Trenton Conquest Part III

[iamdigitalman]

So, I got another email from my contact in the school district. They said they have more stuff that is going to be chucked, but I can have it. Some good stuff in the preceding email:

Probably not worth your time, then, as most of the stuff I have isn't working...only working stuff is older PowerMacs...one a 6115, another a tower (don't remember the #)..the rest are iMacs in different stages of disassembly and/or repair. One Quicksilver that probably needs a power supply...and then two Blue And White towers without hard drives but working.

Can a B&W G3 power supply be used in a quicksilver? I know the connector is similar, the apple proprietary edition of ATX. If so, I will have a nice QS assembled for use soon.

I'll set it all up so I can go snag it before I head out of town on Thursday.

 

[Unknown_K]

Nope, different supplies.

 

[iamdigitalman]

Is it just a wattage issue, or a slightly different connector? If the latter, I wonder if a B&W supply can be modded. I know an ATX can. I might do that.

Though they said it MIGHT be the supply. I might get lucky and it could be something very simple.

 

[WorkgroupServer]

Quicksilvers have 28volt for the ADC port... not sure if the G3B&W had that....

 

[techfury90]

The B&W lacks ADC, so it does not have the 28VDC line. No tower prior to the GBE does, and additionally, the connectors are different.

 

[iamdigitalman]

ah ok, I forgot about ADC drawing power. I doubt I would use that though, as most of my monitors I have kicking around are VGA. but I'll take a look at it before I invest in a new power supply.

Looks like it won't be until June 8th until I can get it, but still trying to see if I can get this stuff earlier, like before class starts up again.

 

[techfury90]

From what I've heard, its not just ADC that uses that, the PMU uses it too, and its needed to run.

Ghah. Google ATX site:68kmla.org returns:

Mine boots just fine with the +5VSB (standby power) connector from an ATX supply in place of the +28V (and other neccesary pin remappings as detailed on the frankenmac G4 site). You can't use an ADC monitor or any bus-powered Firewire devices, unless you get a powered Firewire hub. If I end up with anything that needs power on FW, I might try a spare +24V Powerbook PS.

Alright, I just got back, slimmer pickings, but I had to cut back, as I am running out of room:

-466mhz Digital Audio (not quicksilver) G4. Has a dead power supply, as it will not do anything when plugged in.

-Power Macintosh 6500/275. Has unknown RAM, HD, or any of that, but it has an ethernet PCI card, modem, video card with VGA adapter. Spray painted orange on one side, florescent green on the other.

-Power Macintosh 6100/66. Has sonnet card, unknown speed or CPU, so it's a mite faster than stock. Included is a keyboard, mouse, AAUI adapter, and video adapter.

-Apple Color Plus 14" Display. Came with 6100. I think I have one of these.

-An odd looking 3rd party keyboard. Says Mac OS on the top with the finder logo, and is ergonomic, with a split between keys.

-A Gravis ADB joystick.

-4 working 3.6 volt PRAM batteries. Had him check them before I got them. One is going into my IIgs.

The G4 came with no RAM, and no HDD. but the video card and SCSI card. I added 768mb of RAM, and an airport card. It also has a Zip 250, and a DVD-ROM drive.

Now to figure out how to get the G4 running again. Would make a nice machine to replace my B&W.

 

[iamdigitalman]

Alright, I had a chance today to test the other machines. The 6100 has a 250mhz G3 upgrade in the slot, but I dug out the DOS compatibility card and cable I had kicking around, and plugged that in instead. It also has a 2.5gb HD, and 72mb of RAM. the CD-ROM does not appear to be working, or else I would load the restore CD.

The 6500 has a 6gb HD, 96mb of RAM, a 500mhz G3 sonnet accelerator, though nothing on the outside said so.

Both machines are running Mac OS 9.1.

Still working on the DA G4. I will attempt to safely dissect the power supply, see what died. If anyone has any thoughts, let me know please.

 

[iamdigitalman]

Alright, I took the power supply out of the DA, opened it up, and took a look around for fuses. Out of the corner of my eye, I saw the silvery glint of the metallic end of a fuse. It was on a board hanging upside down by the power connectors (the DA's PS has 2 power connectors, but the output one is blocked by a sticker like thing. Wonder why they decided not to include this officially...).

Anyways, 2 screws out, and I slowly lifted the board up. It has some wires soldered to it, so I had to rotate it to get to the fuse. I popped it out, and it's a ceramic fuse. it reads 10A, 250v. I looked it up, found a 4 pack for $3 at radio shack here. I will take the fuse to them to have them check it before I pop in a new one, as I can not see any visible signs of it being blown.

If it is not this, then I don't know what it is. But it seems the most likely culprit.

Will keep you all posted.

Sure it might be a fuse, but it could have a short and just pop the fuse again. Who knows though, you might get lucky.

 

[iamdigitalman]

Well, I took the little fuse to rat shack, they tested it and it was good. I took a look at those fuses that are the same voltage and amperage, and they are about twice the size of mine!! I did see some glass ones that are smaller, and are 250v, but top out at about 3 amps, so those would not work.

So, I think it's time I start hunting for a replacement. I have deemed this to be fixable, unlike the eMacs. It's far more expandable, and I can make it go MUCH faster.

Will have to keep hunting for a DA supply. Ebay is my friend.
