I worked in a warehouse for a mail marketer. I worked on a system 370 mainframe running dos vse with 1 hard drive (i think it was 50 meg). we had green tubes with a molded in keyboard that weighed a couple hundred pounds. Mind you everyone else gave us their old equipment so they didnt have to pay to get rid of it... tubes broke all the time, you had to climb the shelves in the back, pick a new one and carry it down. Yes i dropped quite a few... I had to run the wires to have a phone at my desk, i had to share a line with 5 other people... there was no documentation, no nothing. we did have shag carpet though. backups, were never done, not even when upgrading the system we have come a long way from my mainframe assembler days...
