Personal acknowledgements to community members, in approximate chronological order.

Jennifer Elaan
For getting me into this mess in the first place
Geoff Stilwell
Not sure if it was him, but whoever it was who gave me the Tulip AT Compact 2 PC, the one that came with the Tulip ATK 030244 that I dug out during the conversation with Jenni (it had been stood in a corner for years as I didn't realise I could connect it to a modern computer, not even my 486 that I had at the time I got the Tulip)
Edgar Matias
For providing the true identity of Xiang Min — the critical first step in the process of unravelling the Mystery of Alps
For success in obtaining the switch manufacturer for AZiO keyboards (Taiwan Tai-Hao), the second step in the Mystery of Alps
Mr Interface
For a complementary switch sample pack
For his keyboard and switch research, and his pointer in the right direction towards unravelling Futaba linear switches
For some free USw LMBW01 switches
For some free Cherry M84A-0100 switches
Various free switches (Marquardt, Alps and Cherry)
For finding the SMK J-M 9031 brochure and solving another mystery (the identity of SMK vintage linear switches)
