On some or other Facebook group recently LERM Tape Copier was mentioned. This brought back happy memories of creating entirely-legitimate backups of my Spectrum games collection, natch. However, it also prompted both the memory that I always wondered why it was called 'LERM' -- and the realisation that I never found out.
As a decrepit grown-up I'm pretty much assuming that ‘LERM’ is an acronym but I doubt that thought occurred to me as a kid. So, today, I did just a little digging through the SC database to see if I could figure it out. I’m still none the wiser.
The first version is listed as ‘Lerm Tape Copier 4.2’, suggesting there are earlier versions? But let’s park that for now.
While later versions are tagged as being by a one Andrew Machin, version 4.2 is attributed to someone called ‘L Evans’ –- and also evidenced by the same name in the screenshot for 4.2. So, at this point I sense that L Evans is the ‘LE’ in ‘LERM’. So what could be the ‘RM’?
Or does someone here know different/better?
Standby alert 
And yes, my copy of LERM was... a copy. I know this fact wasn't lost on me even at the time.
