“The ENIAC contained 17,468 vacuum tubes... “
And that’s where the term bug had it’s genesis. A moth got into one of those early beasts with all the tubes and caused some problems. A computer bug.
I’ve been around computers for a couple of years. First one I worked on was a Sperry Univac 1219B missile fire control digital computer, with a whopping 32KB core memory.
I went to computer tech school at Control Data in the mid 80’s.. Was going to be hired by NASA at the Glenn Center, but they had to hire a minority woman. Went to work night shift in a sheet metal shop to pay my bills. Pretty bitter about that. The Control Data school was a complete gov’ment scam.

Had nothing to do with tubes. The incident to which you refer was a moth caught between the contacts of a relay on the Harvard Mark II, which was a relay based computer. It was not a vacuum tube machine at all.
