Lot of three vintage do-it-yourself electronic projects from the late 1950s through the late 1970s.

There is a book on how to build your own transistor radio as well as other projects for transistors. It has 34 pages and is copyright 1959.

There is a book on building your own integrated circuit test instruments (a must for the electronic project maker). It has 93 pages and is copyright 1979.

There is also a 1969 book on early computers Digital Computer Lab Workbook with 173 pages.

These books all have some light wear.
