Abstract
The IBM PS/2® series, introduced in April 1987, was designed as the successor to the IBM PC XT®. It introduced the Micro Channel Architecture (MCA), which replaced the Industry Standard Architecture (ISA), along with innovations such as PS/2 ports, improved 3.5" DD to HD 1. 44MB floppy drives, UART . IBM Personal System/2 series are first released in April, 1 987 in U.S.A. Meanwhile in IBM Japan, they Introduced next personal computer series as IBM Personal System/55. IBM PS/55® is a personal computer series developed and manufactured by IBM® Japan. The IBM PS/ 55 was introduced to Japanese personal computer market a month after PS/2's release. While externally similar to the PS/2, the PS/55 featured several unique hardware and software differences, such as Display Adapter I to V series. As regular users would not open the machine, people often overlooked PS/55 as PS/2 due to its close resemblance to its Western counterpart. Our Computer Restoration group is specialized in repairing non functional computers to function once again. Initially, our goal was to fix IBM PS/2® P70 computers. However, during repair, our team was able to acquire very unique IBM PS/55® 5545- T0B, which is a part of IBM PS/ 55 luggable series. This study aims to document the differences between the IBM PS/2 P70 and the Japanese IBM PS/ 55 5545-T0B, analyzing both hardware and software distinctions. By archiving, our group hopes to contribute to a better understanding of the IBM PS/ 55 series for future generations.
