The Dell '''AT101''', '''AT102''', '''AT101W''' and '''AT102W''' keyboards, amongst others, are part of a series of originally [[Alps Bigfoot]] keyboards manufactured in the 1990s for [[Dell]] for their range of desktop computers. This series primarily used tactile [[Alps SKCL/SKCM series]] switches, but [[rubber dome]] models also existed.

Versions with [[Windows key]]s have model names suffixed with 'W', e.g. Dell AT101'''W'''. ISO layout versions are called AT10'''2''' instead, with or without Windows keys. JIS layout version are called AT10'''3''', even though they have 106 keys. Variants with [[rubber dome]] switches have the suffix '''R''' in the model name.

==Nomenclature==
Alps versions appear to all be labelled "MODEL 101", from "Family Number: AT101-102", even in Japanese layout. There does not appear to be an actual "AT101" keyboard, and the name "AT101" appears to have been adopted in error.

The Silitek-made versions with rubber domes or Windows keys do however have model numbers beginning "AT": "AT101R", "AT103R", "AT101W" and "AT102W". Some Silitek-made versions are labelled only with their Dell part numbers, and offer no model number or FCC ID.

==History==
The Dell AT101 series was introduced as an [[Alps Bigfoot]] keyboard, with [[Alps SKCM Salmon]] switches and thick dye-sublimated keycaps with dark blue legends.

Around 1992, production transferred to Silitek. With this came thin keycaps and a move to [[Alps SKCM Black]] switches. The keycap printing method is not confirmed. Evidence indicates that salmon Alps was still made and sold at this point in time, so the change of switch is not understood. Alps Bigfoot keyboards were also still being made; it remains a mystery how and why production of an extant Alps design was moved to Silitek, and whether this was done with or without Alps's participation and agreement.

Silitek also introduced a [[rubber dome]] version of the keyboard.

The Windows key versions introduced laser-etched legends. These were produced until at least 2001.

==Construction==
The keys use [[switch mount|plate-mounted]] tactile [[Alps SKCL/SKCM series]] switches (either salmon or black). The [[keycap]]s are reported to be ABS; while yellowed examples are very rare, an Alps-made AT101 has been found with all keycaps except space bar the original colour, suggesting the use of PBT for all keycaps except space bar.<ref>Deskthority — [http://deskthority.net/keyboards-f2/some-alps-goodness-dell-at101-aekii-t7875.html Some Alps goodness (Dell AT101, AEKII)]</ref> Early keyboards had printed keycaps, while the 'W' variations have laser-etched keycaps.

The case is largely the same in all variations, with a cable channel on the bottom. Some collectors are of the opinion that cases made by [[Silitek]] are in a plastic of less quality than Alps's original case. Later examples use ABS keycaps, and often suffer from random distribution of keycaps that have faded more than others.

The connector can be either [[AT keyboard interface|PC/AT]] or [[PS/2 interface|PS/2]].

====Dell AT102====
102-key ISO layout version of the AT101.

;FCC ID GYUM95SK
:New logo.

====Silitek-made JIS====
106-key JIS layout version of the AT101, new logo.

A couple of variations have been encountered. These are made by Silitek; the Alps-made version is Model 101.<ref name="AT103">ちゃたりたいね — [http://kbd.rzw.jp/alps/dell_30383/ DELL KEYBOARD MODEL 30383 ALPS黒軸]</ref>

===Keyboards with Windows keys===
The keyboards have 1.25 [[unit]] [[Windows key]]s on the bottom row. 

The keyboard was available in beige and in black with white legends.

The keycaps are laser-etched and thin.
Unlike its predecessor the keys on the bottom row have the same profile as the space bar.

The circuit board inside is smaller than the AT101 variations, but the case is largely the same, except that there is no plastic between Ctrl and Alt keys.

The key switches are [[Alps SKCM Black]] in all variations.

Variations have been made in Taiwan, Mexico, Malaysia and Ireland.

====Dell AT101W====
[[ANSI]] layout version with 104 keys.

==Related keyboards==
Similar keyboards, with a similar case and [[Alps SKCL/SKCM series]] switches have also been made for e.g. Hewlett-Packard, Fujitsu, Mitsubishi, [[SGI Granite|Silicon Graphics]] and Sanyo, but not always with the same switch variation. Among Japanese keyboard collectors, these keyboards are referred to as [[Alps Bigfoot]].
