Zenith MinisPort

The Zenith MinisPort was a notebook-sized laptop computer released in 1989 by Zenith Data Systems. It packed a back-lit LCD screen, a battery-backed RAM disk, an internal floppy disk drive, a removable battery pack and a standard-sized laptop keyboard into a case only a little larger than a notebook, and it offered ports for a CRT monitor, a printer, RS-232 serial devices and an external floppy drive. Its most unusual feature was its storage: the MinisPort used 2-inch floppy disks made by Fuji Film, which resembled 3.5-inch disks, and it was the only device to use them, though an external 3.5-inch drive was sold as an extra. The machine was based on an 8 MHz 80C88 processor and had 640 kilobytes of DOS memory plus 384 kilobytes for the RAM disk, sold with either 1 or 2 megabytes of RAM in total.
