There's a recent post about it—Dont have the link handy (mobile), but I believe that the sawtooth, specifically, couldnt drive the higher power draw screens of the era, regardless of the graphics card.

Well that's interesting to know. I'm just glad it's not a defect with the machine. I can certainly just use it with the smaller screen.

The dual 450Mhz processor originally came in the Gigabit Ethernet PowerMac G4 (which is what I would guess you really have).

It was the first to support ADC which explains why your 17 incher works. The GigE came stock with an ATI Rage 128 Pro with 16MB of SDRAM. The 23" Cinema Display you have requires 32MB. So seems you just need to upgrade your video card to something like an ATI Radeon 7500 or whatever and should be good to go. :)

I've got enough Macs and monitors that I probably won't worry about trying to make the Sawtooth work with the 23" but I'll keep it in mind.

 

Going back to the PowerBook 165 I mentioned above, I managed to find another very cheap one that turned on with a chime and displayed a blank white screen. I was sort of hoping that the seller just didn't know how to adjust the brightness and contrast and it was actually okay. I did ask them if it had been opened, hoping that it might have a usable hard disk in it. Once it arrived, I found that it didn't do anything but display the white screen, and while there was a hard disk inside, there was no sign of activity from it. It does boot from the boot floppy I made, but there is nothing on the screen.

 

I tried swapping various parts around between my two machines, but was never able to get the screen on the new one to do anything, so I'm guessing it's something wrong with the screen (I tried swapping everything including the board that controls brightness and contrast, but it didn't seem to make a difference. I did apparently solve the issue of the machine restarting when touching the top trackpad button (which I assume was just are result of something shorting somewhere). But no luck with the screen or hard disk, so I'm not much farther along than when I started, although I can pick and choose the components that are the in best shape and make one unit out of them. I do have a new appreciation for how modular these computers were. It's really quite impressive how easy it is to take them apart and swap components.

 

By the way, my old 165 had a modem card in it and the new one didn't. I didn't realize that was optional.

I finally got a PowerMac G4 MDD to "complete" my collection of the major tower designs from the 9600 to the G5 (and cheese grater Mac Pro). It was "untested" so it was a bit of a gamble, but it turned out pretty well. Initially it wouldn't turn on because (I discovered) someone had removed the hard disk and RAM from it. But I borrowed a stick of RAM from my G5, plugged in a Firewire drive and it booted right up. It was listed as a single 1Ghz processor with 2GB of RAM, but turned out to be a dual 1Ghz with 0GB of RAM, so I guess I came out ahead? It also has an Airport Card. I think I have an extra hard drive that I can put in this, but is there any problem just using the 1GB RAM stick I took out of my G5?

I found a "Mac Bottom" on eBay recently for a fairly reasonable price. I don't have an external SCSI hard disk, so I thought I would take a chance on it, even though the seller didn't really seem to know whether or not it worked. When it arrived, the fan inside had broken free of its moorings and was rattling around, and there were no signs of life when I plugged it in. I did test the fuse and it seems fine. I took the drive out of the enclosure and put it in an SE and it booted right up, so worst case scenario I now have another working SCSI hard disk, but I was wondering if anyone else had any ideas about getting the enclosure to work. Could the capacitors cause the problem?

FIrst of all, that’s a nice unit!  Good find.

 

Yeah that’s just a big old power supply in there.  Sure, the caps could be the problem.  You could recap it.  You could also just throw a brand new PSU in there (I think it needs both +5 and +12V?), wire it into the mains plug at the top and solder together a quick harness for that Rodime with some heat shrink and never have to worry about it again until the HD dies.  That would very likely eliminate the need for the fan, too.
