My first "real job" mess-up
My first job from college was as 'junior operator/programmer' for a carpet manufacturer. My manager was a fearsome ex Midland Bank executive - she was good as gold once I got to know her - and my technical manager Bob, was a really cool ex USAF guy from Colorado.
I was responsible for the end of day and lunchtime orders consolidation batchwork.
ICL ME29 a bit like this https://www.flickr.com/photos/wades_world/4385072758/ with EDS-80 'exchangeable' disk packs for backup. (72MB formatted!!!!)
Anyway, I'd inherited the JCL and CL command files. The command to backup to disc was CRAFTSEC and the command to restore the files was CRAFTREST - note that you can type them with the left hand...
Of course, on the afternoon shift, I typed CRAFTREST instead of CRAFTSEC and overwrote the afternoons data files.
Fortunately, I was able to restore the lunchtime backup and 'roll forward' the afternoons TPMS transaction log files! (once I'd worked out how the system hung together - phew...)
Needless to say, I changed the names of the commands to something harder to type and rewrote the content to something a little more robust on the checking.
Nice machines the ME29's.
reset - enter - load - enter
to reboot it.
to start a program from the console!
8" floppy discs for loading microcode updates and for me to keep copies of my COBOL programs!
I have a lot of respect for the old-school ICL engineers. The South Wales guys were bonkers, and great company. They really knew how to look after the hardware and the customers.
[sigh] I still miss my ICL VME Series39 machines too! but that's another day...
