Macintosh Plus

The Macintosh Plus was a computer model of Apple Computer. It was introduced in 1986 and until 1990 in the program.

The Macintosh Plus had a Motorola 68000 with 8 MHz clock frequency and based on the case of the Macintosh 128K and 512K with built-in 9- inch screen (512 × 342 pixels, monochrome), but had more memory (1 MB, upgradeable to as processor 4 MB), a larger ROM (128 KB instead of 64 KB ), and a SCSI interface to which particular external hard disks and removable drives, but also SCSI Ethernet adapter could be connected. The case was initially beige, platinum gray later.

On the inside back of the case, the early Macintosh Plus bore the signatures of the developers. To this end, every employee participated significantly in the development was allowed to make a signature on a paper, which was then etched by Filmmatrize into the existing mold. The result was on the inside of the casing, a relief effect with raised signatures. However, this first master mold did not live long, and there were only the first 70,000 Apple's so cast. Then came a second form in which you operate no longer the expensive cost of subsequent etching.

The Macintosh Plus had no fan; he was rather the chimney effect in the bargain. The ventilation slots on the bottom and on top of the case of the Mac Plus could be covered therefore never, otherwise the Mac overheated quickly and pieces of hardware even by stewing. This was particularly true for the Macintosh Plus, Macintosh 512k (s) and the Macintosh 128k, which were all delivered without a fan.

Although the Macintosh offered a matching connector for a 5.25 -inch drive, you could not connect these drives since you could possibly damage the controller of the Mac. It should therefore only the usual 3.5 -inch drives for 800 KB or Apple SuperDrive (HD drives with 1440 KB ) can be connected.

Successor to the Macintosh Plus was the Macintosh SE, which was equipped with an expansion slot and ADB.
