Types 386 ISA CPU cards

An ISA CPU card is an industry-standard bus card. Bus cards are printed circuit boards that connect different computer parts and peripherals. The ISA 386 CPU card runs at a clock speed of 12 MHz and has 4 MB of RAM. It can be expanded to 16, 32, or even 64 MB. This card allows peripherals to connect to the system bus and transfer data between devices.

The ISA 386 CPU card supports various operating systems, including DOS, Windows 3.1, OS/2, and Unix. It is compatible with 386-generation computers and has an ISA bus connector. This card has additional slots to connect expansion cards that add more functionality to the computer. It also has serial and parallel port connections for older printers, modems, and other peripherals.

The CPU stands for "cores per unit." Specifications may differ based on core count and frequency. Test results indicate that cards with higher core counts can complete tasks faster. Customers may select a card based on their need for frequency and performance. The various kinds of ISA CPU cards are as follows:

• PC/AT ISA bus cards: These cards are a type of bus expansion card that was commonly used in the early days of PC expansion. Specifically designed for the IBM AT-compatible PC/AT computers, these cards connect to the 8-bit or 16-bit ISA bus, allowing additional functionality or connectivity to be added to the PC.
• Present-day machines come with ISA slots: An ISA (Industry Standard Architecture) slot is a type of expansion slot on a computer motherboard, providing a means to connect additional peripherals or expansion cards to the system bus. ISA is an older standard that was commonly used in PCs, allowing 8-bit or 16-bit cards to be inserted into the slots and giving direct access to the motherboard's bus for communication with other devices.
• The PC/ISA bus card: The PC/ISA bus card stands for Peripheral Component Interconnect/Industry Standard Architecture card. It was created to allow expansion slots on the motherboard. The card connects to the ISA slot and provides serial or parallel ports for usage on older PCs that have limited connectivity options. It has a data transfer rate of 150 KB per second for parallel ports and 115 KB per second for serial ports.
