When I was working in northern Illinois most of my colleagues knew I was a woodworker and because of that I received request for employee or family gifts for various occasions which, in many cases, were going away gifts. I posted one of the going away gifts on Lumberjocks back in August of 2012 (http://lumberjocks.com/projects/68907) which was one of the most complex and atypical. This post is one of the least complex but had to be done in two days.

This project was a going away gift for our technician who built test circuits by breadboarding them for test purposes which in some cases included memory circuits such as the Intel 1702A EPROM.

BREADBOARD
The term breadboard (https://en.m.wikipedia.org/wiki/Breadboard) has changed over the years, originally it was a board to cut bread and also used to build circuits (by driving nails or screws into the board, attach wires as tie point, and solder components) in lieu of anything better. Today there are many commercially available solderless breadboards.

EPROM
This was one of the first EPROMs (Erasable Programmable Read-only Memory) that was available in the early 1970’s. The 1702A was a 2,048-bit (256×8) in a ceramic package with a small quartz window to admit UV light for erasure.

The mounted EPROM Contained all of the names of the members of the department and was signed by those that were available at the time.

My wife had an slightly used breadboard that just needed some sanding to revive it. After sanding I routed a cup into the breadboard, installed a label, the memory circuit, topped off the cup with Plexiglas, and glue/sealed it with silicone. The department manager took the breadboard around for signatures and returned it to me to add a couple coats of lacquer.

Simple and fast all accomplished in two days after work!

I consider this as one very serious project which was very well and clever done.

Thanks everyone!
The project was simple but the description went ”overboard”!
