The '''Commodore Amiga 2000''' is a computer in the [[Commodore Amiga]] series. The Amiga 2000 is perhaps the Amiga model that has had the most keyboard revisions.

==Keyboards==
The connector is a 5-pin DIN plug. The pins are 1:Clock, 2:Data, 4:Ground, 5:+5V. Pin 3 in not used.<ref name="pinouts" />

===Cherry versions===
This keyboard (in a few variants) was the first generation of keyboards to ship with the Amiga 2000. It was also the first with the "full-sized" [[Amiga#Amiga_keyboard_layout|Amiga layout]] that was used later for all later models, except the (compact) Amiga 600. Among Amiga collectors, the keyboard fetches high prices and is highly sought after, due to its rarity. The keyboard was only in production for the first batch of Amiga 2000 computers (1986–1987){{citation needed}} and was later replaced by a more cost efficient foam and foil variant made by [[Mitsumi]].

The Cherry keyboards are from [[Cherry G80 series]], with Cherry MX switches and [[double-shot]] keycaps,<ref>English Amiga Board &mdash; [http://eab.abime.net/showthread.php?t=31893 Keyboard pictures] &mdash; photo #3 actually shows double-shots keycaps</ref> with a [[Cherry MX Linear Grey]] for the [[space bar]]. The ''Amiga'' keycaps are pad printed. [[Diode]]s are fitted for [[N-key rollover]]. The keycaps are originally featured a slightly lighter almond and light grey colour scheme than the default Cherry scheme.

These keyboards can be recognised by the gaps between the ''Amiga'' keys and the space bar.

The keyboard features a 1-[[unit]] windowed [[Caps lock]] key with a red LED beneath. The US variant has a "big-ass" [[Return key]] that mounts over two switches: the same as the ISO Return and the key next to it.

====Disassembly====
Two case variations have been identified: with either six clips or eight screws on the bottom side. Unfastening them should give access to the keyboard PCB inside.

====Known variants====
*G80-0879HAU (US-layout, PCB-mounted MX blacks) ??
*G80-0904HAD (DE-layout, PCB-mounted MX blacks) ??
*G80-0922 (FI/SE-layout, PCB mounted MX blacks)
*G80-0924 (DK layout, PCB-mounted MX Black)

===Hi-Tek version===
The Hi-Tek keyboard used linear [[Hi-Tek Series 725]] switches,<ref>Reddit &mdash; [https://www.reddit.com/r/MechanicalKeyboards/comments/6evfde/just_got_an_commodore_amiga_2000_keyboard_what/ Just got an Commodore Amiga 2000 Keyboard. What switches are those and how can I connect it to my pc?]</ref> weighted at around 55 cN and with short key travel. The ''Amiga'' keys are black. There is a rivet that can be seen in the gap in-between the ''Del'' and ''Help'' keys. On some NMB keyboards, the left ''Amiga'' key has a Commodore logo on it instead of an italicized ''A''. Some keyboards have switches with yellow sliders, others white.

===Mitsumi version===
The Mitsumi version uses tactile [[Mitsumi KKQ Type]] switches with blue sliders. The keycaps were made from [[ABS]] and yellowed more easily than the earlier Cherry keycaps. Mitsumi keyboards can be told apart from the Hi-Tek keyboards by the decimal point on the numeric keypad not being aligned with the 0 key symbol's baseline, but being higher up.

To accommodate the integrated LED, the caps lock switch is linear.
