Early Third Party Developers (TPDs)
These developers were founded and released their first products (and in many cases, their only products) during the version 5.x era (or the very late 4.x era). Their modules were likely source code that required the System Operator (Sysop) to modify slightly to set the module number, and compile the add-on into the BBS.
