The 5100 was based on IBM's innovative concept that, using an emulator written in microcode, a small and relatively cheap computer could run programs already written for much larger, and much more expensive, existing computers, without the time and expense of …

Oct 3, 2011 · In 1975, IBM released the first mass-produced portable computer, the 5100. It was an incredible feat for the time: An integrated 5-inch CRT monitor, up to 64 kilobytes of random-access memory (RAM), and the ability to run programs meant for larger, more expensive computers, all in something the size of a briefcase.

The Model 5100 is IBM's first minicomputer, i.e. not a mainframe, and is also considered one of the world's first portable computers. It is preceded only by the Hewlett-Packard HP-9830A from 1973. Although at 55-pounds, the 5100 might best be described as …

The IBM 5100 was marketed as the world’s premiere portable computer. It weighed a little over 50 lbs, and unlike many microcomputers at the time, it came fully assembled with integrated features like a keyboard and CRT display, as well as system software.

Dec 19, 2023 · Part of what made it possible to bring the power of APL processing to a portable system like the IBM 5100 was the IBM PALM processor, which implemented an emulator in microcode to allow...

May 3, 2013 · Six years earlier, Big Blue unleashed a machine called the IBM 5100. It wasn’t just personal. It was portable — at least by the standards of the day. It weighed a mere 50 pounds. In the video...

Nov 22, 2022 · The IBM 5100 combines two legacy “line printer” systems into a more compact “CRT-based” system, with a compact digital data-storage tape unit. The IBM 5100 “Executive ROS” is written in... Some topic highlights: Some remaining goals: I was able to get ahold of Hal Prewitt of Core, who shared some of the early 1980s CORE newsletters.

The IBM 5100 Portable Computer was IBM's 1st attempt to build a personal computer back in 1974. Weighing in at 50 pounds and costing around $10,000, the IBM 5100 had a built-in tape drive, a small CRT and the capability of running programs in either BASIC or APL (A Programming Language, created by IBM).

Introduced in 1975, the 5100 was IBM's first production personal computer (six years before the PC!). The 5100 has an integral CRT display, keyboard, and tape drive. It was available with APL, BASIC, or both, and with 16, 32, 48, or 64 Kbytes of RAM.

The IBM 5100 Portable Computer is a portable computer (one of the first) introduced in September 1975, six years before the IBM Personal Computer. 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.
