Man, Monson put a lot of empty space in his art
...and Google added a lot of crap to it when it got a hold of it.http://groups.google.com/group/sci.electronics.basics/msg/30d98ef099b...
Could Bob be using an oddball font / character set?
..or is Google "improving" things again?

This trick is called a 'baker clamp' for some reason.
The diode prevents the transistor from saturating,
thereby increasing the speed at which it can turn off.

Yup.http://books.google.com/?q=Art-of-Electronics+Baker-clamp+saturation

Opera opened it, but it's true: there's nothing to see there. 8-(

Dead-tree version:  It's listed in the index: clamp, Baker; page 908.- Hide quoted text -

Hi, you're right! My copy of AoE does have a description on Baker
Clamp on Page 584 and also a full chapter on the 8085 micro too. What
a find! Looks like the book was sitting in my book shelf for toooooo
long and I'm going to reread it from the begining again.

Cheers,
