One of my past colleague is now a system administrator of a few IBM Z Series mainframes1. He is 58 and is the youngest of the team managing this stuff, the other team members are 62 and 72(!). It’s very hard to find people who knows about CICS, IDMS, Ctrl-M, all running on mainframes these days. I started my IT career on an IBM TN3270 connected to a mainframe running MVS. Good memories.

  1. Yep, the world still runs mainframes. ↩︎
