165/155 -- what are those?

Errrr the first 370 line... and I did say 20 + (PLUS)


Ed, you're losing it.
20 years ago was XA.
I started with a 3033, 24 years ago.

If you want I can contact the author and get a real date. But as you indicated old timings don't mean the same thing as they do on new(er) machines.

There is always a cutoff as to the real benefit of and cost of doing I/O . The standalone numbers are almost never close to real life. And trying to do charge back is almost always a loosing battle.
