G4 using these CDs or am I basically screwed without the original? Click to expand... AFAIK, that's a version unique to the sawtooths…

Hm? My Sawtooth came with 9.02 (which crashes left, right and centre, BTW).

If you can flash a 5200, not bad price for some that can handle modern gaming (Not with full settings, but I play Orange Box with it).

if you really want the best video card go for a flashed Radeon 9800 with 256MB VRAM or a flashed GeForce 7 series card. the 9800 gets pretty hot compared to the geforce cards. so …

OK, this is getting really frustrating. I pulled out a SCSI CD drive (actually a burner), and I managed to boot off that (even with no terminator). I used my 9.2.2 CD. With all the…

Thats really quite interesting, equill. Yes, i am still using the original transparent Apple power cable with it. I might have to have a look at the plug and check that its in good…

Don't, without deliberate testing, discount the rôle of the Mac's mains cable in all this. I have had a Snow 500 iMac since new. It has now been always-on since about 1983 but fo…

... But, what all are you wanting to do with it? If you just want it for "2d" stuff, then your 7500 is perfectly acceptable. If you want it for Core Image stuff, then a Radeon 96…

An ATI Radeon 9800 is, I believe, the best video card that was released for that Mac. There was an X800 released, but it requires the 8X AGP slot of the Power Mac G5, so won't wor…

Well you're not going to believe this, but it seems to have come back to life again. I just sat down with it and tried various arrangements of CPU, motherboard and RAM. Eventually …

Hmm, well now this is odd. I tried the direct method once more with the 24x, and it opened just fine, but did not close. I then plugged the molex into the other cable to go to all …

OK, so I double checked the jumper settings. Then I unplugged the IDE cable on the CD-ROM, still nothing. So, I had a hunch, and unplugged the master molex cable, and plugged it di…

Thanks for the advice. The reason for asking was simply that I have a Wallstreet battery with newish cells in which, however, I believe the controller to have failed. It came rece…

I'm sure equill will be able to provide a great deal more about the chemistry, but it is my understanding that over-discharge is dangerous because conductive filaments can form in …

If the cells were ever over-discharged, some controllers will set a nonvolatile bit to prevent recharge. Click to expand... Is that why bunches of these stupid LiIon batteries …

I wonder if you could (i know you guys will hate this) super glue the tabs, then use conductive paint to connect the tabs? so no soldering or spot welding needed?

The controllers must be matched to the batteries, particularly in a lithium-ion pack. More than with any other battery chemistry, lithium-ion requires very special handling to avoi…

The controllers will handle different capacities. Lots of people have re-celled these batteries before. But these people also know what is going with these things very well. They …

Don't recell a LiON or LiPo battery. You're taking your life in your hands, unless you really know what you're doing. The smarts in there stop them asploding in your lap.

Not a small part of the problem seems to be that some software serials were generated only when you supplied the ID number of the particular Newton unit itself on which you wanted …
