The Apple Extended Keyboard (AEK, model M0115) is a keyboard that was first sold separately alongside the Macintosh II and SE starting in 1987. It was replaced in 1990 by the Apple Extended Keyboard II (AEKII, model M3501) which was pre-packaged with Apple Professional Desktops starting with the Macintosh IIsi. Both versions were very similar, differing primarily with the. Get 6 months free of Apple Fitness+ when you buy Apple Watch, or get 2 months free, just for being a My Best Buy® member.

The Apple Extended Keyboard (AEK, model M0115) is a keyboard that was first sold separately alongside the Macintosh II and SE starting in 1987. It was replaced in 1990 by the Apple Extended Keyboard II (AEKII, model M3501) which was pre-packaged with Apple Professional Desktops starting with the Macintosh IIsi.
Both versions were very similar, differing primarily with the addition of adjustable height legs in the AEKII and other minor changes. Both used Apple Desktop Bus (ADB) to connect to the host computer, with ports on either side to allow daisy chaining of another input device, typically a computer mouse or trackball.
The move to USB connections starting with the original iMac led to the introduction of new keyboard designs using rubber dome switches rather than Alps Electric switches. This, in turn, has led to a market for 3rd party keyboards that replicate some of the AEK feel, with Matias' line of Tactile Pro and Quiet Pro keyboards perhaps being the most notable.

Unique features[edit]
Among the features that make this keyboard unique are:
- A separate power key using a different key cap.
- Caps Lock Key that physically locks down when activated, considered to be better for touch typists.
- Alps Electric Co. brand mechanical key switches, credited for their good sound and feel.
- Large spacing between keys, especially the top function keys and others.
- The width of the keyboard matches the width of the Macintosh II.
- The height allows it to fit under the 'chin' of the Macintosh SE.
- Two small cylinders project vertically from the top of the keyboard on either side of the function keys. These were used to hold templates with application-specific key guides.
Design[edit]
This side view of the Extended II shows its S-shaped upper surface, one of the two ADB ports, the deep serrated case which can rest on the desktop, and the single wide support leg that angles it upward.
The original Apple Extended Keyboard's case was sloped upward towards the rear so that when viewed from the side it formed a continuous convex curve. The case extended downward to sit on the desk, so it provided considerable internal volume. The case also had a significant amount of empty space at the rear, behind the top row of keys. This made for a relatively large and heavy case. The plastic of the case shell below the keyboard section on top was serrated, a common detail found on many Apple products of the era.
Unlike previous Macintosh keyboards, the key layout was very similar to the IBM PC AT's keyboard, in order to improve usability of MS-DOS programs (run via emulation or coprocessor board).
The II used an updated design that looked like a backward S when viewed from the side, starting relatively flat to the surface, sloping upward through the section where the keys were situated, and then flattening out again at the back where the function keys were placed. https://softneu.mystrikingly.com/blog/thirteen-deadly-sims-mac-os. The case did not extend down under the keyboard as much, instead, it was raised off the desk by an adjustable foot at the back. This design was lighter than the original at 3.75 pounds (1.70 kg) but otherwise similar in size.
The design patent for the Extended Keyboard II (D335,228) was filed on November 15, 1990.
In 1988 Apple Ireland commissioned Design ID, an industrial design consultancy based in Limerick, to assist with the development of the Extended Keyboard II. Original concepts were by Bryan Leech and Peter Sheehan. For the final proposal quieter key mechanisms were sourced, tested and specified, an adjustable foot was incorporated in the base and the keys were positioned to conform to European ergonomic standards. The ‘S curve profile’ matched the curving terraced key layout and was central to delivering the ergonomic improvements - aesthetics and function in a simple visual gesture.
The first working prototype of the Extended Keyboard II was produced at Design ID by Richard Howe, Donal Ryan and John Fitzgerald.
Steven Peart (frogdesign) was responsible for supplementary industrial design work and DFMA (Design for Manufacture and Assembly). Dexter Francis (Apple Peripheral Products Group) was the Apple in-house project lead/product designer.

Firmware Keys are keys which decrypt bootloaders, ramdisks, and root filesystem of iOS firmware, if those components are encrypted. Apple uses encryption to make it harder to analyze and modify them. Over time Apple changed the way they encrypt firmware files, hence the way to decrypt them and get decryption keys changed as well.
History
With the release of the iPhone came the IMG2 file format. They were used on all known iPhone OS1.x firmwares. For the 1.1.x series, they were encrypted with the 0x837 key. The discovery of the 0x837 key led to the ability to decrypt any 1.x firmware.
Following IMG2 came the IMG3 file format. They were introduced with iPhone OS 2.0 beta 4, and have been in use ever since. In order to maintain their integrity, they use multiple layers of encryption. Apple took encryption seriously with IMG3 by utilizing AES (based on the Rinjndael key schedule). In terms of the pre-iPhone OS 3 VFDecrypt key, it is stored as plain-text in the '__restore' segment of the ASR image within the ramdisks.
The ramdisk keys can only be retrieved with the processor specific GID Key. The GID key is currently unretrievable and can only be utilized through the built-in AES engine. To complicate things even more, the engine is only accessible through a special bootrom or iBoot exploit (jailbreaks typically expose it with /dev/aes_0). This makes usage of the key nearly impossible.
However, once you have access to the AES engine, the entire system falls apart. You are able to upload an encrypted ramdisk and grab the decryption keys for it. Once you manage to decrypt the ramdisk, you can run it through GenPass to decrypt the firmware key.
To find the keys, you can either use the methods on AES Keys or the easier option for OS X, keylimepie.

GID AES is used by iBoot to decrypt firmware images. When iBoot loads the kernelcache, GID AES is disabled. This means in order to get firmware keys, you must gain code execution in a setting where GID AES is still enabled. In most cases, this means exploiting iBoot itself, before the kernelcache is loaded.

This list also contains a few firmwares for which there never was an IPSW (as far as can be told) such as 4.2.5 for the CDMA iPhone 4 (iPhone3,3). These few builds came preinstalled on the device, but are not available for download.
