Subject: Macintosh 512K/800 (512ke Variant)
You may want to note this one on the 512Ke page. Like the Macintosh ED, the 512Ke was also sold as the "Macintosh 512K/800" outside of the USA. The main difference between the 512Ke and 512K/800 & ED was that the later two models came with the Mac Plus extended keyboard.
In 1987 along with the rest of the Apple product line, the 512ke and/or variants were also produced in Platinum, this change involved a rear-bucket change of color and a switch to the Macintosh Plus front bezel without the name as depicted in the Macintosh ED on the 512ke page.
