Aka, IBM Enhanced Keyboard with Soft Touch

eg, P/N 8184692

Lexmark-made 101-key (ANSI) only Enhanced Keyboard intended for IBM RISC System/6000 workstations. This variant is unique for having their buckling springs factory-greased, which most notably dampens the their ability to resonate (but doesn't completely mute the keyboard). Being an IBM RISC Systems Enhanced Keyboard, it has an internal speaker and requires a specific SDL to PS/2 cable with the normally unused pins (for PC-compatible keyboards) present for driving the speaker.
