Post your favorite keyboard vendors, fan sites, care-and-feeding guides, etc in this thread.
VendorsDas Keyboard - The blank keytop keyboard that seems to be all the rave lately. These use Cherry's gold-plated mechanical switches. Dubbed "the keyboard that clicks".
Unicomp Keyboard Products - The supposed successor to the IBM/Lexmark keyboard kings. According to their website, they purchased Lexmark's keyboard technology from them in 1996.
Clicky Keyboards - THE place to get the real deal. Great source for all things Model M. (it's where I purchased my beloved 84-key space saver)
PFU Systems - Home of the legendary Happy Hacking line of keyboards. I purchased my Happy Hacking Keyboard Professional here...arguably (by ME) the best keyboard in existence.
Fan sites/blogsModelM.org -
TYPE HARD OR GO HOME. Model M fan site. Some links appear to be broken (forum down) and I wasn't able to register my beloved spacesaver here, but I'm going to keep checking this site in the hopes that it sees a revival.
Care and Feeding of an IBM Model M - Title says it all. Good resource for disassembling and cleaning your Model M.
IBM Model M USB upgrade - USB-i-fy your Model M!
