hobbyist had to obtain all the parts on his own. A company did make the bare printed circuit cards available and the additional parts were a challenge acquire. This limited the number of computers constructed to several hundred or less. To help a 48 page construction guide was made available by the publishers of ’Radio Electronics' for about $5.00. Most likely only a few MARK 8 microcomputers were ever
The publication of the MARK 8 computer in the July issue of 'Radio Electronics' was the very first time a construction article was published. This was noticed by the competing publication 'Popular Electronics' and followed in January 1975 with an article about the "MITS Altair 8800" microcomputer. John was first with the MARK 8 and as a result many computer clubs and newsletters were started to help computer hobbyist build and use the MARK 8.
Here is a the whole article in 'Radio Electronics' from Rich Cini Collector of Classic Computers web site.

It is a pleasure to be a colleague and friend of Dr. John Titus. John and I worked together in the 'Blacksburg Group' in Blacksburg, Virginia (70's & 80's). During this time the group developed popular books about computers & electronics "The Blacksburg Continuing Education Series". The group also developed several popular microcomputer trainers, electronic teaching & development hardware and taught dozens of microcomputer workshops. John did the design and development of all our computers.
Update - Here is John last Column in "Design News" December 2013. John tells about 3 mentors in his career - Gosh I had no idea how John felt about those early days in Blacksburg Virginia. Thank you John for the nice words about our work together - it means a lot to me. Dave 3-31-14
