This page looks at the first MS-DOS coprocessor cards for the Macintosh, the Mac286 and its sibling, the Mac86. I have created this page in response to the lack of information about these cards that is publicly available.
The Mac IIvx was an okay computer, but a big “Huh?” for Mac IIci users. Where the LC and LC II had been compromised by using a 32-bit processor on a 16-bit data bus, the IIvx ran a 32 MHz CPU on a 16 MHz bus. This gave it slower performance than the IIci, which […]
The Mac IIvi is a slower version of the Mac IIvx, running a 16 MHz 68030 CPU on a 16 MHz bus. The IIvi was never sold in the United States. Unlike the IIvx, the IIvi cannot accept a level 2 (L2) cache, although it can accept an accelerator.
The Performa 600 was an okay computer, but a big “Huh?” for Mac IIci users. Where the LC and LC II had been compromised by using a 32-bit processor on a 16-bit data bus, the Performa 600 ran a 32 MHz CPU on a 16 MHz bus. This gave it slower performance than the 25 […]
Six months after moving from 16 MHz to 25 MHz with the IIci, Apple introduced the “wicked fast” 40 MHz IIfx. This was the Mac of choice for graphic designers, offering nearly three times the performance of the IIx – thanks to a lightning fast CPU, a new type of RAM, and special SCSI DMA […]
Building on the success of the Mac IIx, the 1989 IIcx offered the same horsepower in a smaller case. This was made possible by eliminating 3 NuBus slots and using a smaller (90W) power supply.
Building on the success of the Mac II, the 1988 Mac IIx housed a 68030 CPU and 68882 FPU (floating point unit) in the same case. Breakthrough features included the DOS-compatible 1.4 MB SuperDrive (a.k.a. FDHD for floppy disk, high density) and virtual memory. Although advertised as a 32-bit computer, the Mac IIx ROMs were […]
Rolled out in March 1987 along with the compact Mac SE, the Mac II was the first modular Mac – a revolutionary change in the Macintosh line (so revolutionary that it had to be kept secret from Steve Jobs, who loved the simplicity of all-in-one designs). Options include two 800K floppy drives and a hard […]
