The specific model that Keymacs recreates rarely, if ever, used Hall Effect switches - 365407 used mostly "gundam" aka "space invaders" linear switches that operate somewhat similarly to SKCM used by Keymacs, though some units had ITW mag-valve switches. 36000 keyboard were all Hall-Effect like their predecessor Space Cadet and Knight keyboards. All of them (Knight, Space Cadet, Symbolics) used linear switches.
