AI was the topic as I presented as one of many presenters in Midwestern State University's Lifelong Learning Center Fall 2025 semester. I've shared the slides, comments and links.

Consider starting with ELIZA and see what AI looked like in the late 1960's. "Tell me more," said Eliza

.By the way, that cabinet under the tester is full of tubes of every different kind. You hope they have the ones you will need.

This photograph shows the detail. On the back is a Roladex of different tube specification. Instruction tell you how to set the rotating knobs below that properly set up a socket specific for the tube type you want to test. Then you push the red button and read the dail — green is good.

If not, then look under the tester and find a new one — seems most were $3 and we would need 3-5 every other month or so.

An advanced builder could use "sweat equity" to inexpensively obtain popular electronic products like HiFi stereo systems, color televisions, CB radios, and automotive test equipment.
