It isn't crazy
I feel sorry for having to remind it on The Register, not a new hipster site that companies in real life run old code as long as it keeps running. MS keeps winning with their operating systems since they can give insane amount of backwards compatibility. Your bank may run 40 year old unmodified assembly code on their 64 bit IBM mainframe and it is expected, not even impressive.
That code hardcopy on paper? Scanner/feeder/high quality OCR.
Biting the hand that feeds IT
