The Sinclair QL (for Quantum Leap) is a personal computer launched by Sinclair Research in 1984, as an upper-end counterpart to the ZX Spectrum.[3][4][5]
The QL was aimed at the serious home user and professional and executive users markets from small to medium-sized businesses and higher educational establishments, but failed to achieve commercial success.[6]
While the ZX Spectrum has an 8-bit Zilog Z80 as the CPU, the QL uses a Motorola 68008.[7] The 68008 is a member of the Motorola 68000 family with 32-bit internal data registers, but an 8-bit external data bus.[5]
