Reorder Of Past S100Computers Boards
A number of people have expressed interest in obtaining one or more of our past S100 boards.  Many of these S100 boards can be obtained from the RetroBrew Computers WiKi. If you would like a particular board but missed the boat when the board was originally announced and it is not available on the RetroBrew Computers site you may be able to obtain it when I will announce a board reorder run. I hope to do this from time to time (every few months), on the S100Computers Google Groups forum

Note, there are some left over boards from previous orders listed below on this page.

West Coast Computer Festival August 5-6 2017.
The West Coast Computer Festival is coming back to the San Francisco Bay Area. There will be many exhibits on both Saturday and Sunday. You’ll find demos of 1960s minicomputers, 1970s homebrew systems, 1980s eight-bitters, and a few oddities. Some exhibits contain pristine original machines, while others focus on unique modern hacks, and everything in between.  Please mark your calendar for this major event.

Wayne Green, Byte and other Computer Magazine Publisher Passed Away
Wayne GreenI'm sad to say that Wayne Green founder of 73 magazine; Byte magazine; Kilobaud; 80 Micro magazine for the TRS-80 and others passed away on October 30, 2015.   Many of us from the S100 Computers era well remember receiving our weekly copy of Byte and Kilobyte.  These two magazines in particular played a catalytic role in bringing together the home brew computer community.  Our sympathies go out to his family and friends.

Electrical and Electronic Engineers Plaque to Honor Gary Kildall
Pacific Grove, CA.   4/25/2014
The Institute of Electrical and Electronic Engineers installed a plaque on 801 Lighthouse street in Pacific Grove to mark Gary Kildall's development of CP/M in the city 40 years ago this year. The IEEE Milestone program honors important international events in electrical engineering and computing. Achievements, including Thomas Edison's light bulb, Marconi's wireless communications, and Bell Labs' first transistor are recognized with a commemorative plaque in an appropriate location.

A dedication ceremony was held at 2 PM in the City Chambers of Pacific Grove, CA. .  It include a discussion of the legacy of Gary Kildall, featuring Tom Rolander, John Wharton, Brian Halla, David Laws and Gordon Eubanks.  Many legendry figures of the early home computer industry were there.  Also was present was Ted Hoff, who back in 1970 was the person who headed up the development of the Intel 4004 -- the worlds first microprocessor.

   Portrait of Gary.     The discussions took place at the Pacific Grove Town Hall
  Dedication Cermony
The actual unveiling ceremony took place a few blocks away on 801 Lighthouse street  (the original home of Digital Research)
  Plackard 1
     The sidewalk placard -- there for many years to come.
The IEEE provided a nice brochure which contains a summary of Gary's carrier published by Dr. Dobbs Journal back in 1980.

The Trenton Computer Festival

Trenton Computer Festival

This annual event started back in the 1980's and was a must attend gathering for anybody with a S100 bus system in those days.   It has evolved over the decades to a more generalized computer festival.   The next festival is on March 18, 2017 at the usual site -- The Trenton College of New Jersey.

Please see here for further information.
