Roger Melen
Roger Douglas Melen (1946–2024) was an electrical engineer recognized for his early contributions to the microcomputer industry, and for his technical innovations. Dr. Melen was co-founder of Cromemco, one of the earliest microcomputer companies. At Cromemco he developed color graphics systems that were widely used in television broadcast, and in mission planning systems deployed by the United States Air Force. He also developed the first microcomputer systems widely distributed in China. In addition to his work in microcomputer systems and color graphics, Dr. Melen has made significant technical contributions to the development of CCD image sensors, ultrasonic imaging systems, implantable cochlear devices, image processing technology, and vehicular information systems. He has been recognized as one of the most important inventors and innovators in the history of Silicon Valley. Early contributions As a young man, Roger Melen enjoyed ham radio, operating an amateur radio st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cromemco
Cromemco, Inc. was a Mountain View, California microcomputer company known for its high-end Z80-based S-100 bus computers and peripherals in the early days of the personal computer revolution. The company began as a partnership in 1974 between Harry Garland and Roger Melen, two Stanford Ph.D. students. The company was named for their residence at Stanford University ( Crothers Memorial, a Stanford dormitory reserved for engineering graduate students). Cromemco was incorporated in 1976 and their first products were the Cromemco Cyclops digital camera, and the Cromemco Dazzler color graphics interface - both groundbreaking at the time - before they moved on to making computer systems. In December 1981, ''Inc.'' magazine named Cromemco in the top ten fastest-growing privately held companies in the U.S. In 1987, it was acquired by Dynatech Corporation of Boston. Early history The collaboration that was to become Cromemco began in 1970 when Harry Garland and Roger Melen, gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zilog Z80
The Zilog Z80 is an 8-bit computing, 8-bit microprocessor designed by Zilog that played an important role in the evolution of early personal computing. Launched in 1976, it was designed to be Backward compatibility, software-compatible with the Intel 8080, offering a compelling alternative due to its better Integrated circuit, integration and increased performance. Along with the 8080's seven Processor register, registers and flags register, the Z80 introduced an alternate register set, two 16-bit index registers, and additional instructions, including bit manipulation and block copy/search. Originally intended for use in embedded systems like the 8080, the Z80's combination of compatibility, affordability, and superior performance led to widespread adoption in video game systems and home computers throughout the late 1970s and early 1980s, helping to fuel the personal computing revolution. The Z80 was used in iconic products such as the Osborne 1, TRS-80, Radio Shack TRS-80, Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dynatech
Dynatech Corporation, originally Microtech Research Corporation, was an American technology corporation originally based in Burlington, Massachusetts. The company owned a wide variety of manufacturing subsidiaries across multiple industries, including biomedical equipment, video and broadcast hardware and software, scientific instrumentation, and telecommunications testing, among others. It was founded by 1959 by a pair of Massachusetts Institute of Technology, MIT researchers and soon grew into a multifaceted corporation, helped along by dozens of acquisitions of small niche manufacturers across the United States. At its peak in the early 1990s, the company posted over $500 million in sales, largely generated from its video and telecommunications businesses. Following poor performance in the mid-1990s, the company divested many of its redundant businesses, culminating in its purchase by a private equity company in 1997. In 2000, it began trading as Acterna Corporation. The com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola 68000
The Motorola 68000 (sometimes shortened to Motorola 68k or m68k and usually pronounced "sixty-eight-thousand") is a 16/32-bit complex instruction set computer (CISC) microprocessor, introduced in 1979 by Motorola Semiconductor Products Sector. The design implements a 32-bit instruction set, with 32-bit registers and a 16-bit internal data bus. The address bus is 24 bits and does not use memory segmentation, which made it easier to program for. Internally, it uses a 16-bit data arithmetic logic unit (ALU) and two more 16-bit ALUs used mostly for addresses, and has a 16-bit external data bus. For this reason, Motorola termed it a 16/32-bit processor. As one of the first widely available processors with a 32-bit instruction set, large unsegmented address space, and relatively high speed for the era, the 68k was a popular design through the 1980s. It was widely used in a new generation of personal computers with graphical user interfaces, including the Macintosh 128K, Amiga, ...

Cromemco Dazzler
The Cromemco Dazzler was a video card, graphics card for S-100 bus computers introduced in a ''Popular Electronics'' cover story in 1976.Les Solomon"Solomon's Memory", in ''Digital Deli'', Workman Publications, 1984, It was the first color graphics card available for microcomputers.Harry Garland"Ten years and counting" ''Creative Computing'', Volume 10, Number 11 (November 1984), pg. 104 The Dazzler was the first of a succession of increasingly capable graphics products from Cromemco which, by 1984, were in use at 80% of all television stations in the U.S. for the display of weather, news, and sports graphics. History The Dazzler came about in a roundabout fashion after Les Solomon, Technical Editor for ''Popular Electronics'' magazine, demonstrated the original Altair 8800 to Roger Melen of Stanford University. After seeing it, Melen purchased Altair #2 for his friend Harry Garland to work with. The two built a number of add-ons for the machine, collaborating with Terry Walker on ...
