At the risk of going off-topic (Linux and 90's/00's) I'll play too:
1)remembering to set ftp type to binary (that one bit me more than once, at least)
2)learning what a "winmodem" is and avoiding it like the plague!
3)Splitting a partition with FIPS
4)Writing an image to floppy
5)doing anything at all with a floppy, come to think of it
6)Setting jumpers on sound cards and drives
7)learning how to configure XFree86 so that it doesn't blow out your monitor! (never happened to me, but I remember the scary warnings about it: https://www.xfree86.org/4.0.3/chips7.html )
8)configuring PPP internet

What are the 1970’s & 1980’s Computing / IT skills “our grandkids won’t have”?

Whistling into a telephone while the modem is attached, because your keyboard has a stuck key
         - something I absolutely don’t miss.

Having a computer in a grimy wharehouse with 400 days of uptime & wondering how a reboot might go?
