Amstrad CPC
The ' ("" - which means "small computer" - being a rather literal German translation of the English "microcomputer") is a clone of the Amstrad CPC built by East Germany's ' in October 1989. Although the machine included various substitutes and emulations of an Amstrad CPC's hardware, the machine is largely compatible with Amstrad CPC software. It is equipped with 64 KB memory and a CPC6128's firmware customized to the modified hardware, including an unmodified copy of Locomotive BASIC 1.1. The KC compact is the last 8-bit computer produced in East Germany.

Like the later Apple MacIntosh, the VideoBrain did not allow the user to open the case and insert hardware components. Like the Commodore PET the keyboard was built into the computer. Taking a lesson from videogames, VideoBrain was the first home or personal computer where software programs were stored on ROM chips and loaded into the system in cartridges. This was much easier and more reliable for consumers than loading software from cassette tapes or the notoriously fallible 5.25” diskettes.
In addition to the F8 processor and the proprietary chips, the system contained 1K of RAM and 1K of resident software on ROM. Though the computer’s capabilities were very limited by today’s standards, it is impressive how much the developers were able to accomplish with this seemingly minuscule amount of memory.
