Bill Moggridge, however, designed the Grid Compass laptop in the year of 1982 around an early flat screen produced by Sharp. This was a yellow-on-black electroluminescent panel that could display 80 characters of text and 320 x 240-pixel graphics.┬áThe Grid Compass 1101 was innovative in its use of storage, too. It didn’t include a floppy drive or a CD drive because the CD hadn’t even been invented. Instead, it was included 384K of non-volatile electronic “bubble memory” developed at Bell Labs. It seemed a promising idea at the time, but rotating hard drives rapidly took over.
