22 | The ARM series is a line of low-power-consumption RISC chip designs | |
f6c8965a | 23 | licensed by ARM Ltd and targeted at embedded applications and |
1da177e4 | 24 | handhelds such as the Compaq IPAQ. ARM-based PCs are no longer |
f6c8965a | 25 | manufactured, but legacy ARM-based PC hardware remains popular in |

63 | The Extended Industry Standard Architecture (EISA) bus was | |
64 | developed as an open alternative to the IBM MicroChannel bus. | |

66 | The EISA bus provided some of the features of the IBM MicroChannel | |
67 | bus while maintaining backward compatibility with cards made for | |
68 | the older ISA bus. The EISA bus saw limited use between 1988 and | |
69 | 1995 when it was made obsolete by the PCI bus. | |
