Computer store? Surely you mean Radio Shack!

radio shack? Man I had a computer guy who worked out of his apartment... you'd walk in and the walls would be lined floor to ceiling with desktops from the prehistoric era.

You'd find the guy hunched over a table absolutely loaded with different pcb's, replacing blown caps,,,,

those were the days of actual technicians. These days you only find those guys on youtube.
