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.
Memory cell (computing)
On December 11, 1946 Freddie Williams applied for a patent on his cathode-ray tube (CRT) storing device (Williams tube) with 128 40-bit words. It was operational in 1947 and is considered the first practical implementation of random-access memory. In that year, the first patent applications for magnetic-core memory were filed by Frederick Viehe. An Wang, Ken Olsen and Jay Forrester also contributed to its development. The first modern memory cells were introduced in 1965, when John Schmidt designed the first 64-bit MOS p-channel SRAM. The first bipolar 64-bit SRAM was released by Intel in 1969 with the 3101 Schottky TTL. One year later it released the first DRAM chip, the Intel 1103 that by 1972 beat all worldwide records in semiconductor memory sales.
