A while ago, Matthias Wehrli started to collect information about the countless HP-41 extension modules. He regularly publishes
the updated information as a PDF document on his web site. With permission of Matthias, I converted the
data to a simple online database. Now, you can sort the data or search for specific modules. Hope you enjoy having this information at your fingertips! And if you
happen to know of some extension modules not appearing in the list, let us know.
