The '''Cherry G80-3000''' is a series of [[switch mount|PCB-mounted]] full-size [[Cherry MX]] keyboards manufactured by [[Cherry]]. First introduced in 1988, it is one of the oldest keyboard series still in production. It shares the same case design as the [[Cherry MY]] switch [[Cherry G81-3000|G81-3000]] and the rubber dome [[Cherry G83-3000|G83-3000]], with which it can be easily mistaken. 

== History ==
The first version of the keyboard was first released in 1988, and it has had many revisions.

In many ways it was reminiscent of the [[IBM Enhanced Keyboard]], in layout, with keycaps in a cream and grey colour scheme and with a coiled cable with a DIN plug.
Earlier models had n-key rollover, and until the mid-1990s a PC/XT switch could be found.
The [[Cherry MX]] switches and the keyboard controller occupied a large circuit board that filled both the breadth and depth of the keyboard's case.
The key caps were in [[Double-shot molding|doubleshot]] thick [[ABS]]. The key caps on the bottom row were then of Cherry's "Row A" which was higher and more angled than the row above it.
At this point, the letter code in the [[Cherry article numbers|article number]] was three letters long.

In 1990 to 1992, Cherry produced keyboards with keycaps in thick [[PBT]], with [[Keycap printing#Dye sublimation|dye-sublimated]] legends.
These keycaps from the Cherry G80-3000 are considered by many to be the highest-quality keycaps that Cherry has produced and fetch a high price on the second-hand market.

After a while, dye-sublimation of PBT keys was abandoned for cheaper [[Keycap printing#Laser etching|laser etching]], but the PBT keys were still thick.
At this point, the letter code in the article number grew to five letters.

The biggest change in the keyboard's history came in 1996 with the introduction of Windows keys.
The keyboard remained largely the same on the outside but underwent a lot of internal changes.
The internal PCB was divided into two smaller boards: one for the key switches and one for the controller, where the same type of controller was also used for several other keyboards with the same layout: the [[Cherry G81-3000|G81-3000]], [[Cherry G83-3000|G83-3000]] and the [[Cherry G83-6000|G83-6000]].
The case's walls became thinner, and the LED window cover was removed in favour of three little LED windows. The PCB supports on the inside of the case were also changed, making the old PCB incompatible with the new case (and vice versa).
The four 1.5 [[unit]] modifier keys on the bottom row were changed to seven 1.25 units in the lower Row B profile. While the [[Space bar]] was shortened from 7 to 6.25 units, the position of the key switch remained the same.
Keycaps in PBT became thinner, but the quality of the laser-etching improved.
The PS/2 connector replaced the AT connector.

Since the 2000s, doubleshots on G80-3000 became quite rare and since the end of 2010, Cherry stopped production of any doubleshot key caps. Since the mid-1990 lasered key board legends appeared and became dominant by the 2000s. Black key caps Keyboards are no longer made in cream/grey colour scheme. A "hellgrau" (all light grey) colour was introduced and replaced the cream/grey colour scheme.
Nowadays, keyboards have a USB and PS/2 combo: the connector is USB but the keyboard can talk PS/2 with a passive adapter. The USB controller identifies itself as a "G83 (RS 6000) Keyboard"

The FCC ID of GDD5YOG80-3000 was also used for later production runs of the [[Cherry G80-1000|G80-1000]].

==Rebrandings==
===Das Keyboard===
The second version of the [[Das Keyboard]] (not the one currently offered) was a rebranded black G80-3000 with [[Cherry MX Blue]] switches, blank [[Keycap_construction#POM|POM]] [[keycap]]s and the logo "Das Keyboard" in large bold white letters where the Cherry logo would have been.

===NCR===
[[Double-shot molding|Double-shot]] keys can be slightly darker than on Cherry-branded G80-3000 models, G80-3077, Also, it come with a industrial  grey case.

===Olivetti===
{{Main|Olivetti KBD 2812}}
[[File:Olivetti_G80-3000_004b.jpg|300px|thumb|right|LED cover of Olivetti [[Cherry G80-3011]] HBI.]]

Article number G80-3011 was used for G80 (MX Black) internals inside the normally MY switch Olivetti KBD 2812. Such keyboards still have G81-3000 in the FCC ID, suggesting that these were non-standard assemblies.

===Triumph-Adler===
Modifier keys have white legends on sky blue. Other keys have dark blue legends on light grey.

===Motorola===
This keyboard has article number G80-3055HAU<ref name="3055baidu">[http://tieba.baidu.com/p/3663058977 http://tieba.baidu.com/p/3663058977]</ref>.

All the [[Double-shot molding|Double-shot]] keys are white. Unix layout. And the stepped control key is pad-printed.

===Reuters===

==Possible controller bug==
G80-3000, [[Cherry G80-3600|G80-3600]] (a G80-3000 with 6KRO) and [[Cherry G81-3000|G81-3000]] keyboards exhibit a potential bug with the controller under USB operation. Whenever a keystroke is blocked, a USB report is issued containing 0x0101010101010101. [[Microsoft Windows]] discards this report, while Linux and [[macOS]] will attempt to obey it. The first byte holds the modifier keys, and bit 1 is left control; Linux is confirmed to retrospectively apply the apparent control keystroke to the most recently-pressed key. For example, holding Q, then holding A at the same time, reaches the rollover limit of a G30-3000; when P is then struck with the first two keys held, that keystroke is blocked, causing 0x010101010101010101 to be emitted, which applies left control to the most recently-pressed key (A), causing the system to see Ctrl+A.<ref name="DT-bug" />

The USB HID specification indicates (in Appendix C) that instances of keys being blocked must be reported to the OS, but the wording of the specification is hard to understand and no example is given.<ref name="USB-HID" /> Specifically, the standard specifies:

:The keyboard must report a phantom state indexing Usage(ErrorRollOver) in all array fields whenever the number of keys pressed exceeds the Report Count. The limit is six non-modifier keys when using the keyboard descriptor in Appendix B. Additionally, a keyboard may report the phantom condition when an invalid or unrecognizable combination of keys is pressed. 

Based on the problems displayed, there is a suggestion that only the six non-modifier key position fields should be set to 0x01, giving 0x000001010101010101. Affected Cherry controllers also put 0x01 into the modifier field (first byte) and into the second byte, which is reserved and expected to contain 0x00. Setting those first two bytes to 0x01 prevents the aforementioned operating systems from correctly interpreting the report, but it remains unproven as to where the fault actually lies: it may be that Linux and macOS are misinterpreting a valid report. Cherry have yet to comment.<ref name="DT-bug" />

==Article numbers==
{{Main|Cherry article numbers}}

The G80-3000 is available with different switches, layouts and colours. Modern G80-3000 keyboards have article numbers in the following format:

:G80-3000L'''X'''C'''YY'''-'''Z'''

;L
:[[Keycap printing]], typically L for lasered
;X
:Switch (P = [[Cherry MX Black]], Q = [[Cherry MX Clear]], S = [[Cherry MX Blue]])
;C
:Connector, typically C for combination PS/2 + USB connector
;YY
:Layout (EU = US ANSI with Euro sign, GB = UK ISO, DE = German ISO, etc.)
;Z
:Colour (0 = white, 2 = black)
