[CW] Book Review Published in "CQ Amateur Radio" October 2023 issue.

Mon Nov 27 22:25:52 EST 2023

Back in the day, 1979 or so, I was part of a microcomputer company that
made S100 plugin cards. The tantalum electrolytics  we used had indistinct
markings, so on the production line, we had a "smoke test" fixture that
would apply power to the boards (before the chips went in), and any caps in
backward would go off like a firecracker with a loud pop and bang.
