G3 & G4 General Info

Here a list of G3 and G4 systems I have available. Here a list of G3 and G4 motherboards I have available. I will try to keep these lists current.

When ordering parts, please identify your Mac G3 or G4 system - specifically by motherboard. Apple uses "model M5183" on their cabinets to identify ALL the G3 and G4 "tower" type models by CASE. Sorry about that! You need to check the motherboard part number to know what kind of G4 you have and what parts are compatible. Look at this page for typical motherboard part or model numbers, and features specific to variations of those models. Check the Web for discussions and more information.

Here's some Web site links to inform you about G3 and G4 models and features. This article from Apple's Info site talks about differences among Apple's G4 systems VGA, ADC and DVI video cards and ports. This article from Low End Mac talks about G3 blue and white model differences. This article from AppleLinks.com talks about Yikes! versus Sawtooth.Some info about G3 grey/platinum ROM and motherboard revisions are in this document.

Some customers are interested in upgrading G4 AGP Sawtooth systems to dual processors. This upgrade apparently depends on the version of the motherboard (so called version 2) or revision of the chipset "Uni-N" or "Uni-North" on the motherboard (the uni-n=7 version). To find the version using System Profiler, or the motherboard revision, check this text document". For more information, do a Web search "Uni-N G4 Sawtooth" to find links to descriptions and methods regarding such upgrades. We don't advise on these issues; at best we can try to identify the revisions of items we sell and offer.

Here's a little story as to why I don't often sell G4 "systems". I'm listing these systems below as typical parts sources. Generally, my customers are people who have a G4 which needs parts for their repairs. If I tried to sell "systems", I would have to price them at the total value of their parts. Don't ask "how much for a complete and working system?" because that would cost more, and I cannot warrant a system "for use". Customers who want a complete system, often find a private owner of a no-longer-used system, who will sell it for much less. Or on various Web auction sites. REsult- you may get an incomplete or nonworking system, or one broken in shipping. If so, you can buy repair parts here.

iMac, eMac

The CRT-based iMacs and eMacs have become so inexpensive, that costs and efforts of shipping and packing outweigh the profit I can make from them. Therefore I do not offer these as systems, I only offer a few parts. See my iMac, eMac parts for part prices. We usually keep a few iMacs on hand, and their parts.

For G3 G4 G5 USB keyboards and mice, check my parts page

G3, G4 laptops

Powerbook 3400c "Bongs" but didn't boot up Dec 2021. Clicks and then emits a falling tone three times; repeats. Ran some years ago. So likely a parts source.

Dec 2021: white Apple Macbook 13" 2009 model A1181 - damaged cheap keyboards and trackpads top case assembly for parts. I have several pulled keyboard/trackpad assemblies, for parts like keypads and trackpads. Part numbers are 613-6408 frame 821-0409 trackpad cable. These are used untested no warranties, almost certainly with problems but they have all keycaps and other parts to attempt to repair your keyboard. Sold cheap - $10 plus shipping with cosmetic issues and/or missing keys, $20 plus shipping best cosmetics clean not faded as available. These laptops aren't expensive so these parts aren't expensive. Weight is 10 ounces so can't ship first-class mail: these will cost $10-$16 in Priority Mail postage but a few will cost the same to ship.

Feb 2017: G3 laptop, 333Mhz, likely "Lombard", 320MB memory, bronze keyboard, no DVD decoder. Powers up and boots and runs OS 9. Needs PRAM battery to hold time and date. Primary battery is dead and won't charge. Includes Apple AC "power cord" power supply. Has CD-ROM (read-only) removable drive. We also have ZIP and SuperDrive removable drives.

IBook G4 A1133 date 2005. Parts only, keyboard damaged., dirty, screen not cracked, no battery.

IBook date 2001, M6497. Clean and was functional but had wrong OS installed and did not complete boot to OS. With AC supply, can test; also two batteries not warranted.

Mac laptops before the G3, and their parts, can be found on this Web page. Some unused Mac laptop parts can be found on this linked Web page.

G4 systems

These G4 descriptions are of typical systems. Use these descriptions to help you determine YOUR SYSTEM so you can order the correct parts.

Apple uses "model number" to identify CASES, not systems. Sorry about that! You need to check the motherboard part number to know what kind of G4 you have and what parts are compatible.

Follow this Web link to our G4 parts. We generally sell parts, not systems. Read this note as to why.

Here a list of G3 and G4 systems I may have available for parts and testing. Here a list of G3 and G4 motherboards I may have available. I will try to keep these lists current.

AGP, ADC and 28 volt power supplies

This affects your choice of power supplies and video cards for some G3 G4 G5 models. With the G3 and continuing with the G4 and G5, Apple introduced an AGP graphics card that provides DC power to Apple's monitors (CRT and LCD) thru the Apple "ADC port" connector. Those monitors do not have an AC cord! On the motherboard, the Apple AGP slot (green in photo) and card has an additional tab to carry the 28V DC to the ADC connector, and so to the monitor. and those G4 and G5 models have an AC power supply which includes that 28V. While you can use other monitors with those Macs through the VGA connector, the AGP card and power supply must be replaced with compatible or the same models.

Some new parts are available on a seperate page of unused service parts. They are listed by Apple part number and brief descriptions. Here a list of G3 and G4 systems I have available. Here a list of G3 and G4 motherboards I have available. I will try to keep these lists current.

Parts for grey/platinum G3 systemsCommon parts across several Mac models like power supplies, floppy drives are available on my Mac Parts page. We will list here motherboards, processors, and typical cards for the grey-and-white G3's, such as USB, FireWire and video cards; other PCI bus cards are available on my Mac cards page's PCI section.

Apple SCSI-2 card: Some G3's and G4's were offered with Apple's SCSI-2 controller card and "wide" SCSI-2 (68 pin) drives. See my SCSI PCI card pagefor details on that PCI SCSI card and prices. See my SCSI drive page for SCSI-2 drivs for this card. this Apple article talks about Apple SCSI cards for G3 and G4 systems.

Most of our Mac PCI bus cards for video, SCSI, USB, Firewire, etc., are on our Mac PCI card page.

Memory:Our G3's may be sold with modest amounts of RAM memory. You can buy memory for these systems from us on our Mac memory page.

Drives: Hard drives, ZIP drives and CD-ROM drives (SCSI or ATA/IDE) are available on my drives Web page.

Software: We have none. No OS software, no CD's. Any software on these systems is without warrenty and is not part of the sale price. We just sell hardware.

Some new parts are available on a seperate page of unused service parts. They are listed by Apple part number and brief descriptions. Used parts for many Mac models - power supplies, floppy drives, cables, keyboards and mice, and so on - are listed on our parts page.
