I went to school for computer repair. As in- find the bad component on this circuit board, unsolder it and install a new one. PC LANs wouldn't exist in any meaningful way for several more years.
I owe a lot to the sheer luck of timing. I had a good base of knowledge when PC LANs did roll around and I've just been adjusting to new technologies ever since.
What failed to happen was a mass migration to Vista by corporations. They mostly just waited for Win 7.
I'm damned glad that I did, too. My wife was diagnosed with breast cancer a couple of years later (she's fine now). We would have been wiped out if not for insurance.
It's sitting next to an IBM 5150 that I just can't bear to throw out. It still runs. I have Minix on it.
