Memory address decoding in the ISA bus for selection of 8-bit or 16-bit transfer mode allowed for some incompatibilities, because the memory address decoding only occurred in 128kb sections. Which made for problems with 8- and 16-bit cards coexisting.

Is 8-bit ISA forwards-compatible with 16-bit ISA?
Most 8-bit ISA cards should work in a 16-bit slot (unless they are hardwired to an incompatible IRQ or have a skirt on them). Some 16-bit ISA cards can operate in an 8-bit slot, but most will not.
What is the Data Bus width for an ISA slot?
ISA slots are available in both 8-bit and 16-bit form.
Which file formats support 24-bit color?
Both PNG and JPG support 24 bit RGB
Isa is a which bit technology?
8/16
What is the ISA expansion slot?
ISA is the precursor to PCI. Standing for "Industry Standard Architecture" It was common from the early 1980s to the mid 1990s. ISA was a typically inelegant solution for the time, and required one to know exactly what one was doing- PnP was rare, even for so called "ISA PnP" peripherals. In the end, the combination of flexibility, ease of use, and greater capability allowed PCI to supersede ISA.
Does Toshiba 2130cs support pcmcia cardbus or only PC card?
It only accepts 16-bit PCMCIA cards.
Does iTunes support Windows 7?
The both versions (32-bit and 64-bit) of Windows 7 are supported.
Does two-bit have brothers in The Outsiders?
Yes. Two-Bit has a younger sister. His mother works as a barmaid to support them both after their father runs out on them.
How do graphics work with old computers?
The newer cards don't work on older computers, but the way the older ones work are similar. The older ones just are not as fast, don't have anywhere as much memory, and don't have as much features. They didn't have as much acceleration and processing, so the drivers (and thus CPU) had to do more of the work. Of the older stuff, the monochrome cards were among the fastest. They were simpler than the color cards and did less, so they were faster. For PCs, there were first the 8-bit ISA cards, then the 16-bit ISA cards, then the VLB cards, then PCI, then AGP, then PCIe. Of course, all along that line of development, there were always motherboards which incorporated the video card as part of it. On one hand, that should be slightly faster that way, but they had limited features, and if they went bad or you wanted to upgrade, you were stuck.
How many pins are in an ISA slot?
The 8-bit slot had 62 pins. The 16-bit slot had an additional 36 pins.
What type of expansion slot do and slower devices use?
The original IBM compatible parts used an 8-bit ISA slot. After that, they moved to a 16-bit ISA slot. There were other things like a VESA slot that didn't last for long. Then there were PCI slots (not express), and AGP was a faster video card slot standard. Then PCI-express replaced both PCI and AGP.
When installing a device why would you prefer to use a pci expansion slot rather that an isa expansion slot?
PCI has several advantages over ISA, that make it a better choice for most devices.1. PCI is several times faster. ISA is an 8/16-bit interface that runs on an 8 MHz bus. PCI is a 32/64 bit interface that runs on a 33 or 66 MHz bis. Thus more data is able to transfer to and from the PCI bus.2. PCI was built with Plug 'n' Play support in mind. No special configuration is needed when you install PCI cards. When installing ISA cards, you will often have to configure jumpers on them to specify an interrupt and DMA channel, and many cards can be incompatible with each other.3. ISA is all but absent from modern computers. One of the requirements for a computer to bear the "Made for Windows 2000" sticker was the removal of the ISA bus. So there have not been any major ISA motherboard vendors in 10 years.
