Yes, TSRs… the art of loading them in the correct sequence so that you did not make your machine unstable.  Some we really quite useful, for example there was one which I seem to recall was called “Tornado” which allowed you to write linked and indexed notes, a bit like an early Hypercard?

Then there were the ones hooking services to give you access to the RAM between 640kB and 1MB, the ones to page in & out memory > 1MB, oh the horrors… I was really rather pleased with my 386 running Unix!
