==Keyboards==

===PET-derived Mitsumi hybrid: Microgramma===
This appears to be the original and most common keyboard, using the guide shaft plate, sliders and keystem adapters from a [[Commodore PET|PET]] keyboard (like that of the [[Commodore 8032-SK]]), but a revised keyboard matrix. The shift lock switch is likely to be [[Futaba lock]] the same as in the later keyboards. Black tape covers up the unused holes for switch positions not used.<ref name="t1a" /><ref name="t1b" />
The keycap profile is very angular with the same profile for each row and the very wide ''Microgramma Extended'' font.

===VIC-1001: PET-derived Japanese===
The VIC-20 was first introduced in Japan as the '''VIC-1001''', sporting Japanese characters on the front of keycaps and in character ROM.<ref name="denial1001">Denial WIKI—[VIC-1001 http://sleepingelephant.com/denial/wiki/index.php?title=VIC-1001].

The keyboard uses the same switches and keycap style as the earlier [[Commodore PET|PET]], with squarish keycaps and the Latin font being the very wide and angular ''Microgramma Extended''.

===Mitsumi hybrid: Eurostile===
The keycaps are rounder and have a contoured profile. The font is known as ''Eurostile'', which is not as wide as the previous but still squarish.
The switches are similar to the more common [[Mitsumi KSR Type]] with cruciform mount and spring between key and keycap, but the stem is shorter.<ref name="lemon60002">lemon64.com forum—[https://www.lemon64.com/forum/viewtopic.php?t=60002 Vic 20 later Eurostile keyboard restore :)].

===Discrete rubber domes: Narrow font===
Rounder font, similar to Helvetica Narrow. The keycaps are also rounder than the Eurostile variant.
Found in a 1983 Revision D VIC-20, from below this has the same general design as the later keyboard (and that of the [[Commodore 64]]), but instead of using "hybrid" switches, it has sliders over discrete rubber domes that appear to be glued to the PCB. The shift lock switch is still [[Futaba lock]].<ref name="t2" />

===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.
