Hardware Compatibility
The computer supports most of the interfaces used by the IBM Personal Computer AT* and the Personal System/2* (PS/2*)
products. In many cases, the command and status organization of these interfaces is maintained.
The functional interfaces for the computer are compatible with the following:
Ÿ | The | Intel | 8259 | interrupt controllers | (edge | trigger mode). |
|
Ÿ | The | Intel | 8254 | timers driven from | 1.193 | MHz (channels 0, | 1, and |
| 2). |
|
|
|
|
|
|
ŸThe Intel 8237 DMA
| registers, | and the rotate and | mask functions, are not supported. | ||
| The | mode | register is partially | supported. | |
Ÿ | The | NS16550 | serial | communications controller. | |
Ÿ | The | Intel | Pentium | microprocessor. | |
ŸThe Intel 8086**, 8088**, 80286**, 80386**, and i486DX microprocessors.
Ÿ | The | Intel | 8087**, 80287**, 80387** math coprocessors. | |
Ÿ | The | Intel | 82077AA** diskette | drive controller. |
Ÿ | The | keyboard interface at | addresses hex 0060 and hex 0064. | |
ŸDisplay modes supported by the IBM Monochrome Display and
Printer Adapter, the | IBM Color/Graphics Monitor Adapter, and the |
IBM Enhanced Graphics | Adapter. |
