Dye-sublimation PBT keycap swap compatibility

Cherry ErgoPlus never came with the Dye-sublimation PBT keycaps like most old Cherry keyboard. Swapping keys from a newer or otherwise semi-mechanical (G81) keycaps is possible however there are a few catches. This is in comparison with G81-3000 for instance:

• The spacebar is incompatible. There are no suitable PBT replacements.
• Most of the keys on the bottom row are incompatible as they used the lower profile (Profile B) keys. There are certain models that were equipped with either higher or lower profile keys but there are none suitable as noted for ErgoPlus. HAAxx series uses higher profile (Profile A) keys however the HAMxx series uses the lower profile making certain keys stand out more after the keys has been replaced. The variance in the height profiles are not limited to the keys on the bottom row but to also the modifier keys to the far right of the keyboard such as: Insert, End, Delete, etc.

xxxUS conversion

ErgoPlus came in various (mostly European but also American) layouts. However not many owners of the ISO variant are comfortable using the ISO variant and instead sought ways to convert their ErgoPlus to ANSI layout. Out of all the intentions of ISO to ANSI conversion, very few have actually attempted to convert their ErgoPlus fully due to the fact that specific knowledge to making keyboards (notably PCB) is somewhat required.

In any case, there is a thread on geekhack forums where one has asked had there been any interests to convert ISO layout to ANSI layout.

Original transcript as written on Cherry website before it became no longer available

Here is a copy from wayback machine (web.archive.org) which mirrored the webpage discussing (lightly) about G80-5000 along with ergonomics. German only

Einige beispielhafte Erläuterungen der Anforderungen an Computertastaturen:

1. Erlaubt die Tastatur eine körpergerechte Haltung?

Die Tastenblöcke müssen für beide Hände so angeordnet sein, dass eine Ulnardeviation (d.h. eine Entzündung im Bereich der Fingergrundgelenke) aufgrund einer unphysiologischen Handhaltung vermieden wird. Die Höhe, Neigung und Wölbung der Tastatur erlaubt, dass die Hände ohne zusätzliche Anspannung gehalten werden können.

Studien haben zwar gezeigt, dass ein so genanntes „gebrochenes Tastaturenlayout“ die ergonomisch beste Handauflage ermöglicht, doch Modellversuche in den letzten Jahren erzielten im Markt nur eine sehr geringe Akzeptanz dieser ungewohnten Tastaturform. Bereits 1994 stellte die Cherry mit der G80-5000 ein Modell mit gebrochenem Layout vor, geringe Abverkaufszahlen führten jedoch dazu, dass das Modell bereits drei Jahre später wieder vom Markt genommen wurde. Grund für die geringe Akzeptanz dieser Tastaturen ist laut einigen Umfragen und nach Ansicht vieler Branchenexperten die lange Eingewöhnungszeit die das ungewohnte Layout mit sich bringt. Selbst 10-Finger-Schreiber benötigen bis zu zwei Monaten ehe sie die Tastatur problemlos bedienen können. Die Cherry hat sich aufgrund dieser Erfahrungen dazu entschlossen das allgemein akzeptierte Standard-Layout hinsichtlich ergonomischer Anforderungen zu verbessern und die Arbeit damit für die breite Masse angenehmer zu gestalten, anstatt ein ergonomisch optimiertes Produkt auf den Markt zu bringen, das von < 1% (Quelle: GfK) der Verbraucher genutzt wird.

Die Basis der Tastaturen aus der eVolution-Serie bildet daher immer das so genannte Standard Layout bezüglich Tastenanordnung, Tastenanzahl und Tastengröße. Ergonomische Vorteile in Bezug auf die Handhaltung bietet besonders die ultraflache Bauweise (bei eingeklappten Aufstellfüßen 0 Grad Neigungswinkel). Die Neigung des Tastaturfeldes sollte möglichst gering sein, da die Blutbahnen, Sehnen und Nerven im Handgelenk bei zu stark angewinkelten Händen verengt werden. Schmerzen sind die Folge. Die konkave Tastenform verhindert ein Abrutschen der Finger. Die Hände können locker, ohne Verspannungen auf die Tastatur aufgelegt werden.

1. Zustätzliche Belastungen für Körper, die Augen, das Sehvermögen und die Psyche sind ausgeschlossen. Die Tastatur lässt sich ermüdungsfrei benutzen

Aufgrund des geringen Tastenwegs (MARLIN Wireless Laser MultiMedia Desktop, STINGRAY Wireless MultiMedia Desktop und BARRACUDA Wireless MultiMedia Desktop: ca. 2 mm Hub. STREAM Corded MultiMedia Keyboard: ca. 4 mm Hub) wird weniger Kraft zur Betätigung der Tasten benötigt. Das schont die Gelenke und beugt Ermüdungserscheinungen vor. Trotz des geringen Tastenwegs ist der Druckpunkt deutlich wahrnehmbar. Die taktile Rückmeldung - d.h. der Druckpunkt gibt dem Benutzer eine Rückmeldung des Anschlags. Die Meldung „Anschlag gelungen, mit dem Tippen kann fortgesetzt werden“ geht ans Gehirn weiter - laut ISO-Norm - ist gewährleistet.

Zur Schonung der Augen muss laut GS Siegel der Kontrast der Tastenbeschriftung im Verhältnis 3:1 stehen. Die geprüften Tastaturen von Cherry erreichen sogar einen Kontrast von 10:1.

Besonders in Großraumbüros kann der laute Anschlag von einigen zeitgleich genutzten Tastaturen die Nerven belasten und das Konzentrationsvermögen mindern. Der Flüsteranschlag der Cherry Tastaturen (mit 0,8 Sone best in class => Test ComputerBild September 2006) reduziert die Lautstärke erheblich, gibt aber dennoch die notwendige akustische Rückmeldung an den Benutzer.

PDF Manual

Deskthority wiki contributor Dirge has uploaded a copy of the windows (latter) variant manual. However, the file was never linked to any webpages neither has much information been provided on the said file in terms of licenses for instance. Link to manual (English): File:G80-5000.pdf

Virtual keyboard layout

Here are the rough visual representations of the keyboard. This mainly applies to DE ISO users due to the layout which is imposed via both the physical design as well as the machine set up. More virtual keyboard layouts are welcomed. These were made with the use of keyboard layout editor tool:

Keyboard layout editor - http://www.keyboard-layout-editor.com

• 

  "T1" layout. Labelled as is on G80-5000 HAMDE with the exception of windows and context menu keys. Extra characters can be accessed via holding "Alt Gr" key and pressing the corresponding key.

• 

  "T2" layout. Again with the exception of windows and context menu keys. Further extra characters can be accessed via holding both the "Shift" and "Alt Gr" key as well as pressing the corresponding key.
