Which is why the OLD databooks are so important to keep. When the product
is introduced, it is fully supported (app notes, schematics, etc...) but later
edition
data books will have a picture and a price tag... Its become a jelly bean to
the
accountants who are weighing the data books for pennies....

The Internet is boon AND bane... manufacturers are yanking the old data sheets
down at an alarming rate. Once "I" drop the part... fvck those who may have
bought it from me in the past and might want to see the info again... so sad !
