The IBM 5120 Computing System (sometimes referred to as the IBM 5110 Model 3) is a 16-bit microcomputer developed by IBM and released in February 1980.

The IBM 5110 Computing System is the successor of the IBM 5100 Portable Computer. The IBM 5110 was announced in January 1978 (a little over 2 years after the introduction of the IBM 5100). Its main differences were support for more I/O devices (floppy disk drives, IEEE-488 , RS-232 ) and a character set ( EBCDIC ) which was compatible with ...

The IBM 5120 Computing System consists of the IBM 5110 Model 3 Computer, the 5114 external diskette unit, and the 5103 dot-matrix printer. The 5103 printer is a wire matrix printer used by the 5120 computing system. The 5103 printer provides a hard copy of the data at a rate of 80 characters per second or 120 characters per second.

IBM 5120 Computing System 1:> The central component of the 5120 Computing System is the new 5110 Model 3 Computer, a compact, desk-top unit that contains typewriter-style keyboard, a 9-inch CRT display, two diskette drives, a BASIC andlor APL language interpreter implemented in read-only storage,

IBM发布其堂兄 「IBM 5110」于1978年1月，「IBM 5120」发布于1980年2月。 「IBM 5100」于1982年3月停产。 1981年推出的 IBM个人电脑 最初定为「IBM 5150」置于"5100" 系列，但它的架构并非直接源于「IBM 5100」。 IBM 5100基于16 位元 的 中央处理器 模块PALM （P ut A ll L ogic in M icrocode）。 IBM 5100 维护资料手册把 PALM模块 称作 控制器。 PALM 可以直接访问64 KiB 存储空间。 部分IBM 5100配置拥有的ROS (ROM)或 RAM 存储空间超过了64 KiB，所 …

2021年3月29日 · The 5110 and 5120 were essentially the same computer. The 5120, which was introduced in 1980, provided a larger display area. It also eliminated the quarter-inch tape device and added a second 8″ diskette drive. Both of these changes were important. The 5110’s display was so small that some people could not use it.

Het IBM 5120 Computing System (soms ook wel IBM 5110 Model 3 genoemd) is een 16-bits microcomputer die is ontwikkeld door IBM en in februari 1980 op de markt is gebracht.

The IBM 5120 is also known as the IBM 5110-3. In the system I received, some of the manuals say “5120” while the parts summary in the sales paperwork states “5110-3.” I’ve verified that the A1 board cards between the two systems are fully compatible.

The 5120 Computer System featured the new desktop IBM 5110 Model 3 computer and two previously announced products: the IBM 5103 models 11 and 12 bidirectional, matrix printers; and the IBM 5114 diskette unit with up to 2.4 megabytes of direct access storage.
