I found an ancient Reveal KB-300 keyboard, likely from before 1994, no Windows key and no date on the board and following the FCCID and serial number give me nothing so I can't be sure.
Anyway, it's mechanical and it'd be great getting it working. It's a 5pin Din connector that I've got plugged into a PS/2 converter. When I plug it into my computer, the numlock, caps locks, and scroll lock lights flash on for maybe a quarter of a second and then go dead and no keys work. I haven't tried going into the device manager and looking around but I doubt that'll do much. Anyone have any ideas on how to get it connected to my computer or is this a lost cause?
