This keyboard is a variant of the Cherry G80-1800 family. Most keyboards found have been an integrated part in Dolch PAC computers, but a Cherry G80-1813HFU keyboard has also been found in a regular Cherry G80-1800 case.

The switches are PCB-mounted Cherry MX Blue, with a Cherry MX Green switch for the space bar.

The keycaps are made of double-shot moulded ABS in Dolch's colour-scheme of medium and dark grey, and have white legends. The key profile and font is the same as Cherry's other double-shot keycaps. Because of the popularity of these keycaps, the keyboards themselves now fetch a higher price on the second-hand market than the rest of the Dolch PAC units that most of them came with.

Cherry G80-1813

G80-1813HFU

White case, like a regular Cherry G80-1800 keyboard. The keyboards has (so far, out of a Dolch case) only been spotted as winkeyless US-ANSI (Cherry G80-1813HFU).[1]

Dolch

G80-1813HFX from a Dolch PAC-62 Network Analyser

Dolch Computer Systems made a series of "luggable" PCs with special-purpose hardware and software for sniffing wired communication networks for testing purposes. The keyboards cases were made to mate to the side of the computer, covering its LCD screen.

Dolch used Cherry as an OEM for the keyboards for several variations of the Dolch 486, and the PAC series: Dolch PAC 60, PAC 61, PAC 62, PAC 63, PAC 64 and for some Dolch PAC 65. The mechanical keyboards were labeled G80-1813HFX on the circuit board, and are in effect winkeyless G80-1813 keyboards with a different case and cable.

Related keyboards

Some PAC 65 contain a scissor-switch keyboard, presumably not made by Cherry.

There is also an older variant of Dolch computers where the keyboard has Cherry MX switches but where nothing else was made by Cherry. That keyboard's keys are thinner with pad-printed legends in the same colour scheme, except that some legends are red.

There are also Dolch keyboards in the same colour scheme, but with Cherry ML switches and a trackpad.

Variations

Some Dolch PAC 65 keyboards (Cherry MX or scissor-switch) also have a trackpoint above the numeric key pad. Trackpoints are cyan, like the cyan field in the Dolch logo.

Layouts that have been spotted so far are: US-ANSI, UK (ISO), German (ISO) and Italian (ISO). Although some computers are from the Windows 95 era, none has Windows keys.

Case

The Dolch keyboard's case is sturdier than Cherry's and is practically flat but has retractable feet if inclination is desired. The controller is located above the function keys instead of under the main PCB. Unlike other G80-18xxs, the keyboard's LEDs are on a separate circuit board connected with wires to the LEDs original position on the controller board.

Cable

All keyboards speak the PS/2 protocol. The PAC-60 has a detachable PS/2 cable. The PAC-61 and upwards have a instead a cable with a (telephone-style) modular connector; it is not directly detachable from the keyboard, but ends in a modular connector inside the keyboard's case.

Keyboards without trackpoints have a 4P4C connector. The pins are GND, +5V, kb data, kb clock (in order on the keyboard's side). Dolch PAC-65 keyboards with trackpoints have a larger modular connector and cable.

Key cap replicas

Several Dolch-lookalike key sets have been made by keyboard enthusiasts, including a Moogle kit for the use of Dolch keys with more common layouts. The colour of the alphanumeric keys matches Signature Plastics colour code 'GE', and the colour of the modifier keys matches colour code 'GX'.

The most notable are the keycaps group order from Signature Plastics by user:7bit, such as the "Round 3", and Round 3 - style key caps in Round 4. However, 7bit's rounds have centred legends and in Signature Plastics' font, not Cherry's. The profile of the bottom row keys is different, but otherwise practically the same.
