Hardware Description

Like other desktop compatibles, the Z-151 consists of three components: a display, detachable keyboard, and system unit housing the 4.77 MHz 8088 CPU, disk drives, and electronic innards of the system. The Z-151 was more like an S-100 system than a PC in that it had no motherboard, only an 8-bit PC bus with 8 slots that held the various cards that made up the computer. This made is easy to swap in a new video card or even upgrade the whole computer to a Z-158 with its 8 MHz turbo mode. In terms of style, the Z-151 looks like a piece of military hardware--a touch too boxy.
