I just noticed that my post count has reached the dizzy lows of 2000 and it brought to mind all my old submarine sonars! And I haven't been drinking. Much. So, obviously, starting with that electro mechanical behemoth 2001 and now up to 2016. Got a few more old bits of kit of go before I can lie down! 2020 can pass me by as I never had it! How sad is that?
