The GRiD GRiDPad 1910 was one of the first tablet computers ever made. Featuring a wire-tethered, capacitance-based pen, slots for 512kB memory cards, and expansion options including a 2400 baud modem with MNP5 as well as a docking station, this was a relatively complete and entirely standard PC system. It was among the first computers to use 2.5" ATA-interface hard drives.
