- Motorola 14500b
processor (MC14500B) A 1-bit ICU from Motorola. Probably the limit in small processors, the 14500B had a 4-bit instruction and controlled a single data read/write line, used for application control. It had no address bus – that was an external unit that was added on. Another CPU could be used to feed control instructions to […]
- Motorola 6800
processor A microprocessor released shortly after the Intel 8080, in about 1975. It had 78 instructions, including the undocumented HCF (Halt and Catch Fire) bus test instruction. The 6800 evolved into the Motorola 6801 and 6803. The 6502 was based on the design of the 6800 but had one less data register and one more […]
- Motorola 68000
processor (MC68000) The first member of Motorola, Inc.’s family of 16- and 32-bit microprocessors. The successor to the Motorola 6809 and followed by the Motorola 68010. The 68000 has 32-bit registers but only a 16-bit ALU and external data bus. It has 24-bit addressing and a linear address space, with none of the evil segment […]
