APH introduced an anodized aluminum model of its pocket slate in 1953. The use of bright anodized colors had become popular in many consumer goods, and the finish also reduced corrosion. The wide variety of colors was reduced to one, gold, in 1963. The interpoint version was introduced in 1990. By the mid 1990s, the company stopped selling the gold in favor of a bright aluminum finish.
