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 keys have model names suffixed with 'W', e.g. Dell AT101W. ISO layout versions are called AT102 instead, with or without Windows keys. JIS layout version are called AT103, 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 plate-mounted tactile Alps SKCL/SKCM series switches (either salmon or black). The keycaps 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.[1] 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 PC/AT or PS/2.

Keyboards with Windows keys

The keyboards have 1.25 unit Windows keys 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.

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, Silicon Graphics and Sanyo, but not always with the same switch variation. Among Japanese keyboard collectors, these keyboards are referred to as Alps Bigfoot.
