It has been claimed that in some configurations, a 6800 CPU could actually cause the address lines to literally burn when placed in this mode.

According to statistics from the Ministry of Water Resources, China has invested () since the 1998 Yangtze River floods in repairing and consolidating the country's 9197 degraded reservoirs, of which 2397 are large or medium sized, and 6800 are key small reservoirs.

The extended 8 KB version was then generalized into BASIC-80 ( 8080 / 85, Z80 ), and ported into BASIC-68 ( 6800 ), BASIC-69 ( 6809 ), and MOS Technology 6502-BASIC ( unfortunately spilling over to 9 KB, in an era when 8 KB ROM chips were standard ), as well as the 16-bit BASIC-86 ( 8086 / 88 ).

Like the 6800, it included an undocumented address bus test instruction with the nickname Halt and Catch Fire ( HCF ).

In the end, the 68000 did retain a bus protocol compatibility mode for existing 6800 peripheral devices, and a version with an 8-bit data bus was produced.

Several other buses were designed with minor improvements on the S-100 bus: the 50-pin " Benton Harbor Bus " used in the Heathkit H8 ; the SS-50 Bus used in a variety of 6800 and 6809 computers.

The PIA is designed for glueless connection to the Motorola 6800 style bus, and provides 20 I / O lines, which are organised into 2 8-bit bidirectional ports ( or 16 general-purpose I / O lines ) and 4 control lines ( for handshaking and interrupt generation ).

* 1974: Data Board 4680-the number is a short form of the three microprocessors supported by the bus of this system: Intel 4004, Motorola 6800 and Zilog Z80.

Although the 6501 was not compatible with the 6800, it could nevertheless be plugged into existing motherboard designs because it used the same arrangement of pins.

MOS Technology's first processor, the 6501, could be plugged into existing motherboards that used the Motorola 6800, allowing potential users ( i. e. engineers and hobbyists ) to get a development system up and running very easily using existing hardware.

The 6800 had a minimum clock rate of 100 kHz while the 8080 could be halted.

Initially, the only graphics cards that could power the new 30 " display were the NVIDIA Geforce 6800 DDL series, available in both GT and Ultra forms.

It had originally been named the CDC 6800, but was changed to 7600 when Cray decided it could not be completely compatible.

Designed by Tim Moore the Newbear 77-68 was a kit of parts from which a purchaser could construct a first generation home computer based around a Motorola 6800 microprocessor.

On shortwave ( SW ), the most common frequencies to check for pirates in North America is the 6800 to 7000 kHz ( 42. 86 metres-44. 11 metres ) range, with 6855 ( 43. 76 m ), 6875 ( 43. 64 m ), 6925 ( 43. 32 m ), 6950 ( 43. 16 m ) and 6955 kHz ( 43. 13 m ) being most commonly used, and 6925 kHz being by far the most commonly used frequency.

A close relative, the new X800 XL, was positioned to dethrone NVIDIA's GeForce 6800 GT with higher memory speeds and a full 16 pipelines to boost performance.

Other well known 8-bit microprocessors that emerged during these years were Motorola 6800 ( 1974 ), General Instrument PIC16X ( 1975 ), MOS Technology 6502 ( 1975 ), Zilog Z80 ( 1976 ), and Motorola 6809 ( 1978 ).

It would be a higher-power sibling complementing the existing 8-bit 6800 line rather than a compatible successor.

* Motorola 6800 / 6809, 8-bit

MOS Technology 65xx refers to a family of 8-bit microprocessors from MOS Technology, based on the Motorola 6800 ( introduced ca.

The 6800 was an 8-bit microprocessor designed and first manufactured by Motorola in 1974.

The original Fairlight CMI sampled using a resolution of 16 bits per sample at a rate of 24 kHz, and used two 8-bit Motorola 6800 processors ( later upgraded to the more powerful 16 / 32-bit Motorola 68000 ).

The 6800 family of 8-bit microprocessors ( µPs ) and microcontrollers ( µCs ) is based upon the Motorola 6800 CPU.

In microcomputers, SWTPC's 6800 and 6809 machines used TSC's FLEX disk operating system, Radio Shack's TRS-80 machines used TRS-DOS, their Color Computer used OS-9, and most of the Intel 8080 based machines from IMSAI, MITS ( makers of the legendary Altair 8800 ), Cromemco, North Star, etc., used the CP / M-80 disk operating system.

FORTH, Inc .' s microFORTH was developed for the Intel 8080, Motorola 6800, and Zilog Z80 microprocessors starting in 1976.

After a few centuries it was abandoned for a second settlement, established in 6800 BCE, perhaps by an invading people who absorbed the original inhabitants into their dominant culture.

* Comp Consultants ( later renamed MGlobal ), a Houston-based company originally created CCSM on 6800, then 6809 processors, and eventually a port to the 68000, which later became MacMUMPS, a Mac OS based product.

The 6800 architecture and instruction set were influenced by the then popular Digital Equipment Corporation PDP-11 mini computer.

The 6800 was popular in computer peripherals, test equipment applications and point-of-sale terminals.

*" Motorola 6800 Oral History Panel " Thomas H. Bennett, John Ekiss, William ( Bill ) Lattin, Jeff Lavell.

It was a major advance over both its predecessor, the Motorola 6800, and the related MOS Technology 6502.

The 6809 was source-compatible with the 6800, though the 6800 had 78 instructions to the 6809's 59.

The instruction set and register complement were highly orthogonal, making the 6809 easier to program than the 6800 or 6502.

However, there is a certain amount of design philosophy similarity ( e. g., considerable orthogonality and flexible addressing modes ), some assembly language syntax resemblance, as well as opcode mnemonic similarity, but the 6809 is a derivative of the 6800 whereas the 68000 was a totally new design.

Now produced by Freescale Semiconductor, it descended from the Motorola 6800 microprocessor.

Internally, the HC11 instruction set is upward compatible with the 6800, with the addition of a Y index register.

Several of the designers of the Motorola 6800 left the company shortly after its release, after management told them to stop working on a low-cost version of the design.

At MOS they set about building a new CPU that would outperform the 6800 while being similar to it in purpose.

The resulting 6501 design was somewhat similar to the 6800, but by using several simplifications in the design, the 6501 would be up to four times faster.

While the 68000 family has a 32-bit design, the 68000 used in several early models is generally referred to as 16-bit.

The 68000 has a 16-bit external data bus so must transfer 32 bits of data in two consecutive steps, a technique called multiplexing: all this is transparent to the software, which was 32-bit from the beginning.

Every ATM cell has an 8-or 12-bit Virtual Path Identifier ( VPI ) and 16-bit Virtual Channel Identifier ( VCI ) pair defined in its header.

The 8051 microcontroller has two, a primary accumulator and a secondary accumulator, where the second is used by instructions only when multiplying ( MUL AB ) or dividing ( DIV AB ); the former splits the 16-bit result between the two 8-bit accumulators, whereas the latter stores the quotient on the primary accumulator A and the remainder in the secondary accumulator B.

The IBM System / 360 has a 32-bit architecture with 16 general-purpose registers, but most of the System / 360 implementations actually use hardware that implemented a much simpler underlying microarchitecture ; for example, the System / 360 Model 30 had 8-bit data paths to the arithmetic logic unit ( ALU ) and main memory and implemented the general-purpose registers in a special unit of higher-speed core memory, and the System / 360 Model 40 had 8-bit data paths to the ALU and 16-bit data paths to main memory and also implemented the general-purpose registers in a special unit of higher-speed core memory.

It has two eight-bit accumulators, A and B, two sixteen-bit index registers, X and Y, a condition code register, a 16-bit stack pointer, and a program counter.

The 16-bit PDP-11 instruction set has been very influential, with processors ranging from the Motorola 68000 to the Renesas H8 and Texas Instruments MSP430, inspired by its highly orthogonal, general-register oriented instruction set and rich addressing modes.

The TurboGrafx-16 has an 8-bit CPU and a dual 16-bit GPU ; and is capable of displaying 482 colors simultaneously, out of 512.

The Z80 processor used in the Spectrum has a 16-bit address bus, which means only 64 kB of memory can be directly addressed.

This relationship is the origin of statements like " 16-bit audio has a dynamic range of 96 dB ".

CD audio, for example, has a sampling rate of 44. 1 kHz ( 44, 100 samples per second ), and has 16-bit resolution for each stereo channel.

Each DMA channel has a 16-bit address register and a 16-bit count register associated with it.

VGA was the last graphical standard introduced by IBM that the majority of PC clone manufacturers conformed to, making it today () the lowest common denominator that almost all post-1990 PC graphics hardware can be expected to implement down to the lowest level of hardware registers, obviating the need for any device-specific firmware or driver software ( while all VGA compatible hardware has on-board firmware as well, the only standardized API of that firmware was created for 16-bit real mode and can't easily be used by newer 32-or 64-bit operating systems ).

The processor has seven 8-bit registers accessible to the programmer, named A, B, C, D, E, H, and L, where A is the 8-bit accumulator and the other six can be used as independent byte-registers or as three 16-bit register pairs, BC, DE, and HL, depending on the particular instruction.

As in the 8080, the contents of the memory address pointed to by HL could be accessed as pseudoregister M. It also has a 16-bit stack pointer to memory ( replacing the 8008's internal stack ) This register is always decremented / incremented by 2 during push and pop and a 16-bit program counter.

Like larger processors, it has CALL and RET instructions for multi-level procedure calls and returns ( which can be conditionally executed, like jumps ) and instructions to save and restore any 16-bit register-pair on the machine stack.

Although the 8085 is an 8-bit processor, it also has some 16-bit operations.

It has a 16-bit fixed length instructions for high code density, features a hardware multiply – accumulate ( MAC ) block for DSP algorithms and has a five-stage pipeline.

The PXA271 can be clocked to 13, 104, 208 MHz or 416 MHz and has 32 MB of 16-bit stacked StrataFlash memory and 32 MB of 16-bit SDRAM in the same package.
