Those of us who have been working with computers for a while can remember how lonely it was when something didn’t work. I spent an entire day trying to install a 14,400 modem into my computer in 1994. I had to manually try combinations of DMA interrupts and IRQ channels until I finally fell upon the perfect combination. Nowadays, if we’re having issues with a PC, odds are we have a phone or another PC to use to find internet help.
