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!
