Editing Commodore VIC-20 (section)

===Mitsumi KSR Type: Narrow font===
Rounder font, similar to Helvetica Narrow. The keycaps are rounder still than the Eurostile variant.
This has an identical arrangement to early "bread bin" [[Commodore 64]], with cruciform mount conductive foot Mitsumi hybrid switches, and a non-keyboard switch for shift lock.<ref name="t3" /> The keyboard PCB model is KSR-A66YF.<ref name="t3-2" /><ref name="t3-3" />

Most VIC-20 have orange function keys but some have grey function keys like most [[Commodore 64]]. Similarly some early Commodore 64 have orange function keys.
Whether these variations were intentional or not is unclear.
