Macintosh SE/30

The Macintosh SE/30 was a computer model of the Apple company. It was introduced in January 1989 and until October 1991 program. Despite the relatively short production time, the SE/30 sold well.

The Macintosh SE/30 used as a Motorola 68030 processor at 16 MHz and a Motorola 68882 as a FPU coprocessor. The case is based on the Macintosh SE with built-in 9- inch screen (512 × 342 pixels, monochrome). However, the motherboard was a new development and with eight 30POL SIMM sockets for up to 128 Mbytes of RAM and said processors for the period offers a remarkable achievement.

Interfaces to the outside world are SCSI ( for external hard drives, CD -ROMs, scanners, printers, removable drives such as Syquest SQ555, imagesetter and later CD burner ); also two serial interfaces ( for modems, LocalTalk, serial Apple printer as the ImageWriter or StyleWriter ), ADB input devices, a high-density floppy disk drive and a headphone jack (8-bit, stereo, 22 kHz PCM, four voices ). In mono sounds can alternatively also be played through the internal speaker.

The board of the SE/30 is practically a Macintosh IIx, equipped only with no NuBus slots, but with a SE/30-PDS ( Processor Direct Slot) Ethernet cards, video cards, CPU cards, GPIB cards and the like. Because of its performance of the SE/30, not least in the graphics industry, but also because of the FPU as number cruncher in the scientific field was very popular. He was often enhanced with a color graphics card and equipped with up to 21-inch monitors for this purpose.

On the SE/30 Mac OS systems running version 6.0.3 to 7.5.5 ( with hacks and 8.1), A / UX 2.0 and 3.0.1, Minix, NetBSD and Linux.

Successor to the SE/30 is the Macintosh Classic II, although it also has a Motorola 68030/16 has, but the bus bandwidth was capped at 16 bit because of memory bus of 32 bits, and the address space for RAM is only 10MB.
