If there a chart anywhere showing which carts will work with which versions of PHP?

I have different carts, a 1.3.7, a 1.3.8A, some 1.3.9H version carts, and now 1.5 carts as well.

The 1.3.7 is getting redone to 1.5, which I am fairly certain will not work on PHP 4, as 1.3.9H carts had to be modded in a few places just to work right. (CAN 1.5 run on PHP4--any place showing what to mod on this forum, if so??)

I think the best idea is to upgrade to a new version of PHP.

Most importantly, then, will Zen Cart 1.3.8A still run if I upgrade my system to PHP version 5.2 or 5.3??
