| | MOTOROLA 68000 - Definition |
 | | The 68000 was used in many workstations, notably early Sun-2 machines, and personal computers, notably Apple Computer's first Macintoshes and the Amiga. | | | Variants of the 68000 include the 68HC000 (a low-power HCMOS implementation) and the 68008 (an eight-bit data bus version used in the Sinclair QL). | | | The Zilog Z8000 and 68000 are similar in capabilities, but the 68000 is 32 bits internally, making it faster and eliminating forced segmentations. |

| | Meet The 68000 |
| | Although the 68000 has a 16-bit data bus, meaning that 2 bytes of information can be accessed in one machine cycle, internally it can operate on five different types of data: bits, 4-bit binary coded decimal (BCD), 8-bit bytes (B), 16-bit words (W), and 32-bit long words (L). | | | The last register in the 68000 is the 16-bit status register, which is divided into two 8-bit bytes. | | | The 68000 microprocessor may be capable of addressing 16 mega-bytes of memory, but, of the two announced ST models, the 130ST ($399) will contain only 128K of RAM and the top-line 520ST ($599) will have 512K. |

| | DTACK GROUNDED #3 -- September/October 1981 |
| | Once the 68000 has been loaded and the flag byte cleared other BASIC programs can be loaded and run without any modification; the use of the 68000 to perform the math is completely transparent to the user and to the BASIC program. | | | Beginning to work with the 68000 is a smart move at this time for a software house. | | | By examining the 68000 run time for the first three test programs, it is obvious that there is a certain amount of overhead associated with the BASIC interpreter independent of the mathematical process itself. |

| | 68000 Exceptions and Interrupts |
| | They were built into the 68000 architecture to-believe it or not-help make it "bomb proof." A casual user can be locked out of hardware access and be prevented from damaging the system, either accidentally or deliberately. | | | A TRAP is a 68000 instruction which deliberately generates an exception. | | | The answer lies in the fact that the 68000 performs all its interrupts in supervisor mode, and exceptions are nothing but fancy user-called interrupts. |

| | Instruction Set for the 68k |
| | There are 56 basic types in the 68000 instruction set. | | | While the 68000 is a CISC processor, it shares many of the characteristics of its RISC counterparts including fixed length instructions and a small instruction set. | | | There are no special instructions for I/O interfacing as the 68K uses memory mapped I/O. This is an example of the ADD instruction for the 68000. |

| | DTACK GROUNDED #5 -- December 1981 |
| | Command 07 moves bytes to the 68000 from the host, 08 moves bytes from the 68000 to the host, 02 causes the 68000 to go to a location and begin executing code, and 09 transfers small code patches, which is useful for debugging and general code development. | | | THE 68000 IS A REALLY NEAT DEVICE #1: We did not mention this in the earlier writeup on inverting a matrix, but that double precision FP multiply is an outstanding example of the large register space of the 68000. | | | Command 09 requires a 3 byte address, a one byte number which specifies the number of bytes to be sent to the 68000, then the needed code. |

| | We pointed out the irony of the fact that we are offering a very fast 68000 board with a full megabyte of RAM for the Apple II computer, of which there are nearly a million in the field, but that we were not selling large numbers of boards because we have little software to offer. | | | The 68000 is a better match but the PDP-11 is best. | | | A year ago the prevailing view was that the 68000 was such a fast device that operating systems could be written in interpreted p-code. |
