Here there are various designs from over the years. There is a lot more content available for this page, and work is in progress to provide more, so plan to come back and check it out at later dates.
But first, some interesting quotes.
Famous Quotes immortalized in time.
- "Computers in the future may weigh no more than 1.5 tons"
- — Popular Mechanics, forecasting the relentless march of science in 1949.
- "I think there is a world market for maybe five computers."
- — Thomas Watson, chairman of IBM, 1943
- "I have traveled the length and breadth of this country and talked with the best people, and I assure you that data processing is a fad that won't last out the year."
- — The editor in charge of business books for Prentice Hallin 1957.
- "But what ... is it good for?"
- — Engineer at the Advanced Computing Systems Division of IBM, 1968, commenting on the microchip.
- "There is no reason anyone would want a computer in their home."
- — Ken Olson, president, Chairman, and Founder of Digital Equipment Corp., 1977.

Some work and achievements to show the experience that we have to offer
Many of the work / designs show here are from laboratory notebooks or other handwritten designs or notes. They may be concepts, design for breadboard, parts of other designs or systems, reference designs for suppliers, etc. Whether concepts, final designs, or engineering evaluation, they were contributions to product or project development.
Video Related
Analog Video Distribution Amplifier— Multi-channel 200MHz video amplifier designed for high performance Sun Microsystems monitors in the 1990's. Video for conventional displays, usually TV's and related monitors, was based on the low frequency requirements of NTSC video, or 4.2MHz. For high performance Sun monitors of the day, the video approached 100MHz, and there were plans to go higher. Thus the requirement for a high frequency video amplifier.
RGB Encoder — Consulting work to design and lay out an RGB to NTSC encoder.
Traps — General NTSC color subcarrier traps with analysis, presented in a manner that could be used for trapping any unwanted signal component in a signal path.
RF Topics
Delay Line — A Delay Line design analysis, including a hand-plotted delay/frequency plot on semilog paper. (That's the only way we had to do it in the old days.)
EMI Presentation — Parts of a presentation on the concepts of EMI and how they applied to flat panel displays. The concepts are independent of specific product lines, so this applied to electro-magnetic radio in general.
