On June 29, 1993, IBM released the first energy star computer, the IBM PS/2 E. The “E” stood for energy. But while it was undeniably more efficient than other desktop PCs, arguably it was a PS/2 in name only. To make the PS/2 E more efficient, IBM used a mashup of technology, including but not limited to borrowing technology from its Thinkpad laptops. To celebrate its green nature, IBM adorned it with a big green stripe across the front. Yes, the stripe was green, not the traditional IBM blue.
