Putatives like P74 and P79: what are they and what are they used for?

Okay I’ve seen many people on this forum mention stuff about putatives, particularly p74 and p79. Just wanted to know what are they and what are they used for? I checked the andotics site and didn’t get much information (as compared to the other products like A314, IS, IO, etc):confused:

The idea is Androtics wants you to figure that out yourself! In other words, you’re the tester. However if you search through the forums, anecdote by anecdote, you can get an inkling of what it’s about. The really good ones become standard products or a component of a standard product. Others go back for tweaking and are resold as a version 2, 3, etc., for customer testing. Perhaps some disappear into the mists of times…

You may have not noticed a similar thread to yours a ways down. I’m sure people won’t want to duplicate their posts…
