Old… but not broken

I’ve just rebuilt one of my home servers. The old one had one of these Arnet Multiport ISA serial cards in it for my packet radio modems. Full-length ISA, full-sized UART chips, shared IRQ serial ports, DIP switches… In other words, all the things that make me glad personal computing moved on past the 1990s.

This card was originally installed in a Pick-based Library automation system in 1993.. Now this is the amazing thing – this card has been operating continuously for 17 years. Realising that made me sit and think. How much technology we use today will be still operable two decades from now? Any of it?
