When keyboards were loud
IBM Beam Spring: The Ultimate Retro Keyboard
Clicky time machine divides fans: bring back the thunder or spare our ears
TLDR: IBM’s beam spring keyboard is a heavy, loud retro icon with a dramatic click and a solenoid thump. Fans rave about the feel, while others worry about noise, and tinkerers debate how to make it work on modern systems—proof that old-school typing still sparks big emotions.
Retro die-hards are losing it over IBM’s beam spring keyboard — the hulking, metal wedge from the 1970s that delivers a massive, satisfying click and even a built-in solenoid thump for extra drama. It’s the ancestor to the famous Model M, but bigger, pricier, and way louder. One nostalgic commenter basically screamed, “Still chasing this feel,” while another marveled at the solenoid — the internal device that fires to make a deliberate ka-thunk so you know you typed something, back when offices were as noisy as factories. Purists want the office thunder back; quiet-clackers are clutching their noise-canceling headphones. Tech tinkerers chimed in too, asking if it plays nice with modern desktops and the X Window System, and pointing to adapters that let these beasts work today. The drama: team nostalgia vs team sanity. Jokes flew about using the keyboard as a gym weight, the hidden wrist-rest compartment being a spy kit, and the solenoid as “doorbell mode.” Meanwhile, old-school fans swooned over IBM’s die-cast metal, quirky terminal keys from the IBM 3270 world, and that flamboyant beam flip that made typing feel like a mechanical event. Verdict? The community is divided—but everyone agrees this thing oozes character.
Key Points
- •Beam spring keyboards predate IBM’s Model F and Model M and offer a highly positive, satisfying key feel.
- •Beam spring operation flips a beam to lift a fly plate off the circuit board, unlike buckling springs that push a hammer onto sensing plates.
- •The IBM 3278 terminal keyboard uses beam spring switches and features heavy, die-cast aluminum construction and a wedge shape.
- •Within the 3270 system, terminals connect via coax to controllers interfacing with mainframes; the keyboard also houses SLT electronics.
- •A solenoid in the keyboard adds loud feedback; enthusiasts adapt these keyboards for modern use via xwhatsit capacitive controllers.
