“New HP training aid teaches how microcomputers work and how to troubleshoot them when they don’t.” – 1979 Scientific American
A “50-hour” instruction manual would have been supplied with the computer originally. Sadly this had been lost.
In 1979 the 5036A was advertised at $800. That is $2,850 in 2020 (£2,290). Barry Bronson was the principal hardware designer whos team designed and produced the 5036A, along with Michael Slater.
