Apple extended wired. No. A1243.
Ah. The first and last good chiclet keyboard (along with it's contemporary wireless, non-numberpad and MacBook variants) ever made! Actually converted me from full-travel to chiclet - certainly better than most of the 'spongey' cheap 'full travel' keyboards.
I managed to blag a couple before they stopped making them but I'm on my last one. Might splash out for a proper 'mechanical' keychron or something when it expires.
I got a 2017 Tragic Keyboard + number pad with a new iMac some years ago, and it really is a travesty of the A1243. Shorter travel, plasticky-feeling keys, larger keys that make it feel more cramped, manages to weigh less than the A1243 even though it contains a battery (Hint to Apple - lighter is not better for something designed to sit on a desk and be pounded). Apart from being horrible to type on (I did give it a good chance before going back to the A1243) after about 6 months total use it was shaped like a banana where the keybed had bowed in the middle and the letters had already worn off some of the keys to the same extent as the A1243 that I'd been bashing for a decade... Total piece of tat, sorry.
Both the Magic Mouse and the Magic Keyboard are non-magical for me, I'm afraid. I do like the Magic Trackpad - but for a few things you really need a mouse for precision so I keep reverting back.
Main problem is being in the UK and Apple insisting on using their weird half-way-house between US and "standard" British layout (still has double-quotes on the 'wrong' key, no dedicated # key, other symbols in odd places) - which limits the choice of third party keyboards a bit because you can't just use a British PC keyboard. I did manage to find a British layout definition file at one stage, but that stopped working with an OS update.
