Options for ‘040s

2000 – Let’s look at some options for 68040 based computers. If you do not have one, I will discuss which model might be right for you.

Level 2 Cache for the 68040

A Level 2 (L2) cache was a popular way to boost performance on faster 68030-based Macs, including the Mac IIci, Mac IIvx, and Mac IIfx. But none of the 68040-based Macs shipped with an L2 cache, although most were capable of using one. The L2 cache is automatically accessed by the 68040 series processor, whether […]

PowerBook 190

The PowerBook 190 was Apple’s last model based on a Motorola 68040 CPU. The base model has a 640 x 480 4-bit passive matrix grayscale display; the 190cs has an 8-bit color display.

PowerBook 190cs

The PowerBook 190 was Apple’s last model based on a Motorola 68040 CPU. The 190cs has an 8-bit dual-scan passive matrix color display. Apple eliminated the internal modem bay and the ethernet port found in the previous 500 series, forcing buyers to acquire these items separately.

PowerBook 550c

Blackbird was Apple’s code name for a line of PowerBooks based on Motorola’s 68LC040 and 68040 processors. (The LC version draws less power and has no FPU.) The PowerBook 550c was available only in Japan. Differences from the rest of the 500-series include use of regular 68040 (not the stripped down 68LC040), a 750 MB […]

Mac LC 580 (Performa 580)

The LC 580 (a.k.a. Performa 580 and 588) is essentially an LC 575 with a new logic board that supports an IDE hard drive (instead of the more expensive SCSI hard drive used in earlier 500 series Macs) and uses a less expensive monitor.

Quadra 630

The Quadra 630 was the last Mac designed around the 68040 processor. It was designed to replace the Quadra 610. LC and Performa versions of the 630 use the less expensive 68LC040, which lacks an FPU, while the Quadra 630 sports a full 68040. The slide-out motherboard makes upgrades very easy.

PowerBook 520c

Blackbird was Apple’s code name for its first line of PowerBooks based on the 68LC040 processor. (The LC version of the 68040 draws less power and has no FPU.) The 500 series included several firsts: the first portable with a trackpad, the first with a PCMCIA (later PC Card) slot, the first with stereo speakers, the […]

PowerBook Duo 280c

Apple upped the ante by moving from the 68030 to the 68LC040 processor on the Duo 280 and 280c in May 1994. (The 68LC040 is a low power version of the 68040 with the internal FPU disabled.) Other than the CPU, this is essentially a Duo 270c.

PowerBook 540c

Blackbird was Apple’s code name for its first line of PowerBooks based on the 68LC040 processor. (The LC version of the 68040 draws less power and has no FPU.) The 500 series included several firsts: the first portable with a trackpad, the first with a PCMCIA (later PC Card) slot, the first with stereo speakers, […]

Quadra 650

Finding the market confused with five product lines (Mac II, Centris, Quadra, Performa, and PowerBook), Apple renamed the Centris models in October 1993. At the same time, the 68040 CPU in the Quadra 650 was boosted to 33 MHz.

Quadra 610

Finding the market confused with five product lines (Mac II, Centris, Quadra, Performa, and PowerBook), Apple renamed the Centris models in October 1993.

Quadra 605

What was the smallest desktop Mac prior to the Mac mini? Apple’s LC series, which measured just under 3″ tall, although it had as big a footprint as four Minis. And the Quadra 605 (also known as the LC 475 and Performa 475 or 476) was the most powerful model in this diminutive line.

Quadra 840av

Using the same case as the Quadra 800, the 840av incorporates the same AV circuitry as the Centris 660av. Running a 40 MHz CPU, this was Apple’s fastest 68040-based computer ever.

Centris 660av (Quadra 660av)

Initially introduced as the Centris 660av (the two models are identical except for the nameplate), the Quadra 660av shares the same case design as the Centris 610.

Mac LC 630 DOS Compatible and Performa 640

This relatively rare variant of the LC 630 includes a DOS card with an Intel 486DX2/66 CPU, although some shipped with a Cyrix 486/70. The DOS Compatibility card can share Mac motherboard memory or use its own dedicated RAM.

Quadra 800

Apple introduced a new case design with the Quadra 800, one later used by the Quadra 840av and two Power Macs, the 8100 and 8500. Perhaps the most frustrating case to work with, it has three front accessible drive bays. One is for the floppy drive; the others may hold CD-ROM, a DAT drive, a SyQuest mechanism, etc.

Centris 650

Creating a midpoint between the Mac II line and the Quadra series, the short-lived Centris models were introduced in February 1993. The Centris 650 uses the same chassis as the IIvx, IIvi, and Performa 600.

Centris 610

Creating a midpoint between the Mac II line and the Quadra series, the short-lived Centris models were introduced in February 1993. The Centris 610 introduced a new case style, one that would later be used for the Centris 660av and Power Mac 6100.

Quadra 950

Apple replaced the Quadra 900 with the 950, boosting CPU speed from 25 MHz to 33 MHz. Because Apple removed some “wait states” from the video section, the 950’s internal video is about 20% faster than the 900’s – and the faster CPU helps things along even more. The 950 can display 16-bit video on […]

Quadra 900

October 1991 saw the introduction of Macs using Motorola’s high-octane 68040 CPU. The Quadra 900 was a full-fledged tower design, although it had only a single front accessible drive bay. The Quadra 700 and 900 were the first Macs with built-in ethernet, using Apple’s AAUIs connector.

Quadra 700

October 1991 saw the introduction of the firest Macs using Motorola’s high-octane 68040 CPU. The Quadra 700, built in the same chassis as the Mac IIci, was built as a minitower, although with no front accessible hard drive bays. The Quadra 700 and 900 were the first Macs with built-in ethernet, using Apple’s AAUI connector.
