Macintosh Plus

The Macintosh Plus computer is the third in the Macintosh line. It entered the market in 1986, two years after the original Macintosh. As an improvement to the Macintosh 512K the Plus shipped with 1MByte of RAM, upgradeable to 4MByte, and an external SCSI bus to connect harddrives. The color was in later productions upgraded to a warm gray to replace the old beige color.

The Plus still did not have an internal fan, and this could sometimes cause problems for users. The power supply generated a lot of heat and solder joints would soften and sometimes components would loose contact with the motherboard causing all sorts of problems. When users would bring in their machine for a 4MByte memory upgrade, a fan was installed to alleviate the extra heat that was generated by the extra RAM.
