The '''Atom''' was an 8-bit home computer made by [[Acorn]] from 1980 to 1982. It is presently the only device known to use [[MEI Sabrecoil]] switches, and the only other computer besides the [[Acorn BBC Microcomputer]] known to use [[Futaba MR-6C series]] switches.

==Keyboard==
===Issues 1–4===

Issue 4 keyboards are confirmed to use MEI Sabrecoil switches. Issues 1 through 3 likely also used MEI switches, but no pictures of these issues seem to be readily available.

The keycaps are identical to those used with "WEAB" [[MEI T-5 series]] switches.

===Issue 5===
Issue 5 keyboards used cruciform mount Futaba MR-6C series switches.

The issue 5's Futaba keyboard comprises only a plate and switches; the PCB traces are on the motherboard, just as it was with the Sabrecoil variant(s).
