Daniel Neeb designed the A1 Electronics Database and implemented it using PHP and HTML.
Alfred Richter created and maintained the first list of A1 modules in 1991 (on a 386 PC).
Arnd Liesenfeld did the inventory of modules in 1998 and provided the original card file.
Ulrich Müller started the database project and contributed some minor bits and pieces.
David Palao did most of the stock-taking in 2001.
We are grateful to Michael Lang and the A2 collaboration who provided us with the PHP source code of their database.
