High Quality Content by WIKIPEDIA articles! Since the rise of the personal computer in the 1980s, IBM and other vendors have created PC-based IBM-compatible mainframes which are compatible with the larger IBM mainframe computers.

High Quality Content by WIKIPEDIA articles! Since the rise of the personal computer in the 1980s, IBM and other vendors have created PC-based IBM-compatible mainframes which are compatible with the larger IBM mainframe computers. They are also referred to as plug-compatible mainframes, a term used for the original System/360 and 370 compatible clones, although "plug-compatible" is not often strictly accurate since frequently such systems do not support direct attachment of mainframe peripherals. For a period of time PC-based mainframe-compatible systems had a lower price and did not require as much electricity or floor space. However, they sacrificed performance and were not as dependable as mainframe-class hardware. These products have been popular with mainframe developers, in education and training settings, for very small companies with non-critical processing, and in certain disaster relief roles (such as field insurance adjustment systems for hurricane relief).
