Will an iMac take a 7410? They can handle a 7400 though.
You'll have to let us know what iMac you have, try Everymac.com, and link us to the exact model you have.

I think, any 7400/7410 are pin compatible, so if you can upgrade to a 7400 you can upgrade to a 7410.

You really need to look at the threads about how @dosdude1 and @LightBulbFun do their cpu rework, they are not trivial swaps, and they have basically rolled their own SMD rework stations.

Back in the day, a few companies offered these CPU reworks, but they had the equipment, including X-Ray machines that they could check the flow of the balls between the CPU and the pad when something went wrong.....

It's really fun and cool to play with these old systems, but it becomes an addiction, and before you know it you have thousands of dollars wrapped up in old Macs, and the only way to get your jones is to buy more hardware:p

Being as how you are 13, I'd say spend your time learning to code, there isn't really much money in hardware, however good or great coders can name their price. I know you didn't say you were doing this for money, but having money helps to buy all the equipment we love to play with.

Yeah... It’s the Special Edition iMac from what I can tell so far. Here’s the link. Picking it up tonight?

It’s the last iMac G3 they had :(

I’m okay at coding, (much) better at hardware :D

Yeah... I’ve been looking at dosdude1 videos and one of them actually is about the iMac G3 CPU upgrade to the G4 7400. Want to do that, but I already ordered my 7410. He said it would only work with the 7400 (I thought? I commented on YT). But yeah, on Christmas, i’m looking forward to buying more parts. I can always sell one of my MacBooks. I have no idea why, but you can get a G4 7410 off eBay for $14, and the G4 7400s are $100! That’s ridiculous! 🤨

Says tray loading... Think it’ll work with a slot loading?

Your iMac is 700 MHz PowerPC 750cx (G3), I think, not compatible with 7400/7410.

You can but the old CPU daughter cards from Sawtooth G4's on the cheap, and re-ball the CPU before you do the swap.

The G3 can do everything the G4 can do sans Altivec, so if you have some software that can benefit from Altivec, sometimes that swap can be worthwhile, tho these systems are long since obsolete, you are not going to be doing modern computing one them.

Really, it's a great/cheap way to learn about hardware, but like I say, it becomes an addiction.:)

Yeah. I’m happy to stick with Tiger. I actually bought the installation retail pack.. can’t believe it costed so much! Hope this iMac has a DVD drive because I do not want to go through more struggles- I have another recurring forum post on what a nightmare it is trying to install Tiger on the iBook G3! It only has a CD drive so I’m using the FireWire port, hooked up to my MacBook.

The grey OEM software install discs are normally a lot cheaper, and with a little work, can be made to do installs.

A lot of times, if you ask, people will throw any old software they have in with Macs when you buy them.

It can be really fun to learn to hack around in Open Firmware to "fool" software installers made for a specific Mac to install on a Mac it doesn't support.

Yeah, I actually watched a video on that when I saw machine-specific install discs for $6! But the seller sent me a private offer; that’s when I caved in. I’ll try to install OS X right now using FireWire. Why is it that each time I click enter in the boot menu that it just refreshes itself? (Cheetah)

Get rid of the “Bad-machines” after making a disk image of it.

How are you trying to do the install?

Most Macs will forward a disc in the optical drive to FW when booted in Target Disc Mode. So insert the Tiger install disc into the MacBook, and boot holding the "T" key.

Boot the iBook holding the OPT key and the Tiger disc should show up to boot from.

Tho, be aware that Tiger PPC and Tiger Intel are not the same install discs, less Tiger Server. So be sure you have the Tiger PPC install disc.

Yup. it’s the PPC disk. I’ve already done that exact method and the same but reverse on the other computer. Tried on multiple macbooks.

You could try creating a second partition on the MacBook's hard drive (you can do this non-destructively within Lion's Disk Utility), copying the Tiger DVD's contents onto that partition (using Disk Utility's Restore pane) and booting the iBook from that partition, again using the MacBook in TDM.

What is the issue you are having?

Tiger disc not showing up in the Boot Picker?

No, it is showing. It’s just when I click the arrow to boot off it, it just refreshes the whole page. I’m pressing the right arrow (not the refresh) but it still refreshes

Yay! I got the iMac for $10. It’s the Graphite Special Edition DV500 MHZ with the 4X DVD drive- Summer 2000!

Everymac just does NOT want to load on my iphone.. oh well..

Is this the special edition model? I thought it was. This seems to be one of the last G3’s. Is this a good model? Anything special about it? Thank u!

Open it and check CPU type; if it's a PPC750L, you can install a 7410 G4.

Ok. Leaving the house now, but when I get back i’ll check. It makes crackling noises and every now and then passes a line through the screen. It’s kind of loud and high frequency. Aren’t there some type of ball bearings on the older drives? Is that why? I’ll try the system profiler, CRT electrocution sounds terrible especially because the iMac keep making noises. Besides that, it works. It shows the flashing finder folder.

Flyback transformer is failing. Common issue on these.

Oh geez, I don’t know how to fix that.. It looks like there’s no OS on it. How do I boot off DVD? The keyboard is weird. It’s the iMac G3 Bondi Blue keyboard. I’ll try the boot menu.

Hold down C and it should boot off a CD if it can read a bootable one in the drive.

Option should bring up boot picker, which will show any bootable volume. You can boot off Firewire, and IIRC this generation iMac can also boot off USB from boot picker. If the latter, be patient as it's slow.

The Bondi KB will work fine, although I don't think the power button will power up the computer.

The keyboard only shuts it off. It’s fine though, I got it from a trade of yesterday. I’ll try the startup boot menu. The DVD drive doesn’t spit it out (Thank God!). How do I restart it, and what are all the buttons on the side. Do I need to shut it off and then turn it on while holding C? On my iBook I usually restart but this iMac G3 gives me the flashing Finder folder because there’s no OS? Or does that mean no HDD?

Tiger was released long after the last iMac G3 was made.

You only need "gray disks"(tray loader restore disks actually orange, IIRC, but I think the slot load iMac disks I have are gray) as a general rule to install the shipping OS on a computer. When installing any supported OS that came after the computer shipped, you can generally use a retail disk.

ok

You can see I issued the devalias command to find the alias to the firewire bus:

Code:
fw                                   /pci@f4000000/firewire

So "fw" is the short name for fw /pci@f4000000/firewire in the device-tree.

Now let's get a look at what devices are on the bus:

Code:
0 > dev fw ls
ff9dc3e8: /node@001451fffe42f4ba
ff9dc5e0:   /sbp-2@4020 
ff9dc828:     /disk@0
ff9dcad0:   /sbp-2@4000
ff9dcd18:     /disk@0
ok

You can see I issued the command dev fw ls ( device firewire list ) what we see here is the children of the firewire bus, and as you can see I have two disks connected. I have one of my iBooks connected in Target Disk Mode, so one disk is the internal hard disk, and the other is the optical drive.

Now let's get a directory of the file system of one of the connected disks to see if it's the OS X install disk:

Code:
 dir fw/node/@4000/@0:,\
sbp2:Open ->login?
speed=2 2 -

     Size/        GMT                      File/Dir

ok

So I issued the command dir fw/node/@4000/@0:,\ ( note I use short names here to save typing the full name would have been fw /node@001451fffe42f4ba/sbp-2@4000/disk@0.

So we can use what comes before the @ or after it, depending on what is easier for use to type, or we could use the whole thing, but that would take way too long.........


As you can see from above the dir of the disk is in fact a Mac OS X Tiger install disk, so let's boot it:

Code:
 boot fw/node/@4000/@0:,\\:tbxi
sbp2:Open ->login?
speed=2 2 load-size=298c4 adler32=24c61a36

parsing <CHRP-BOOT>

evaluating <BOOT-SCRIPT

The command I issued was:

Code:
boot fw/node/@4000/@0:,\\:tbxi

Everything else was the result of that in an Open Firmware telnet session.

If I wanted to boot from the other FW disk I would have issued:

Code:
boot fw/node/@4020/@0:,\\:tbxi

The :,\\:tbxi tells Open Firmware to search the disk recursively for a resource of the type :tbxi.

In this case it found that resource in /System/Library/CoreServices/BootX, as that is the default boot loader for OS X on PowerPC.

The file BootX has a file type in the resource fork of tbxi.

ok

You can see I issued the devalias command to find the alias to the firewire bus:

Code:
fw                                   /pci@f4000000/firewire

So "fw" is the short name for fw /pci@f4000000/firewire in the device-tree.

Now let's get a look at what devices are on the bus:

Code:
0 > dev fw ls
ff9dc3e8: /node@001451fffe42f4ba
ff9dc5e0:   /sbp-2@4020
ff9dc828:     /disk@0
ff9dcad0:   /sbp-2@4000
ff9dcd18:     /disk@0
ok

You can see I issued the command dev fw ls ( device firewire list ) what we see here is the children of the firewire bus, and as you can see I have two disks connected. I have one of my iBooks connected in Target Disk Mode, so one disk is the internal hard disk, and the other is the optical drive.

Now let's get a directory of the file system of one of the connected disks to see if it's the OS X install disk:

Code:
 dir fw/node/@4000/@0:,\
sbp2:Open ->login?
speed=2 2 -

Woah..... I’ll try something like that.

Here’s my mac.


Thought it was indigo; when my dad took a picture of it, looked blue. It has a 30GB HDD, 128 MB of RAM. There’s no OS on it.., but I am pretty sure like @bunnspecial said I should use the grey discs. I’ll try booting off the DVD.

Will the computer work if I leave 128 MB of RAM inside of it and then add a 512 PC133 stick next to it?

What does the “DV SE” mean? Does it stand for something? I can’t figure it out. I just know that they have a DVD drive, right.?
