I could be optimistic and say it’s a Porsche engine!

Looks like a Subaru engine

Erm I might be showing my inexperience here.

Is there no equivalent to man LOAD in the commodore world? Or even just help?

That’s the ticket, IMO. I start off assuming they know, then pause to ask “are you familiar with x concept?”

If they say yes and they really mean no, there’s really not a lot I can do. But it seems to make people feel at ease when talking to me - I don’t get called out for over explaining or infantalizing people this way.
