I would expect that this version is the one to get if you want to develop software:
https://www.ibm.com/docs/en/zdt/12.0.5?topic=personal-edition Personal Edition ZD&T Personal Edition enables a single user to run an IBM® Z distribution on a personal computer. ZD&T Personal Edition can create an environment for mainframe application demonstration, development, testing, and education without Z mainframe hardware. It enables z/OS®, middleware, and other z/OS software to run on Intel and other compatible computers. If you go to this page (https://www.ibm.com/products/z-development-test-environment/pricing), you can start the purchasing process. I expect that the pricing would vary based on your geography, but here in the middle of the US, it says "Starting at $5,380.00* per user per year."
