Sanaman, tying this to your 128K colour question, the /// & ///Plus mark another change in Apple's colour scheme. The /// Plus should have the new medium-brown keyboard with black characters vs. the original /// which had the chocolate brown keyboard with white characters and accents. My theory here is that the /// was tied to the original Apple ][ and ][+ beige and the /// Plus represented a company-wide change in beige colour & plastics, along with the introduction of the IIe (first with medium-brown keys & white characters, then black), which is also the same beige colour the Lisa uses. Whether this actually happened with the /// and the original keyboard, you are in a good position to tell us. The Mac then was the next departure, followed by the //c which either introduced a new shade of beige on it's accents or continued to use the II, III & Lisa series colour. If a new colour then all the Apple IIs may have switched to it before the change to Platinum. Still some research to be done.
