![]() Memory could be 16 KB, 32 KB, 48 KB or 64 KB of main There were twelve models available: with BASIC, APL, or both. The actual APL and BASIC interpreters were stored in a separate Language ROS address space which the PALM treats as a peripheral device. Some configurations of the IBM 5100 had Executable ROS ( ROM) and RAM memory totalling more than 64 KB, so a simple bank switching scheme was used. The PALM could directly address 64 KB of memory. The IBM 5100 Maintenance Information Manual also referred to the PALM module as the controller. The IBM 5100 is based on a 16- bit processor module called PALM ( Program All Logic in Microcode). In 1973, APL was generally available only on mainframe computers, and most desktop sized microcomputers such as the Wang 2200 or HP 9800 offered only BASIC.īecause SCAMP was the first to emulate APL\1130 performance on a portable, single user computer, PC Magazine in 1983 designated SCAMP a "revolutionary concept" and "the world's first personal computer". SCAMP emulated an IBM 1130 minicomputer in order to run APL\1130. The IBM Los Gatos engineering prototype and a design model by IBM Industrial designer Tom Hardy, were utilized internally by Lowe in his early efforts to demonstrate the viability of creating a single-user computer. SCAMP has been dubbed in PC Magazine as "the world's first personal computer". Paul Friedl and a team at the IBM Los Gatos Scientific Center. In 1973, Bill Lowe was instrumental in fostering an engineering prototype called SCAMP (Special Computer APL Machine Portable) created by Dr. The IBM 5100 was withdrawn in March 1982, by which time IBM had announced its larger cousins, the IBM 5110 (January 1978) and the IBM 5120 (February 1980). ![]() Previously, a truck-based IBM 1401 configured in 1960 for military use was designated a portable computer, and nicknamed a DataMobile. ![]() The 5100 was IBM's second transportable computer. When the IBM PC was introduced in 1981, it was originally designated as the IBM 5150, putting it in the "5100" series, though its architecture was unrelated to the IBM 5100's. Whether considered evolutionary from SCAMP or revolutionary, it still needed to be plugged into an electric socket. It was the evolution of a prototype called the SCAMP (Special Computer APL Machine Portable) that was developed at the IBM Palo Alto Scientific Center in 1973. The IBM 5100 Portable Computer is one of the first portable computers, introduced in September 1975, six years before the IBM Personal Computer, and eight before the first successful IBM compatible portable computer, the Compaq Portable.
