Working for IBM in the early 90s - they still had "old kit" lying around.
Upright washing machine storage devices, real terminals (not "emulators"), tape reels etc.
I did find a few boxes of punch cards and a small forest of tractor feed. Lordy - they even had a technical library with 2 full time librarians!
Many of my colleagues were "oldies" - who had started on punch cards etc. Plenty of stories about being set up as junior programmers, put onto night shift batch loading - and having a card loader deliberately set up to eject rather than load by the previous shift etc, or having tapes spewing out several dozen feet of expensive brown shiny sellotape per second..
A couple of them were nothing short of geniuses. One little "granny" - with a self-confessed family orchard rather than tree - had helped write SQL. I don't mean she could code in SQL - that she could do like something out of the Matrix - she actually *wrote* parts of the various SQL standards.
I think I've said it on here before. Some of our batch procedures were chewing up more and more overnight mainframe CPU time. It got to the point where Ingrid's jobs were getting squeezed. After a couple of such events she decided to have a look at our team's (of 7 full time coders) work.
One procedure she got down from about 200 lines (not SQL - mainframe procedures) and 1h of mainframe processing to 17 lines and about 4 minutes of CPU. She had basically internalised and visualised every available table, with indexing between them - what temporary tables were created via the plethora of overnight jobs, and what DB2/SQL were best to extract the "goods" with minimal impact.
She did it over a couple of afternoons in between her "real" work.
We just stood there - gawping - as she explained what she'd done. It was about that time that IBM had given her a shiny crystal ornament for her 30 years of service.
