Anyway, by end of the 1980s, there would be something like 6 or 7 machines using 8 bit “ISA” for every Apple II bus machine, and 3 or 4 of them for every S-100 based machine. Report comment Reply ...

The VLB is a 16-bit ISA connector with an added 16-bit connector: The VLB bus is a 32-bit bus initially intended to work a bandwidth of 33 MHz (the bandwidth of the first PC 486s at that time). The ...

The ISA bus has some very serious limitations. Even with expansion slots, it is incapable of supporting current-generation I/O requirements, which have evolved from 8/16-bit ISA bus access to ...

The idea is basically simple: 16-bit ISAs take up less code space, even with 32-bit datapaths. The original 68K had an extensible 16-bit ISA and a 32-bit datapath. It's still being used as a code ...

ARC International has developed an instruction set architecture (ISA) that allows mixing of 16 and 32-bit instructions on its 32-bit user-configurable processor. This could cut memory requirements on ...

The Arduino is fast enough to support the ISA bus speed, but the card also needs the PC’s clock line to operate, and it only supports three modes: 80 x 25, 16 colour text, 320 x 200, 256 colour ...

Probably the worst is address space: Addresses on PCI are 32 bits wide, while on ISA they're just 24. IOW, bus mastering devices on PCI can "see" up to 4 GB of host memory, while an ISA bus master ...

That's 32 data bits/lines.<P>The latest PCI spec provides for 64 bit wide data paths, a 64-bit bus.<P>Most busses have a clock rate, like 8 MHz, or 33 MHz, or 66 MHz. The Front-Side buses have 100 ...
