Herb's 68040 Stuff

Mac 68040 machines

Most recent revision of this page dated Mar 5 2024.

On this page we have EXAMPLES of (mostly) 68040-based Quadra, Centris and Performa systems, and cards and accessories for those models. Our PowerMac and "clones" section can be found on another Web page. Check this link for a guide between the various Quadra, LC, Centris and Performa systems. Many of them have the same CPU and "logic" (motherboard, system board) and case but were sold with different amounts of RAM or hard drive capacity. Want to compare processors and speeds? Check our list of systems and processors.

We are primarily selling 68040-based Mac PARTS. We are generally not offering systems. We may not have these sytems for sale; I'm showing them as example systems for convenience. Contact us for prices for specific parts. If you would like parts from these listed systems, like power supplies or logics (CPU cards), or add-on cards, ask for availability and price. A complete list of pointers to our Mac inventory, services and information can be found on my Mac home page.

See this list for available 68040 Mac motherboards. For 68040 systems from which I test parts, see this list.

Here are the Mac I show by system on this page and other pages:

Parts:68040 CPU chips and motherboards are available in our CPU section. Keyboards or mice are available in our keyboard and mouse section of our parts page. Check our memory and hard drive sections for upgrades and prices: Check our power supply section for special prices on those items, or ask for a quote. Also look in the upgrades section of parts for 68040 or PowerMac upgrades. If you would like parts from these listed systems, like power supplies or logics (motherboard/CPU cards), or add-on cards, ask for availability and price. Note: Images below may be models with matching case, refer to the text description for actual features.

When ordering, please follow this link for ordering information, terms and conditions, and info about orders outside the USA.

Quadra / Centris / Performa 68040 and 68030 systems:

See this list for available 68040 Mac motherboards. For possibly available 68040 systems, see this list.

We have a few case and motherboard parts left, ask for specifics. No complete systems of this small "all in one" type case. Also, check our unused service parts list.

Mac Performa 475 68LC040 at 25MHz. 8MB RAM, no hard drive or floppy. LC type PDS slot. Looks much like an LC III case. shipping weight 15 lbs.

Quadra 605 is the same as a Performa 475, is the same as a Performa 476.
Please review my Ordering, Terms and Conditions information before ordering.

Centris 610 is a system with a 68LC040 processor: shipping wt. 18 lbs.
Quadra 610 is the same as the Centris except with a 68040 processor.
For parts, check my parts section or ask.
These systems uses 72-pin DRAM, see the memory section for prices.

See this list for available 68040 Mac motherboards. For available 68040 systems, see this list.

The 620 and 630 systems (630, 31, 635, 636, 637, 638, 640) use the same chassis (case) as the 6200 and 6300 series systems. They all have pull-out logic/CPU boards which are easily removed and replaced. Consider upgrading your 630, etc. system using one of the 6200 or 6300 series logics to a PowerPC! We have removed most of the 620 and 630 systems from our inventory or reduced them to parts. Parts, motherboards, may be available. If you don't see a part, ask!

I have some 630 and 6300 series front panels and back panels. These have fragile "snaps" so some have broken bits. For details, check my PowerMac 6200 6330 parts for similar bezels and case parts. But there are differences so obtain the Apple manufacturing part number that is molded into the plastic part.

638CD system with TV video cards. TV/NTSC video and TV tuner cards. Has CD drive, floppy drive. The 630 series uses either the 68040 or 68LC040 processor.

One TV tuner card for these 630 series and later 6300 and 5300 series systems is 820-549-A. Watch analog TV on your Mac! And I may have the "Apple Video System" card (820-0567-A) for the A/V slot for video input and capture. Similar Apple Video System card are the S-video in/out (820-0737-01) and TV Tuner card (820-0549-A). Check on my Nubus and other cards Web page for prices and details.

Logic card or motherboard for 631, 635, 636, 638, 640: use either of the 630 cards above.

These systems use 72-pin DRAM, see the memory section for prices.
Hard drives and floppy drives and CD drives are available, check the rest of my Web site for prices and models. Or, tell me what system you have and what part you need.

See this list for available 68040 Mac motherboards. For available 68040 systems, see this list.

620 or 630 series power supply is listed on this Web page.

Centris 650:, 68040 at 25MHz, May have "caddy" style CD-ROM drive slot on case, may have no CD drive slot, may have "tray" type CD-ROM drive slot. Hard drive, floppy drive, CD-ROM drive and front slot or "bezel" at extra price. Shipping weight 30 lbs. (Looks like IIvi in picture.)

Quadra 650:, 68040 at 33MHz, at least 12MB RAM (1 SIMMS). Similar features as above. More desirable due to faster processor.

These systems use 72-pin DRAM, see the memory section for prices.

Please review my Ordering, Terms and Conditions information before ordering.

Quadra 700, 800, 900 series

See this list for available 68040 Mac motherboards. For available 68040 systems, see this list.

Quadra 700, 68040 at 25 MHz. 2 NuBus Slots and 1 PDS Slot, Ethernet: AAUI-15. The motherboard part number is 820-0380-A 2 ADB Ports, 2 serial ports. Sound out: stereo 8 bit. It looks like a IIci on its side, very cute. These systems use 30-pin DRAM, and up to 6 VRAM's, see the memory section for prices.
Shipping weight 18 lbs.
Quadra 700, with 4Mb RAM, no floppy or hard drive. PowerMac upgrade card for quadra 700 is in my "parts"...accelerators section.

Quadra 800: 68040 at 33MHZ, shipping wt. 30 lbs.
Uses 72-pin DRAM, 68-pin VRAM: check memory section for prices.

The Quadra 840 A/V is similar to the 800. "The [motherboard] part number is 820-0382-A. The difference between the Quadra 800 and 840av is the presence of onboard S-Video In/Out and the onboard DSP3210 processor. The 840av also has the black DAV connector in line with the topmost NuBus slot." Thanks to customer Shaun Lindon for this information.

Quadra 840AV audio/video system. 68040 at 40MHz. Has S-video in and out, and video in/out. Also AAUI (Apple ethernet) built in, and a few NuBus slots. Shipping weight 30 lbs.
Uses 72-pin DRAM, check memory section for prices.

Quadra 950, 68040 system, very large tower case. They may have a PowerPC 60MHz upgrade car. Given the amount of RAM and the PowerPC card, and the motherboard and power supply, systems like these have held some value. Shipping weight 50 lbs,

Keyboards and mice for the above are available in my parts page under keyboards and mice.

Please review my Ordering, Terms and Conditions information before ordering.

CPU or processor chips, motherboards

We have a number of 68040 and 68LC040 processors at 20Mhz, 25MHz, 33MHz. Ask if we have any 40MHz processors. Prices will depend on market value, ask for current prices.

See this list for available 68040 Mac motherboards. For available 68040 systems, see this list.
