One of my childhood/teen heroes.  I have a bunch of his books.  My CMOS 
cookbook is super dogeared and falling apart and I think this is my second copy 
since I was a kid!  I even have the RTL Cookbook somewhere around here!  I 
loved his Hardware Hacker column in R-E in the 80’s.  He used to imagine this 
thing he called “The Navicube”- a little box that just knows where it is in 3 
dimensions accurately.  This caught my imagination, I played with a lot of 
compass and inertial nav stuff before it was easy,  I guess this is the modern 
GPS.    He wrote a little book about creating a small hacker/craft business 
called “The Incredible Secret Money Machine” that I read much later- lots of 
good advice.  Rest in peace, nice writing style and taught me a lot.
 
Regards,
John M. Wettroth

Don Lancaster, a highly-revered figure in the microcomputer industry for the 
past six decades, peacefully passed away at age 83 on June 7, 2023, in Mesa, 
Arizona. Don’s contributions to the world of microcomputers were exceptional by 
any measure. 
Probably his most notable early achievement was the creation of the “TV 
Typewriter,” a revolutionary device that utilized transistor-transistor logic 
(TTL) to display text on a TV screen. The TV Typewriter first appeared in the 
September 1973 issue of Radio Electronics.  This creation became the basis and 
the title for one of his earliest published books. The prototype of this 
groundbreaking precursor to the modern computer keyboard is showcased at the 
Computer History Museum.  Don also holds a patent for one of the original Apple 
parts he developed as well as having had a hand in the design and manufacture 
of the Apple I keyboard, he was widely recognized as a pioneer in the 
technology field.
His dedication to the computing and electronics industry was evident in his 
extensive body of work. Don authored well over 2,200 technical papers and 44 
books covering a wide-range of topics related to computers and electronics, 
firmly solidifying his reputation as an extremely knowledgeable and prolific 
writer. His insightful contributions could also be found in the pages of 
leading electronics magazines of the 1960s through to the 2000s.   His first 
article appeared in the April 1963 issue of Electronics World.  He also was the 
author behind the wildly popular Hardware Hacker series in Radio-Electronics 
Magazine from January 1988 until June 1995. 
As an instructor at Eastern Arizona College, Don embraced his role as a teacher 
and mentor, imparting his extensive expertise in electronic microprocessing to 
students. Don’s commitment to knowledge dissemination extended beyond 
traditional channels. As the owner and operator of Synergetics and Synergetic 
Publishing, Don and his wife produced educational videos and actively engaged 
with his audience as a blogger – sharing his insights and fostering a sense of 
community. One of his notable accomplishments was the creation of his website, 
Guru’s Lair Resources (www.tinaja.com <http://www.tinaja.com> ), which served 
as a comprehensive repository of computer-related information. Visitors to the 
site could also access his seemingly endless personal research on the 
fascinating hanging canals of the Pinaleño Mountains, explore his extensive 
book collection, and discover details about numerous Gila Valley Day Hikes – a 
topic close to his heart.
Don received an Electrical Engineering degree at Lafayette College in 
Pennsylvania before earning a Master’s degree in Engineering from Arizona State 
University while working at Goodyear Aerospace Corp. Don’s intellectual 
curiosity even led him to nearly complete a second Master’s degree in 
Archaeology at ASU, highlighting his diverse interests.
Don’s contributions to the Apple community extended beyond his technical 
accomplishments. Among his 44 books are the Apple II-centric Assembly Language 
Cookbook volumes, as well as AppleWriter-in-Depth, released in 1984 by 
A.P.P.L.E. These and other contributions over the years to the community will 
be forever cherished.
Left to honor Don’s memory are his beloved wife and daughter, cherished 
grandchildren, and his sister and brother. Their loss is shared by the 
microcomputer industry and the community that esteemed Don for his extensive 
expertise, informative writings, unwavering passion, and dedication to the 
industry.
