Apple II is a family of microcomputers from Apple. For the most part, the keyboards used discrete metal contact switches, and in most cases the keyboard was integrated into the computer housing.

Models

The following lists are not exhaustive.

Apple II

Apple II Plus/II Europlus

  • Datanetics DC-50 series[1]
  • Rumours suggest a possible pre-RFI keyboard that may not have been Datanetics, but this has yet to be confirmed or denied with any details; Mike Willegal does note that "[with] the next version keyboard, the MM57040/AAE encoder was replaced by a separate plug in encoder that contained a SMC KR3600 encoder"[1] — this version came between the single-board Datanetics keyboards and the two-board RFI-compliant version
  • The Keyboard Company keyboard with ITT snap-action array (the first RFI-compliant keyboard)[1][2]

Blue PCB snap-action array

This keyboard is damaged. Most noticeably, one of the mounting bars has been snapped off. There is also a missing key position as well as dislodged leaf springs.

Cream PCB snap-action array

This keyboard is stamped "TKC", indicating that it was manufactured by The Keyboard Company. The Keyboard Company became the Apple Accessory Products Division (APD), and this model of keyboard has also been found with "APD" production labels on it.[3]

Apple IIe

Apple IIe Enhanced

Apple IIc

At least two keyboards have been found to date.[6] The original keyboards used Apple hairpin spring switches and were made by an unknown OEM; these were followed by a keyboard made by Alps Electric.

Unknown OEM

The first keyboard was sold from April 1984 to August 1986; the manufacturer of this keyboard is unknown. Some PCBs are labelled "Photocircuits Atlanta" but it is likely that Photocircuits Corporation was only one of at least two PCB manufacturers selected by the OEM. At least one of the PCBs lacking top branding has a logo on the trace side, which is partially obscured in photo below. A label reading "HASCO" appears on one such keyboard, but this cannot presently be traced to anyone in particular.

These keyboards use Apple hairpin spring switches for normal keys. The keyboard also has three latching switches: caps lock at the bottom left, and 80/40 and keyboard at the top left. Caps lock uses an Alps SKFL Lock switch; the other two latching keys can be either SKFL Lock or USw LZQW01.

These keyboards use a plastic girder under the PCB instead of a metal mounting plate above the PCB.

Type 1.A

Photocircuits Atlanta PCB, with Alps SKFL switches.[7] The PCB is marked "©1983".

Type 1.B

Photocircuits Atlanta PCB, with USw LZQW01 latching switches.

Type 1.C

PCB of unknown manufacturer, with SKFL Lock switches.

Type 1.D

PCB of unknown manufacturer, marked "©1983"; this has USw LZQW01 switches.

Type 2

This was sold from September 1986 to August 1988 when Apple switched to Alps as a manufacturer. Normal keys use Alps SKCM Amber and latching keys use Alps SKCL Lock. The keyboard identifying code is 12KC538A.

Apple IIc Plus

Apple IIGS

The Apple IIGS shipped with the external Apple Desktop Bus Keyboard and the Apple Desktop Bus Mouse. The Apple Desktop Bus protocol was introduced with this computer.
