The Kenbak-1 has a total of nine registers. All are memory mapped. It has three general-purpose registers: A, B and X. Register A is the implicit destination of some operations.
The Centro de Investigaciones Digitales (CID, "Center for Digital Researches") was formed. The project was directed by Luis Carrasco and mostly designed by Orlando Ramos . The first version was designed using transistors , but after the introduction of integrated circuits , the design was changed.
Direct-coupler transistor logic (DCTL) circuit of the Leprechaun computer. The TRADIC (for TRAnsistor DIgital Computer or TRansistorized Airborne DIgital Computer) was the first transistorized computer in the USA, completed in 1954.
The architecture of the PDP-5 was specified by Alan Kotok and Gordon Bell; the principal logic designer was the young engineer Edson de Castro [8] [9] who went on later to found Data General. Hardware
The PDP-1 (Programmed Data Processor-1) is the first computer in Digital Equipment Corporation's PDP series and was first produced in 1959. It is known for being the most important computer in the creation of hacker culture at the Massachusetts Institute of Technology, Bolt, Beranek and Newman, and elsewhere. [2]
The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer. [3]
ILLIAC IV parallel computer's Control Unit (CU). The ILLIAC IV was the first massively parallel computer. [1] The system was originally designed to have 256 64-bit floating point units (FPUs) and four central processing units (CPUs) able to process 1 billion operations per second. [2]
IBM 701 competed with Remington Rand's UNIVAC 1103 in the scientific computation market. [7] In early 1954, a committee of the Joint Chiefs of Staff requested that the two machines be compared for the purpose of using them for a Joint Numerical Weather Prediction project.
