It’s a ballpark number, anything from 100kg+ would have made a 90s equivalent too heavy. The difference compared to consumer computers is expected once you realize it includes multiple interlinked triply redundancy systems and the wiring, mounting structure, power supply system, shielding, etc. for all that.
2 OOMs would translate into a 50 000 kg computer system in 1995 v. a 500 kg computer system in 2015, not 5000 kg.
The computer on a 2015 Falcon 9 weighed 500kg? Really?

A100′s weigh less than 4kg. Three of them would be 12kg. I find it hard to believe that Falcon 9′s use 100kg worth of computer.
