My earliest memories of seeing computers in action were at the library. Old ADM-3 terminals with light pens to scan in barcodes on the books and on your library card. Plus the muffled sound of a line printer in back doing lists of late check-outs. This would have been in the 1980's. The library I used to go to still had those ADM's well into the '90s, then replaced with gray sided, amber screened WYSE VT-100 lookalikes. But the UI looked the same, so I assume the backend was the same. Anyone know what minis ran library management software back then? I know the university I went to was all Amdhal with 5250 terminals, but the local libraries obviously used something smaller.
