The Q40 and Q60 (sometimes known generically as the Qx0 series) are computer motherboards designed in the late 1990s, based on the Motorola 68040 and 68060 microprocessors respectively and intended to be partially compatible with the Sinclair QL microcomputer.[1] Later these were sold as a fully assembled computer in an AT desktop case.[2][3]
