macintosh portable

 

In september 1989, apple took the first effort to bring a portable macintosh on the market. This first portable macintosh was shipped with Mac OS 6.0.4, weighed nearly 8 kilograms and had a hard drive with up to 40 megabytes. The processor was a motorola 68000 16 MHz clock rate and 0.5 KB of L1 cache. For an additional cost of several thousand dollars, the memory could extend from one to nine megabytes.

 

The active matrix display with 9.8" supported a resolution of 640x400 pixels. Therefore considerably less than an ipad. The macintosh portable was very bulky, heavy, slowly and leaving almost not expand - and cost at least $6,500.

 

Today it is still difficult to find working macintosh portable, on the one hand due to lack of old scsi-harddiscs and on the other due to expiring capacitors. However, the capacitors and also the scsi-harddisc can be replaced by using compact flash-cards. A macintosh portable with compact card starts in about 5 seconds!
