Thanks Hans for testing and publishing these stats. Very interesting and some surprises indeed!

I would expect different, higher current for the later Topcat units, but I would never guess more than 2:1 difference.

Do you have a Topcat Reserve Power Pack (82037A)? I'd be curious what the current is from there?

At last, a good use for my 82161A ! (though I must admit I was very happy it worked when I found my set of tapes from the 80's a few years ago).
